Better Workouts Include the Brain and Body

Posted on by

Movement is Medicine: ‘We can use our bodies as a tool to affect the way we think and feel, like a hotline to the mind.” Caroline Williams, researcher and author of ‘Move: How the New Science of Body Movement Can Set Your Mind Free’

“Movement affects your brain; but your brain also affects movement.”

Regular physical activity is an important part of a healthy mind, body and lifestyle. Not only is exercise good for your muscles and bones, but it is also an important part of keeping your brain healthy too. Exercise doesn’t only mean working out or playing sports, it just means moving your body and being active. A few other examples of exercise are: dancing, walking, biking, swimming, or throwing a Frisbee.

What happens in the body and brain during exercise: As your heart rate increases during exercise, blood flow to the brain increases. As blood flow increases, your brain is exposed to more oxygen and nutrients. Exercise also induces the release of beneficial proteins in the brain. These nourishing proteins keep brain cells (also known as neurons) healthy, and promote the growth of new neurons. Neurons are the working building blocks of the brain. As a result, individual neuron health is important to overall brain health.

Studies have shown that the connection between your brain and your body is a “two-way street” and that means physical movement can effectively change your brain for the better, explains Srini Pillay, M.D., Assistant Professor of Psychiatry at Harvard Medical School.

Your brain plays a major role in your physical and emotional well-being, and it directly affects your ability to exercise. Your brain was designed for survival and avoiding danger (fight, flight or freeze). Regular aerobic exercise can reduce anxiety by making your brain’s “fight, flight or freeze” system less reactive.

One way to trick your brain is doing a Gatorade swish, which misleads your brain into thinking your body is getting a jolt of energy from a sugary beverage, even if it isn’t. The act triggers the brain, which naturally wants to preserve energy for survival, into releasing dopamine to help jump start exercise based on the false promise is sugar, Dr. Jennifer Heisz, explains in Move Your Body; Heal Your Mind.

Movement can improve your cognitive functions and mental health. Regular physical activity and movement benefit more than just the body. They actually augment brain function. Movement supplies brain cells with oxygen, promotes the production of new brain cells, and aids in creating new synapses.

Regular exercise such as aerobic, resistance, flexibility, and balance exercises can reduce depressive symptoms. Exercise can be as effective as medication and psychotherapies.

Regular exercise may boost mood by increasing a brain protein called BDNF that helps nerve fibers grow.

Mindfulness during exercises and workout.

“A 12 minute walk alters metabolites in our blood, molecules that affect the beating of our heart, the breath in our lungs, the neurons in our brain.” explains Annabel Streets, “52,ways to Walk: The Surprising Science of Walking for Wellness and Joy, One Week at a Time.

Physical activity is ignored by experts who are too focused on addressing mental health issues from the neck up. “It’s low hanging fruit,” she says, “brain chemist, thought, behaviors might take years to address on the couch.” Dr. Ellen Vora, a New York psychiatrist.

“The brain is always working against you to not expend energy, but we can override it,” says Dr. Heisz.

Exercise can be turned into a powerful meditation practice states Anita Sweeney, author of “Make Every Move a Meditation: Mindful Movement for Mental Health, Well-Being, and Insight”. Exercise can be turned into a powerful meditative practice by focusing the mind on a single thought, object or sensation during exercise can help bring clarity and peace of mind. For example, focusing on your left foot hitting the pavement can help you focus.

Exercise is essential for those seeking better emotional well-being and better mental health. Both physical exercise and meditative movement are activities that you can do to improve the way you feel.

Studies have found that people who exercise daily are at greatly reduced risk of developing Alzheimer’s disease and dementia. Rudolph Tanzi, Kennedy professor of neurology and cofounder of the McCance Center for Brain Health at MGH, states, “It’s hard to imagine anything better for brain health than daily exercise, and our findings shed new light on the mechanism involved: protecting against neuroinflammation, perhaps the biggest killer of brain neurons as we age.”

Sugar – Detrimental to Your Immune System Health

Posted on by

The ‘worst food ingredient for your immune system’— sugar. Most Americans consume between 19 and 25 teaspoons of added sugars daily.

Metabolic disorders, like obesity and diabetes, have surged in the U.S. over the past several decades. Experts believe that sugar consumption is the major cause of obesity and chronic diseases, such as type 2 diabetes.

According to many immunologist, having diabetes means your body is in a chronic low-grade inflammatory state, which stresses the body’s innate immune system and makes it slower to jump on pathogens, like COVID19, when they enter the body. Chronic inflammation is an unhealthy and abnormal immune reaction in the body and added sugars are a key diet component known to exacerbate this type of inflammation.

When it comes to your immune system, it important that you understand that what you eat does matter a lot. And no ingredient is more detrimental to your immune system and physical health than added sugar.

From marinara sauce to peanut butter, added sugar can be found in even the most unexpected products. According to the Food and Drug Administration (FDA), added sugars include sugars that are added during the processing of foods (such as sucrose or dextrose), foods packaged as sweeteners (such as table sugar), sugars from syrups and honey, and sugars from concentrated fruit or vegetable juices. They do not include naturally occurring sugars that are found in milk, fruits, and vegetables. The Daily Value for added sugars is 50 grams per day based on a 2,000 calorie daily diet. For most Americans, the main sources of added sugars are sugar-sweetened beverages, baked goods, desserts, and sweets.

