Your Gut Health May Improve

How Intermittent Fasting Affects Your Body and Brain | The Human Body

Many people who partake in intermittent fasting note improved gut health. Fasting gives your gut a chance to rest and reset as your digestive system doesnt have to deal with uncomfortable effects of eating like gas, diarrhea and bloating.

Anytime you fast, youre giving your body a break from trying to metabolize what you just ate, Zarabi said. By fasting, we let the gut microbiome refresh, which in turn improves our overall digestive pathway.

Fasting Can Help You Live Longer

Fasting for periods of 12 hours or longer can trigger what is known as autophagy;. Autophagy is a process that we go through on a regular basis as we age, and that is to regenerate and repair.

Its sort of like house cleaning on a cellular level.;

Old, dead proteins and other toxins that hang around too long tend to clog up our bodies and reduce daily function. This also speeds up the ageing process and can lead to a whole host of other age-related illnesses, including dementia.

There are a few methods that we can use to trigger this process of cell renewal. One of the most effective is fasting! Fasting lowers your insulin levels which can dramatically increase the autophagy process.

Intermittent Fasting May Cause Older Adults To Lose Too Much Weight

While intermittent fasting shows promise, there is even less evidence about the benefits or how fasting might affect older adults. Human studies have looked mostly at small groups of young or middle-aged adults, for only short periods of time.

But we do know intermittent fasting could be risky in some cases. “If you’re already marginal as far as body weight goes, I’d be concerned that you’d lose too much weight, which can affect your bones, overall immune system, and energy level,” says registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women’s Hospital.;

How Fasting Can Affect Your Body

Despite its newfound popularity, fasting has had a significant role in many cultures and religions throughout history. Fasting is defined as abstinence from all or some food or drink for a set period of time. While more traditional forms of fasting might last anywhere from 24 to 72 hours, intermittent fasting involves cycling between periods of eating and fasting for a few hours or a couple of days of very limited caloric intake. This form of fasting has seen a recent surge in popularity due to its various health benefits.

What Happens in your Body in the Fasting Month?

Does When You Eat Matter?

What you eat matters. Many studies have shown that the types of food you eat affect your health. But what about the timing? Scientists are just 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 technologylike refrigeration, transportation, and electric lightinghave made food more readily available.

This 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. Researchers have started looking at whether fasting can have potential benefits for some people.

Could Help Lower Cholesterol

Your cholesterol might also improve after intermittent fasting when consuming a healthy diet during your non-fasting periods.;

Better lipid profiles have been found after intermittent fasting including lower overall cholesterol, lower LDL , and lower triglyceride levels in healthy and overweight populations .

The majority of studies investigating intermittent fasting’s effects on cholesterol have focused on those fasting for Ramadan, so intermittent fasting may be an effective dietary method to improve your cholesterol, but further studies are needed to explore the differences in short-term vs long-term metabolic changes associated with fasting. .;

If you’re concerned about high cholesterol try adopting healthy lifestyle habits like incorporating exercise and a diet low in saturated and trans fats, and rich in high fiber foods.;

Does Fasting Burn Muscle

So the main question is this if you fast for long enough, doesnt your body start to burn muscle in excess of what it was doing previously in order to produce glucose for the body. No.

Lets look carefully at this graph by Dr. Kevin Hall from the NIH in the book Comparative Physiology of Fasting, Starvation, and Food Limitation. This is a graph of where the energy to power our bodies comes from, from the start of fasting. At time zero, you can see that there is a mix of energy coming from carbs, fat, and protein. Within the first day or so of fasting, you can see that the body initially starts by burning carbs for energy. However, the body has a limited ability to store sugar. So, after the first day, fat burning starts.

What happens to body protein? Well, the amount of protein your body turns over goes down. There is certainly a baseline low level of protein turnover, but my point is that we do not start ramping up internal protein consumption. We dont start burning muscle, we start conserving muscle, because protein turnover is reduced, but not no, it is not zero.