The American Heart Association (AHA) states individuals should limit their sugar intake to six to nine teaspoons each day, which is roughly the same amount of sugar in a single can of sugary soda: eight teaspoons.

Sugar is not just bad for your teeth. Too much sugar can contribute to chronic diseases, can affect the pH levels within the body, and can impact heart health and brain health. Basically, sugar can affect the health of both your mind and body.

In the US, added sugars account for up to 17% of the total calorie intake of adults and up to 14% for children, according to AHA. The 2020-2025 Dietary Guidelines for Americans recommend that you limit your added sugars consumption to 10% of total calories, making the current average consumption by Americans significantly higher than recommended.

Eliminating excess added sugar from your diet can not only help end this cycle of increasing metabolic disorders, but it can reverse it completely. Dialing back your sugar consumption is one of the most effective ways to improve your immune system and your overall health.

Preventative care, especially when it comes to an insidious disease like diabetes, it is recommended that the first step you take in your nutrition journey is to ask your health care provider to perform a fasting hemogoblin A1c test, even if your fasting blood glucose is normal.

Hemogoblin A1c tests measure average blood sugar over the previous three months, so even if your blood sugar is normal the day you see your doctor, the test can catch underlying issues.

According to Dr. Heather Moday, a board-certified allergist, immunologist and functional medicine physician, once you have an idea of where you stand on the blood sugar spectrum, you can take the steps below for better health:

  1. Cut back on added sugars. – This means eliminating candy, soda, cake and those seasonal flavored lattes from your diet. These foods and drinks don’t provide any nutritional value, and they contain massive amounts of sugar.
  2. Read the labels. – It is essential to check the amount of added sugar in every item in your pantry. The average American takes in about 17 teaspoons (71 grams) of added sugar a day, but the American Heart Association recommends no more than six teaspoons (25 grams) of added sugar a day for women, and nine teaspoons (36 grams) for men.
  3. Eat more fiber. – If sugar is bad, then fiber is the good. Fiber not only keeps your digestion regular, it also helps slow the absorption of sugar into your bloodstream, which protects you from sugar spikes. Lack of fiber is another reason why sodas, fruit juices and sugared coffee drinks are so detrimental to your health. They contain a ton of sugar and none of the blood-sugar-protecting fiber that fresh whole plant-based foods have. The best high-fiber foods are black beans and lentils, steel-cut oats, avocados, buckwheat, pears, raspberries, barley and flaxseeds.
  4. Chose nutrients over calories. – Instead of worrying about cutting calories, focus on adding more nutrient-dense foods to your diet, with lots of proteins and healthy fats. You don’t need to go low-carb, just choose the “right” carbs. In fact, eating carbs in the form of vegetables, beans, whole fruits, and nuts and seeds — all mineral- and vitamin-rich foods — is a great way to keep those hunger pangs at bay.

Sugar does occur naturally in all foods that contain carbohydrates, such as fruits and vegetables, grains, and dairy. Consuming whole foods that contain natural sugar is okay, according to Harvard Medical School. Plant foods also have high amounts of fiber, essential minerals, and antioxidants, and dairy foods contain protein and calcium. Since your body digests these foods slowly, the sugar in them offers a steady supply of energy to your cells.

However, problems do occur when you consume too much added sugar — the sugar that food manufacturers add to products to increase flavor or extend shelf life. “Excess sugar’s impact on obesity and diabetes is well documented, but one area that may surprise many men is how their taste for sugar can have a serious impact on their heart health,” says Dr. Frank Hu, professor of nutrition at the Harvard T.H. Chan School of Public Health.

Bottomline is that too much added sugar can be one of the greatest threats to cardiovascular disease and metabolic health. And, your consumption of added sugar must be drastically reduced or eliminated from your diet to improve both your cardiovascular and metabolic health.

The goal isn’t to completely eliminate dessert or sweets from your life, but to bring your added sugar intake into a healthier range.

Staying Active Gives You a Longer, Healthier Life

Posted on by

“Exercise is the most important activity we can do to keep our brains healthy, it’s important to simply move, whether that be casual walking or a workout.” Sanjay Gumpta

It important to understand that you can proactively take steps to avoid, delay, and mitigate dementia and mental decline as you age. Just thirty minutes daily of moderate physical activity, such as walking around the block, can make a significant difference in improving your brain health.

In the process of neurogenesis, creating brain cells does not stop when you age and get older. Neuroscientific research shows that the brain can make new brain cells, and forge new neural connections, at any age.

Additionally, adequate sleep also has a major effect on brain health. Recent research has shown that your brain remains very active while you sleep, because it can make full use of the energy that is diverted elsewhere when you are awake.

When you sleep, the brain turns information into knowledge, consolidates your memories, and cleans itself. This is why everyone needs at least eight hours of sleep, states Gumpta and you shouldn’t convince yourself that you don’t.

“There is a rinse cycle that happens in your brain when you sleep,” says Gumpta. “You are basically clearing out metabolic waste. That happens when you are awake, but the process is close to 60 per cent more efficient when you are asleep.

Key takeaway is that staying physically active, proper diet. adequate sleep and social interaction are all key to longer life.

And you’re never too old to start exercising.

Avoid 5 Foods that Weaken Memory and Focus

Posted on by

We are what we eat!

Across America, people are struggling with mental health issues. Nearly one in five Americans are living with a mental health condition, and the number of people seeking help for anxiety and depression is skyrocketing, reports Mental Health America. According to the organization’s 2021 State of Mental Health in America Report, “suicidal thoughts are increasing among both adults and children, and 9.7 percent of youth is experiencing severe major depression compared to 9.2 percent last year”.

Accumulating scientific research shows that a standard American diet rich in refined sugar and highly processed foods may increase the risk of developing or worsening various mental health conditions. But a nutrient-based diet rich in fresh fruits and vegetables; omega-3 fatty acids; nuts, seeds and legumes; whole grains, fresh herbs and spices; fish and olive oil, may help to support and enhance mental health.

Source: https://mhanational.org/issues/state-mental-health-america

A Harvard nutritionist and brain expert implores Americans to avoid 5 foods that ‘weaken memory and focus’, and increase the likelihood of depression and mental health issues. Dr. Uma Naidoo, a nutritional psychiatrist, brain expert, and faculty member at Harvard Medical School, studied how gut bacteria can trigger metabolic processes and brain inflammation that impact memory.

In her book “This Is Your Brain on Food”, Dr. Naidoo explains which food contributes to our mental health and “how a sound diet can help treat and prevent a wide range of psychological and cognitive health issues, from ADHD to anxiety, depression, OCD, and others”.

Refined sugar is well known for creating chronic inflammation in the body which can cause dysfunction of the immune system.

Existing studies indicate that you “may be able to reduce the possibility of dementia by avoiding foods that can compromise our gut bacteria and weaken your memory and focus”.

The standard American diet (SAD) foods “to avoid or cut back on to fight inflammation and promote brain health, sharp thinking and good decision-making” are:

  1. Refined sugars – a high-sugar or ‘high fructose corn syrup’ diet can lead to excess glucose in the brain, which studies have linked to memory impairments and less plasticity of the hippocampus — the part of the brain controlling memory. Consuming unhealthy processed foods like baked goods and soda floods the brain with too much glucose. And, be aware that refined sugar is “secretly added” to many popular food items like fast food french fries. Furthermore, sugar consumption triggers a cascade of chemical reactions in the body that promote chronic inflammation, according to Psychology Today. A little inflammation can be a good thing, since it can increase immune activity and blood flow to a wound. But in the long term, inflammation is a big problem. It disrupts the normal functioning of the immune system, and wreaks havoc on the brain.
  2. High-glycemic-load carbohydrates – your body processes high-glycemic-load carbohydrates in much the same way it does with refined or high fructose sugar. That means they can also raise your risk for depression. “Better-quality” carbohydrates were defined as whole grains, foods high in fiber, and those ranked low on the glycemic index (GI). The GI is a measure of how quickly foods convert to glucose when broken down during digestion; the faster a food turns into glucose in the body, the higher its GI ranking. Researchers discovered that people who were eating better-quality carbs, were 30% less likely to develop depression than those who were eating high-GI carbs. Low-GI carbs include green vegetables, most fruits, raw carrots, kidney beans, chickpeas and lentils.
  3. Fried foods – for brain health, it pays to reduce the amount of fried foods you eat. In fact, one study found that a diet high in fried foods was linked to lower scores in learning and memory. The likely reason is that fried foods can cause inflammation, which can damage the blood vessels that supply the brain with blood. Another study found that those who consumed more fried foods were more likely to develop depression in their lifetime. If you’re eating fried foods, try enjoying them just once a month.
  4. Alcohol – Archana Singh-Manoux, a research professor and director at the French Institute of Health and Medical Research, and her colleagues reported in the British Medical Journal that “people who had abstained from alcohol completely or who consumed more than 14 drinks per week had a higher risk of dementia compared to those who drank alcohol in moderation”. Thus, the key is moderation.
  5. Nitrates – nitrates are used as a preservative and to enhance color in deli slices and cured meats like bacon, salami and sausage. Nitrates may be also connected with depression.

What you eat does matter. Thus, by avoiding or eliminating these 5 foods from your diet, and by serving healthier, nutrient-rich food options, you can help to alleviate anxiety and depression, stabilize mood and promote mental health and wellness.

“The gut/brain connection helps us understand the food/mood connection,” explains Dr. Naidoo. “The enteric nervous system—that is, the nerves supplying the gastrointestinal tract—totals over 100 million neurons and communicates directly with the brain, or central nervous system, by way of the vagus nerve, which is responsible for our ‘rest-and-digest’ response. 

“It’s also vital to note that the gut contains the highest number of serotonin receptors, and the gut itself produces all the neurotransmitters that are also made in the brain, including serotonin, often called the happiness hormone. In turn, these neurotransmitters are implicated in sound mental health or potential problems when they are deficient.”

Bottomline, cleaning up your diet and eating healthier, nutrient-rich food, in most cases, will only help your mental health and emotional well-being.