What Is A Bone Broth Fast

A bone broth fast;combines the health benefits;of short-term or intermittent fasting;with those of drinking bone brothwhich often results in both short- and long-term;benefits, such as increased energy, better digestion, weight loss, a faster metabolism, clearer and brighter looking skin, and more restful sleep. Similar to a water fast, a bone broth fast;involves taking a break from solid foods and consuming liquids throughout the day. But during a bone broth fast, instead of drinking only herbal tea;and water, you drink several cups of bone broth;throughout the day .

One of the key benefits of a bone broth fast; is that it allows you to consistently take in plenty of essential nutrients, electrolytes, and protein. This prevents you from becoming dehydrated and helps keep your energy levels up, while the protein from the collagen and gelatin;keeps your appetite satisfied. And you can probably agree that youre most likely to stick to a fast when it doesnt leave you feeling starved, light-headed, or deprived.

The Math Behind Fasting

OMAD Diet: What Happens to Your Body When You Fast for 23 Hours a Day?

What time frame triggers this calorie-restricted signal to the body? An earlier analysis of intermittent fasting in the New England Journal of Medicinefound that fitting meals into six-or eight-hour windows is beneficial in reducing inflammation compared with a typical day of eating, but a 12-hour window is less so, says Mark Mattson, Ph.D., a coauthor of the study.

But you do reap some benefits without being at the more restrictive end, says , a sports dietitian and the lead author of Nutrition for Sport, Exercise, and Health. “Short-term studies using time-restricted eating, where food is restricted to 13-hour windows or less , show it can help decrease inflammation.”

What Nine Days Of Fasting Does To Your Body And Brain

What happened when we sent Esquires gluttonous food editor to a German health clinic for a fast, with instructions to keep a hunger diary? Put down your knives and forks and get ready for an unexpected epiphany

It seemed like a good idea at the time. Like most things do, in the soft, dying light of an epic Friday lunch, fuelled by boozy optimism and three-bottle bravado. I heard about this place, I say to the editor, a health clinic in Germany, where you go without food for days on end. Weeks even. You know, Jesus and his jaunt to the desert. And Gandhi. A physical form of prayer. Brings you closer to God and all that.

He raises an eyebrow and takes another glug of wine: And what, may I ask, has increased spiritual awareness through physical deprivation got to do with you?

Good point. But like a slack-bellied Bear Grylls, Ive come prepared. Well, you know me, your indolent, sybaritic, exercise-averse food editor who makes those Lotus Eaters look like the Temperance League on starvation Sunday. He nods.

And you know how I hate all that New Age bullshit about wellness; and those homeopathic quacks, and the bastard snake oil salesmen sugar-coating dodgy diets and miracle cures in a shiny glaze of quasi-scientific claptrap. He nods again, and rolls his eyes.

Well, throw in some Tibetan bloody bowls, a few leeches, plus tubes jammed up your arse, and what do you get? By the look on his face, a mental image that puts him off his pudding. But still.

Fasting Might Protect The Brain

Researchers have also looked into connections between caloric restriction and brain function.;Mark Mattson, PhD, chief of the Laboratory of Neurosciences at the National Institute on Aging in Baltimore, co-authored a;review published in February 2014 in the journal Cell Metabolism;with Longo, which concluded there was convincing evidence in animal studies that intermittent-fasting diets were linked to less neuronal dysfunction and degeneration, as well as fewer clinical symptoms of Alzheimers disease, Parkinsons disease, and Huntingtons disease in the rodents in those studies.

Again, the same conclusions have not yet been proven in people, but Dr.;Mattson and Longo conclude its an important opportunity for more research.

One explanation is that during periods of fasting and exercise certain brain activity actually increases, as does blood flow in certain areas, helping protect the brain from all of these other problems. That theory is supported by multiple brain imaging studies in people, Mattson explains in another review article published in December 2012 in the journal Cell Metabolism.