Healthy diet, exercise, mindfulness, gratitude and sleep are all holistically important for your brain and mental health.

The brain-changing benefits of exercise

Posted on by

Wendy Suzuki • TEDWomen 2017 • October 2017

“Just a walk around the block or a 10-minute online workout will not only improve your day but also benefit your brain in a lasting way.” Wendy Suzuki

What’s the most transformative thing that you can do for your brain today? Exercise! says neuroscientist Wendy Suzuki. There is extensive scientific research behind the extraordinary, life-changing effects that physical activity can have on the most important organ in your body: your brain.

Get inspired to go to the gym or to go for a jog

Suzuki discusses the science of how working out boosts your mood and memory. “Every time you work out, you are giving your brain a neurochemical bubble bath, and these regular bubble baths can also help protect your brain in the long term from conditions like Alzheimer’s and dementia”, she explains.

A single workout increases neurotransmitters like dopamine, serotonin and noradrenaline, and these mood boosters can also improve your memory and focus for up to three hours afterwards.

Dr. Wendy A. Suzuki is a Professor of Neural Science and Psychology in the Center for Neural Science at New York University, an author, storyteller and fitness instructor. Her work has focused on understanding how aerobic exercise can be used to improve learning, memory and higher cognitive abilities in humans.

Other Long-term Benefits

Regular exercise and physical activity provides many other important health benefits for chronic disease prevention, according to the Centers for Disease Control and Prevention.

  • Heart Health – Lowers risk of heart disease, stroke, and type 2 diabetes
  • Cancer Prevention – Lowers risk of eight cancers: bladder, breast, colon, endometrium, esophagus, kidney, lung, and stomach
  • Healthy Weight – Reduces risk of weight gain
  • Bone Strength – Improves bone health
  • Balance and Coordination – Reduces risks of falls

Exercise and Physical Activity Guidelines

Medical doctors and other health professionals recommend exercise and physical activity, based on the 2018 Physical Activity Guidelines. Adults of all shapes, sizes, and abilities can benefit from being physically active.

  • All adults should avoid inactivity. Some exercise and physical activity is better than none, and adults who participate in any amount of physical activity gain some health benefits.
  • Aerobic activity of any duration may be included in the daily accumulated total volume of physical activity.

For important health benefits, all adults should do both aerobic and muscle-strengthening physical activities.

– For Aerobic:

  • At least 2 hours and 30 minutes (150 minutes) a week of moderate-intensity aerobic physical activity (i.e., brisk walking; wheeling oneself in a wheelchair); or
  • 1 hour and 15 minutes (75 minutes) a week of vigorous-intensity aerobic physical activity (i.e., jogging, wheelchair basketball); or
  • A mix of both moderate- and vigorous-intensity aerobic physical activities each week. A rule of thumb is that 1 minute of vigorous-intensity activity is about the same as 2 minutes of moderate-intensity activity.

– For Muscle-Strengthening:

  • Activities that are moderate or high intensity and involve all major muscle groups on 2 or more days a week (i.e., working with resistance bands; adapted yoga) as these activities provide additional health benefits. (Source: CDC)

Regular exercise and physical activity is one of the most important things you can do for your brain and overall health!

Intermittent Fasting to Hearth Health

Posted on by

“Intermittent Fasting may bring heart health and other health benefits.”

Intermittent fasting can offer many health benefits. It can aid in weight loss, control diabetes and prevent many other health conditions, according to several medical experts.

The benefits are thought to result from a process called metabolic switching, which is when the body goes into a fasting state and begins using body fat instead of glucose to meet its energy needs, according to Consumers Reports.

Intermittent fasting helps preserve the body’s normal interplay between the hormone insulin and blood glucose, preventing insulin resistance (when the body doesn’t respond properly to it). Metabolic switching also signals the body to activate maintenance and repair systems, which aid in disease prevention.

Intermittent fasting is an eating plan that focuses more on when to eat than what to eat.  And, more people are trying intermittent fasting due to its abundance of impressive health results from scientific studies, word of month and social media. Intermittent fasting has become the number one fasting technique and a popular weight loss tactic.

Fasting is voluntary and controlled period without food. Fasting, especially intermittent fasting, is for health, religious and spiritual reasons.

Eating cycles involve fasting for a period of time and eating for the rest. These periods can be aligned to a person’s lifestyle, dietary requirements or health conditions.

When You Eat Matter

It seems that regularly fasting can potentially improve your risk factors related to heart health. Although researchers aren’t sure why, at least one study has indicated that people who follow a fasting diet may have better heart health than people who don’t.

Regular fasting and better heart health may be linked to the way your body metabolizes cholesterol and sugar. Regular fasting can decrease your low-density lipoprotein (LDL), or “bad,” cholesterol. It’s also thought that fasting may improve the way your body metabolizes sugar. This can reduce your risk of gaining weight and developing diabetes, which are both risk factors for heart disease.

More studies are needed to determine whether regular fasting can reduce your risk of heart disease. Most scientific evidence on fasting comes from animal, not human, studies. If you’re considering regular fasting, talk to your doctor about the pros and cons. Keep in mind that a heart-healthy diet and exercising regularly also can improve your heart health.

What you eat matters.

Many studies have shown that the types of food you eat affect your health. Additionally, scientists are beginning to understand that when you eat may also make a difference.

Throughout history, people have experienced periods when food was either scarce or completely lacking, says Dr. Valter Longo, an NIH-funded longevity researcher at the University of Southern California. “So, they were forced to fast,” he says.

But current technology “has shifted our eating patterns,” explains Dr. Vicki Catenacci, a nutrition researcher at the University of Colorado. “People now eat, on average, throughout a 14-hour period each day.”

Studies suggest that this constant food intake may lead to health problems and researchers have started looking at whether fasting can have potential health benefits for some people.

Intermittent Fasting

Many fasting diets mainly focus on the timing of when you can eat. These fasting diets are sometimes called “intermittent fasting.”

In intermittent fasting, you eat every day but only during a limited number of hours per day. Instead of eating three meals spread out during the day, you may only eat between a six- to eight-hour window each day and fast for the remaining sixteen to eighteen hour. For example, you might eat breakfast and lunch, but skip dinner.

The most popular intermittent fasting method is 16:8. This is a schedule that involves 16 hours of fasting and 8 hours of eating.

Other timed intermittent fasting similar to this include 12:12 and 14:10. The first number always indicates the hours you fast for. During fasting a person must not consume any food or calories. Calorie free drinks are allowed such as water, black coffee and tea.

Other methods include alternate day fasting. This is where a person fasts for 24 hours every other day or two days. For the other days a healthy nutritious diet should be consumed.

Another intermittent fasting method is 5:2. This involves eating healthy nutritious non-calorie restricting 5 days a week. The other 2 days a person should consume 600 calories or less.

But scientists don’t know much about what happens to your body when you fast. Most research has been done in cells and animals in the lab. That work has provided early clues as to how periods without food might affect the body.

Researchers have found that in some animals, certain fasting diets seem to protect against diabetes, heart disease, and cognitive decline. Fasting has even appeared to slowed the aging process and protected against cancer in some experiments.

“In mice, we’ve seen that one of the effects of fasting is to kill damaged cells, and then turn on stem cells,” explains Longo. Damaged cells can speed up aging and lead to cancer if they’re not destroyed. When stem cells are turned on, new healthy cells can replace the damaged cells.

Studies are starting to look at what happens in people. Early results have found that some types of fasting may have positive effects on aspects of health like blood sugar control, blood pressure, and inflammation. But fasting can also cause weight loss. So researchers are studying whether the beneficial changes seen in the body are side effects of the weight loss or the fasting process itself.

Body Changes

For many people, the main reason to try fasting is to lose weight. Currently, most people try to lose weight by restricting how many calories they eat each day.

“That doesn’t work for everyone,” Catenacci explains. “It takes a lot of focus. It takes a lot of math, and a lot of willpower.” Her research team is running a study to compare how much weight participants lose with fasting versus calorie restriction, but over a one-year period. “There’s a lot of debate about whether the benefits of intermittent fasting are due to the extended fasting period itself,” says Dr. Courtney Peterson, an NIH-funded nutrition researcher at the University of Alabama.

To understand this better, Peterson did a study in pre-diabetic men. It was designed so the volunteers would not lose weight. The men ate an early time-restricted feeding diet for five weeks. They could eat only between 8 am to 2 pm. They then fasted for the next 18 hours. Next, they ate the same amount of food but only during a 12-hour period per day for five weeks. None of the men lost weight.

The longer fasting period alone made a difference. The intermittent fasting diet “improved their blood sugar control,” Peterson says. “And we found a blood pressure lowering effect equivalent to what you see with a blood pressure medication.”

These findings suggest that an extended fast or the timing of when you eat—even when it doesn’t affect your weight—can bring health benefits for some people.

Health benefits of fasting

Fasting may bring health benefits, but Longo and other experts caution against people trying fasting diets that are not based on research. If you’re fasting, talk with your health care provider first. People with certain health conditions or who are taking certain medications should not try fasting.

Even if you fast sometimes, you still need to make healthy food choices overall, Peterson explains. “It looks like when you eat matters a lot, but what you eat probably matters more.”

Autophagy and Anti-Aging

After 16 to 18 hours of fasting, you should be in full ketosis. Your liver begins converting your fat stores into ketone bodies — bundles of fuel that power your muscles, heart, and brain.

If you can do intermittent fasting for 16-18 hours a day, you’ll burn through body fat and fill up quickly when you break your fast, which makes it easy to stay in a calorie deficit and lose weight.

When the body fasts and goes without food for an extended period of time, it begins a waste removal process. This is better known as autophagy.

Autophagy is a cellular process where the body removes old cells and replaces them with new healthier cells. Replacing old cells with new ones help the body fight disease and cancers.

Studies show that the autophagy process begins with long term fasting. Autophagy can only begin when glucose and insulin levels are low. It is a healthy process for cells and tissue to repair.

Studies suggests that autophagy begins after 24 hours of calorie restrictions. It can increase with exercise during periods of fasting.

After a full-day fast, your body goes into repair mode. It begins recycling old or damaged cells and reducing inflammation. If you’re looking for anti-aging or anti-inflammatory benefits, a 24-hour or greater timeframe fast is required. .