How Much Water You Should Drink To Lose Weight Fast

During stage three, your body starts to enter into a healing mode. This healing process begins as your digestive system takes a rest from the common stressors and toxins it endures on a daily basis. As a result, your body has fewer free radicals entering the mix, and oxidative stress decreases.

On the flip side, fasting causes a stress that provides an added benefit. This is a kind of mild stress that is comparable to the stress caused by exercise, which ultimately makes you stronger and your immune system more resilient.

How To Break A Fast

We almost forgot about the last and perhaps most important stage of intermittent fasting the refeeding stage! Its important to break your fast with a nutritious, balanced meal that will further improve the function of cells and tissues that went through cleanup while you were fasting. From :

Upon refeeding, ingested carbohydrates* and glucose stimulate release into the blood of the incretin hormone glucagon-like peptide 1 from enteroendocrine cells in the gut. GLP1 enhances clearance of glucose from the blood by stimulating insulin release from the pancreas and increases the insulin sensitivity of cells. GLP1 crosses the bloodbrain barrier and can act directly on neurons to promote synaptic plasticity, enhance cognition and bolster cellular stress resistance.

*Update: This isnt a recommendation to break your fast with lots of carbs and sugars, which may in fact lead to problematic blood sugar spikes. A few carbs can go a long way. Its best to break your fast with a balanced meal including plenty of vegetables, plant fibers and plant fats, with healthy proteins and some whole grains or legumes if you choose. Avoid simple sugars and processed/packaged foods. Learn what works best for your body, and what you feel best eating following your fasts.

Medical Reasons For Fasting

Another topic on which there is medical agreement is the benefit – actually, the necessity — of fasting before surgery.

“You don’t want the body to be digesting food as it manages the slower breathing under anesthesia,” says Fernstrom.

Fasting is also required to get accurate readings for certain medical tests. Short-term fasting before tests for cholesterol and blood sugar levels, for example, helps achieve a more accurate baseline count.

Fasting Diets Havent Been Linked To Health Problems If Followed Safely At Least Not Yet

While the research suggests fasting can help a number of diseases from;multiple sclerosis;to allergies doctors say that if youre medically able to fast safely , there’s no research against doing it, either. “If youre not on prescription medicine, generally in good health, and want to fast periodically because you feel you get a health benefit from it, we don’t have evidence that this would be harmful,” Katz says.

A review article published in March 2017 in the journal Behavioral Sciences concluded that there were no clear harms linked to intermittent fasting diets, according to studies on the topic. Still the authors of that review also note that long-term data on the safety of intermittent fasting hasnt been collected yet, so how such diets affect people over the long-term is yet to be determined.

Fasting Gets Your Insulin Sensitivity Back On Track

One of the keys to managing your weight is, no surprise, managing your insulin levels. Fasting has repeatedly been shown to produce a positive effect on insulin sensitivity, which is the bodys ability to tolerate carbohydrates better.

Insulin is a fat-storage hormone secreted from the pancreas. It lets your body use glucose from your blood as fuel. After we eat a meal, your blood sugar levels will spike. This will send a message to the pancreas to release insulin. The insulin attaches itself to the cells and allows the cells to absorb sugar for energy.

Obese individuals tend to have poor insulin sensitivity, leading to an increase in fat being stored.

Fasting has been shown to raise the levels of specific proteins; which help to improve insulin sensitivity and reduce overall fat storage.

May Be Beneficial For Heart Health

Heart disease is currently the worlds biggest killer .

Its known that various health markers are associated with either an increased or decreased risk of heart disease.

Intermittent fasting has been shown to improve numerous different risk factors, including:

  • blood sugar levels

The effects of fasting on heart health need to be studied more in-depth in humans before recommendations can be made.


Studies show that intermittent fasting can improve numerous risk factors for heart disease, such as blood pressure, cholesterol levels, triglycerides, and inflammatory markers.