When your body is under mild stress (such as exercise or an extended fast), your cells respond by becoming more efficient.

Intermittent fasting is a valuable and an effective tool to improve your mental and physical health.

Celebrating American Heart Month

#1 cause of death in the U.S. is HEART DISEASE!

Heart disease is a catch-all phrase for a variety of conditions that affect the heart’s structure and function. Coronary heart disease is a type of heart disease that develops when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart.

Despite the devastating toll of COVID-19, heart disease remains the most costly and leading cause of death in the United States. Specifically, myocardial infarction (MI) and coronary artery disease (CAD) are the leading causes of death in the U.S. and other Western societies.

Coronary heart disease is often caused by the buildup of plaque, a waxy substance, inside the lining of larger coronary arteries. This buildup can partially or totally block blood flow in the large arteries of the heart.

Some types of this condition may be caused by disease or injury affecting how the arteries work in the heart. Coronary microvascular disease is another type of coronary heart disease. It occurs when the heart’s tiny blood vessels do not work normally.

The death rate from heart attacks has risen dramatically during the COVID-19 pandemic because people are delaying or not seeking care after experiencing mild symptoms. And, symptoms of coronary heart disease differ from person to person even if they have the same type of coronary heart disease. However, because many Americans have no symptoms, they do not know they have coronary heart disease until they have chest pain, a heart attack, or sudden cardiac arrest.

Protect yourself…

90% of heart disease and stroke is preventable through lifestyle changes and risk factor modification. During Heart Month, it is critical to recommit to fighting this disease by promoting better health, wellness, and prevention awareness in your homes and communities.

There’s a lot you can do to prevent heart disease. You and your friends and family can begin by working together to meet your heart health goals. Move more, work on your weight and salt intake, quit smoking—it’s all easier when you have social support.

Motivating Americans to adopt healthy lifestyles to prevent heart disease is the goal of Heart Month. Focusing on your heart health has never been more important. People with poor cardiovascular health are also at increased risk of severe illness from COVID-19.

Let’s celebrate American Heart month by incorporating heart-healthy cardio activity into your day today:

  • Get Moving (exercise)
  • Quit Smoking (No More Excuses)
  • Lose Weight (Your weight matters)
  • Eat Heart Healthy Foods (talk to a doctor or a nutritionist)
  • Don’t Overeat
  • Don’t Stress

Make heart health a regular part of your self-care routine.

Wish all a Happy Valentine’s Day, and to remind you to take care of your heart

The Gift of Exercise and Health

Posted on by

Make exercise a lifelong habit

Exercise and physical activity are great ways to feel better, boost your health and improve your life. The health benefits of regular exercise and physical activity are significant and hard to ignore. And, everyone would benefit from exercise, regardless of age, gender or physical ability.

Research demonstrates that lifestyle changes, like making exercise a lifelong habit, will have a strong influence on your heath. Thus, you must make healthy habits such as exercising or being physically active daily a lifelong goal and a lifestyle. 

Physical Activity is important

Exercise and physical activity are good for just about everyone. No matter your health and physical abilities, you can gain a lot by staying active. In fact, studies show that “taking it easy” is risky. Often, inactivity is more to blame than age when older people lose the ability to do things on their own.

Lack of exercise or physical activity also can lead to more visits to the doctor, more hospitalizations, and more use of medicines for a variety of illnesses. Research has shown also that it’s important to get all four types of exercise: endurance, strength, balance, and flexibility.

Physical activity predicts better health. 

People who rarely get off the couch are more than twice as likely to die prematurely as people who exercise moderately, whether they are normal weigh, overweight or obese.  In contrast, people who are obese and fit have only slight more risk than normal-weight, fit people, according to Dr. Sandra Aamodt, author of Why Diets Make Us Fat:  The Unintended Consequences of Our Obsession with Weight Loss (Penguin Random House, 2016).

The research indicates that exercise habits are much more important than weight in determining the risk of early death.  Bottom line is that “exercise improves health even if no weight is lost.” 

Low fitness is estimated to be responsible for 16 to 17 percent of deaths in the U.S.  While, obesity accounts for only 2 to 3 percent once the effects of fitness are factored out.

Exercising 30 minutes a day is more effective than dieting 24 hours a day.  That’s the deal of a lifetime–a longer, healthier lifetime. Thus, one of life’s best gifts is exercise.

Healthy habits for the heart. 

Regular exercise protects your heart and provides many heart-healthy benefits

Heart disease remains the leading cause of death in the U.S.  according to the Centers for Disease Control and Prevention. Your risk of many chronic diseases drops when you partake in regular exercise or physical activities. 

The American Heart Association recommends 150 minutes of moderate exercise every week; just 30 minutes of activity, such as walking, on five out of the seven days. 

Bottomline, exercise and physical activity across a lifetime can substantially reduce your risk of heart disease.

Seven benefits of exercise

There are seven ways exercise can lead to a happier, healthier you, according to the Mayo Clinic. The benefits of exercise are:

  1. Exercise controls weight
  2. Exercise combats health conditions and diseases
  3. Exercise improves mood
  4. Exercise boosts energy
  5. Exercise promotes better sleep
  6. Exercise puts the spark back into your sex life
  7. Exercise can be fun … and social!

As you can see, exercise is good for the body or mind. According to the Mayo Clinic, walking or moderate physical activity can improve heart health, lower blood pressure, strengthen bones and muscles, help maintain a healthy weight, and improve mood.

Fitness Program: Five Steps to a Healthy Lifestyle | Mayo Clinic

Posted on by

Any amount of physical activity or exercise is better than none at all.

By Mayo Clinic Staff

Starting a fitness program may be one of the best things you can do for your health. Physical activity can reduce your risk of chronic disease, improve your balance and coordination, help you lose weight, improve your metabolic health and reduce your metabolic age — and even improve your sleep habits and self-esteem.

There are three kinds of fitness:

• Aerobic fitness. Aerobic activities condition your heart and lungs. Aerobic means “with oxygen.” The purpose of aerobic conditioning is to increase the amount of oxygen that is delivered to your muscles, which allows them to work longer. Any activity that raises your heart rate and keeps it up for an extended period of time will improve your aerobic conditioning.

• Muscle strengthening. Stronger muscles can mean either more powerful muscles that can do bigger jobs (such as lifting heavier weights) or muscles that will work longer before becoming exhausted (endurance). Weight training (resistance training) or simple exercises such as push-ups are two examples of ways to focus on muscle strengthening.

• Flexibility. Like aerobic fitness and muscle strengthening, flexibility is a result of physical activity. Flexibility comes from stretching. Your muscles are repeatedly shortened when they are used, especially when exercising. They need to be slowly and regularly stretched to counteract the repeated shortening that happens through other activities.

You can start your personal fitness program with simple steps.

1. Assess your fitness level

You probably have some idea of how fit you are. But assessing and recording baseline fitness scores can give you benchmarks against which to measure your progress. To assess your aerobic and muscular fitness, flexibility, and body composition, consider recording:

  • Your pulse rate before and immediately after walking 1 mile (1.6 kilometers)
  • How long it takes to walk 1 mile, or how long it takes to run 1.5 miles (2.41 kilometers)
  • How many standard or modified pushups you can do at a time
  • How far you can reach forward while seated on the floor with your legs in front of you
  • Your waist circumference, just above your hipbones
  • Your body mass index

2. Design your fitness program

It’s easy to say that you’ll exercise every day. But you’ll need a plan. As you design your fitness program, keep these points in mind:

  • Consider your fitness goals. Are you starting a fitness program to help lose weight? Or do you have another motivation, such as preparing for a marathon? Having clear goals can help you gauge your progress and stay motivated.
  • Create a balanced routine. For most healthy adults, the Department of Health and Human Services recommends getting at least 150 to 300 minutes of moderate aerobic activity or 75 to 150 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. The guidelines suggest that you spread out this exercise during the course of a week. Greater amounts of exercise will provide even greater health benefits.

But even small amounts of physical activity are helpful. Being active for short periods of time throughout the day can add up to provide health benefits.
Do strength training exercises for all major muscle groups at least two times a week. Aim to do a single set of each exercise, using a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions.

  • Start low, develop exercise habit and progress slowly. If you’re just beginning to exercise, start cautiously and progress slowly. If you have an injury or a medical condition, consult your doctor or an exercise therapist for help designing a fitness program that gradually improves your range of motion, strength and endurance.
  • Build activity into your daily routine. Finding time to exercise can be a challenge. To make it easier, schedule time to exercise as you would any other appointment. Plan to watch your favorite show while walking on the treadmill, read while riding a stationary bike, or take a break to go on a walk at work.
  • Plan to include different activities. Different activities (cross-training) can keep exercise boredom at bay. Cross-training using low-impact forms of activity, such as biking or water exercise, also reduces your chances of injuring or overusing one specific muscle or joint. Plan to alternate among activities that emphasize different parts of your body, such as walking, swimming and strength training.
  • Try high-interval intensity training. In high-interval intensity training, you perform short bursts of high-intensity activity separated by recovery periods of low-intensity activity.
  • Allow time for recovery. Many people start exercising with frenzied zeal — working out too long or too intensely — and give up when their muscles and joints become sore or injured. Plan time between sessions for your body to rest and recover.
  • Put it on paper. A written plan may encourage you to stay on track.

3. Assemble your equipment

  • You’ll probably start with athletic shoes. Be sure to pick shoes designed for the activity you have in mind. For example, running shoes are lighter in weight than cross-training shoes, which are more supportive.
  • If you’re planning to invest in exercise equipment, choose something that’s practical, enjoyable and easy to use. You may want to try out certain types of equipment at a fitness center before investing in your own equipment.
  • You might consider using fitness apps for smart devices or other activity tracking devices, such as ones that can track your distance, track calories burned or monitor your heart rate.

4. Get started…get moving

Begin your fitness program and keep these tips in mind:

  • Start slowly and build up gradually. Give yourself plenty of time to warm up and cool down with easy walking or gentle stretching. Then speed up to a pace you can continue for five to 10 minutes without getting overly tired. As your stamina improves, gradually increase the amount of time you exercise. Work your way up to 30 to 60 minutes of exercise most days of the week.
  • Break things up if you have to. You don’t have to do all your exercise at one time, so you can weave in activity throughout your day. Shorter but more-frequent sessions have aerobic benefits, too. Exercising in short sessions a few times a day may fit into your schedule better than a single 30-minute session. Any amount of activity is better than none at all.
  • Be creative. Maybe your workout routine includes various activities, such as walking, bicycling or rowing. But don’t stop there. Take a weekend hike with your family or spend an evening ballroom dancing. Find activities you enjoy to add to your fitness routine.
  • Listen to your body. If you feel pain, shortness of breath, dizziness or nausea, take a break. You may be pushing yourself too hard. Remember to drink plenty of water.
  • Be flexible. If you’re not feeling good, give yourself permission to take a day or two off.

5. Monitor and track your progress

Retake your personal fitness assessment six weeks after you start your program and then again every few months. You may notice that you need to increase the amount of time you exercise in order to continue improving. Or you may be pleasantly surprised to find that you’re exercising just the right amount to meet your fitness goals.

If you lose motivation, set new goals or try a new activity. Exercising with a friend or taking a class at a fitness center may help, too.

Starting an exercise program equates to healthy habits that last a lifetime

Health, not gold or silver, is the greatest wealth! Billy Graham

Starting an exercise program is an important decision for your health and well-being. But it doesn’t have to be an overwhelming or strenuous or anxiety producing one. By planning carefully, starting slowing and pacing yourself, you can establish a healthy habit that lasts a lifetime

Healthy Diet for a Healthy Life | Consumers Reports

Posted on by

Eating a healthy diet can fix several common health concerns as you age like energy level, mood and balance.

A healthy diet is key to the healthy aging of your body and mind, according to Consumer Reports on Health. Additionally, it can help you ward off chronic diseases such as hearth disease, high blood pressure and type 2 diabetes.

Improving energy levels and mood

A healthy diet can help remedy numerous conditions (many of which become more common with age)—such as your balance and mood.

When the weather turns cold and days get shorter, we often turn to comfort foods which tend to be made mostly of refined carbohydrates, sugar, and fat. That combination may leave us feeling physically tired and emotionally cranky.

“When you eat simple, refined carbs, you get a quick increase of energy for about 20 or 30 minutes, and then a quick decrease,” says Lauri Wright, PhD, associate professor of nutrition at the University of North Florida in Jacksonville. “Those spikes and dips in energy are also bad for your mood because when your energy comes crashing down, your mood can crash too.”

Whole grains, such as brown rice and quinoa, work in the opposite way. “They release energy gradually and then gradually decrease over the course of 3 to 4 hours,” Wright says.

Getting adequate vitamin D may also be helpful for boosting your mood. Older adults may be prone to a defi­ciency, in part because the ability to produce D from sunlight declines with age. A 2018 study of almost 4,000 adults 50 and older in Ireland found that those with vitamin D deficiency (defined in this study as blood levels lower than 30 nanomoles per liter) were more likely to develop depression.

Improving balance

Your balance tends to get worse as you age, but one common cause is sarcopenia (age-related muscle loss). You can help your muscles stay strong by getting enough protein.

“The proteins in your muscles are constantly being broken down,” says Roger Fielding, PhD, associate director of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston. “If you aren’t consuming enough protein in your diet, the breakdown exceeds synthesis and you have a loss of muscle mass.” And without strong muscles to support your joints, your balance may suffer, leaving you at greater risk of falling.

On average, older adults should aim for at least 0.6 gram of protein per pound of body weight per day—about 90 grams for someone who weighs 150 pounds. Make sure to spread it evenly among meals. “It’s important to deliver protein to your muscles throughout the day,” Fielding says. And be sure to get a mix of animal (lean meats, fish, dairy) and plant (beans, nuts, soy) sources.

Plant foods also contain antioxidants and polyphenols that can help reduce inflammation. “Increases in inflammatory compounds can have potent effects on muscle loss,” Fielding says. In one study in The Journal of Nutrition, older men and women with adequate blood levels of antioxidant vitamin C had an average of 1.6 percent and 3.4 percent greater muscle mass, respectively, than those with lower levels.

Healthy eating

Eating lots of high-quality plant foods and eating low amounts of animal-based foods, refined grains, added sugars, processed foods and ­unhealthy fats is good for your heart health. A plant-based diet can improve cholesterol and lower blood pressure. It also helps to protect against oxidative damage and to reduce inflammation.

Research has linked ultra processed foods to a higher risk for obesity, heart disease, and cancer. Some processing is relatively benign and even enhances healthy properties. But generally speaking, the farther your food gets from its original “whole” version, the more process and less good it becomes for you.

Healthy eating plan

What matters most is following a healthy eating plan. In one 2018 study involv­ing more than 81,000 women, those whose diets most closely matched one of three heart-healthy eating patterns—alternate Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and 2010 Alter­native Healthy Eating Index—had a lower risk of developing chronic diseases over the 22-year study period.

To make it simple, at each meal fill half your plate with fruits and veggies (but limit starchy ones, such as potatoes). The other half should be made up of whole grains and plant-based protein, such as tofu, lentils, or nuts, most days, with modest amounts of fish, lean meat, and poultry less often.
