How Does Intermittent Fasting Affect Fat

Intermittent Fasting Science (BEST Fat Loss Diet?) Healthy Good or Bad for Weight Loss & Muscle Gain

Short answer: thereâs more to find out before we know for sure. A review of studies on intermittent fasting from 2015 found that mice eating on an alternate day schedule did have a reduction in visceral fat. However, in the human studies reviewed, the effects of intermittent fasting on fat were not as straightforward â because they mostly paired calorie restriction with intermittent fasting. Meanwhile, a 2019 review did find modest reductions in fat mass and weight circumference in humans.

In the new Cell Reports mouse study, researchers found different fat types actually adapted to intermittent fasting. During fasting, fat tissues can provide energy to the rest of the body by releasing fatty acids in a process called lipolysis. Mouse visceral fat, however, became resistant to this process during intermittent fasting, as opposed to the mice with unlimited access to food.

âDifferent fat depots around the body can adapt and respond differently to intermittent fasting.â

The study also suggests intermittent fasting caused fatty acid synthesis enzymes to increase in both fats, suggesting both subcutaneous and visceral fat began to store more fat ahead of the alternate-day fasting period.

, the senior author of the study and a senior lecturer in the School of Life and Environmental Sciences at the University of Sydney, tells Inverse this data suggests âdifferent fat depots around the body can adapt and respond differently to intermittent fasting.â

Intermittent Fasting Can Be Hard But Maybe It Doesnt Have To Be

Initial human studies that compared fasting every other day to eating less every day showed that both worked about equally for weight loss, though people struggled with the fasting days. So, I had written off IF as no better or worse than simply eating less, only far more uncomfortable. My advice was to just stick with the sensible, , diet.

New research is suggesting that not all IF approaches are the same, and some are actually very reasonable, effective, and sustainable, especially when combined with a nutritious plant-based diet. So Im prepared to take my lumps on this one .

We have evolved to be in sync with the day/night cycle, i.e., a circadian rhythm. Our metabolism has adapted to daytime food, nighttime sleep. Nighttime eating is well associated with a higher risk of obesity, as well as .

Based on this, researchers from the University of Alabama conducted a study with a small group of obese men with prediabetes. They compared a form of intermittent fasting called “early time-restricted feeding,” where all meals were fit into an early eight-hour period of the day ,or spread out over 12 hours . Both groups maintained their weight but after five weeks, the eight-hours group had dramatically lower insulin levels and significantly improved insulin sensitivity, as well as significantly lower blood pressure. The best part? The eight-hours group also had significantly decreased appetite. They werent starving.

May Help Manage Inflammation

Our bodies naturally undergo inflammation as a part of the process it uses to fight off harmful pathogens or recover from injuries by triggering our immune system.

However, when inflammation persists for too long it can start causing us harm. Chronic inflammation happens when the immune system continues to be triggered by what it thinks is a threat. Prolonged inflammation plays a role in the development of chronic health conditions such as atherosclerosis, heart disease, osteoporosis, and even diabetes .

Intermittent fasting has been shown to reduce concentrations of pro-inflammatory markers such as homocysteine, interleukin 6, and C-reactive protein which play a role in the development of these chronic diseases .

Eating a diet rich in anti-inflammatory foods or following a strict anti-inflammatory diet or auto-immune protocol may also help reduce inflammation in the body.

Although fasting may provide some health benefits, looking at the quality of our diet and lifestyle can help us create healthy habits to support our health.

Intermittent Fasting For Treating Obesity: Is It Superior To Daily Caloric Restriction

A systematic review searching for human trials published from January 1, 2000 to July 1, 2019 focusing on IF for weight loss, found only 18 small RCTs and 9 trials without active controls :117-25.). In this study, the average reduction in body mass index was 4.3%, with weight losses ranging from 0.8% to 13%, and a high grade of heterogeneity. Still, it concluded that it was not possible to directly compare IF with other strategies of caloric restriction. Some of the most relevant studies will be discussed below.

Wilkinson and cols. performed a trial in which individuals who had a mean eating interval of 15.13 hours per day, reduced it to a mean of 10.78 h for 12 weeks :92-104.e5.). The individuals baseline status was used as the control, and the results showed a mean of 3.3 kg weight loss and a decrease in fat mass, LDL-cholesterol and non-HDL-cholesterol, blood pressure, and alterations of other metabolic factors. This was a single-arm study, and though mixed linear models suggested that metabolic improvements were not attributed to changes in weight, the lack of a control arm prevents a definite conclusion :92-104.e5.).

If You Need To Lose Weight A Diet That Focuses Mainly On When You Eat May Be A Good Way To Shed Pounds And Improve Your Cardiovascular Health

Is Intermittent Fasting Good for Weight Loss?

Anyone who’s tried different weight-lossdiets is probably familiar with their pitfalls. Low-calorie diets often leave you tired, hungry, and cranky. Low-carb or “keto” diets can cause cravings and constipation. Low-fat diets are also tough to follow and, contrary to popular belief, they do not seem to prevent cardiovascular disease.

Another diet trend, intermittent fasting, takes a different approach. Rather than limiting what you eat, this diet limits when you eat . For some people, that change may be easier to manage, says Dr. Eric Rimm, professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health.

Short-term studies suggest that people stick to intermittent fasting diets as well as or better than they do to other diets. And according to a 2019 review article in the journal Nutrients, intermittent fasting promotes weight loss and may reduce risk factors linked to heart disease, including diabetes, high blood pressure, unhealthy blood lipid levels, and inflammation.

“However, we don’t have much evidence about how well this diet works over the long term,” says Dr. Rimm, noting that there are just two long-term studies of intermittent fasting, each lasting a year. Nor are there large populations of people who’ve followed this eating pattern for years. That’s in contrast to two other diets linked to a healthy heart and healthy body size the Mediterranean diet and a vegetarian diet.

Could Help Promote Balance In Other Areas Beyond Food

When we think of intermittent fasting we immediately think of food, since that is what we are limiting. But could we benefit from taking a break from other things in our life?

The basic concept of fasting is to abstain from something for a specific period of time, so what other things could we fast besides food?

Television, social media, and video games to name a few may all be things we could use a break from that may positively impact our health and well-being.

At the end of the day, consciously choosing to reduce or shift our habits can help us create health and wellness goals based on our values and beliefs.

Additional Benefits From Intermittent Fasting

Many of the cited mechanisms of IF on animal models are related to the improvement of chronic conditions much beyond obesity itself.

The longer study performed evaluating IF for T2D to date , did not observe superiority of IF, regarding HbA1c or weight loss :e180756.). In this context, IF regimens can be considered and individualized in patients with T2D, but similar to what was already discussed in obesity, it should be clear that it is an alternative to daily caloric restriction, rather than a superior intervention.

de Cabo and Mattson provided a very compelling and complete discussion of additional promising benefits of IF in cancer, aging, neuroprotection, and more :2541-51.). However, it is important to note that most of the available data discussed by de Cabo and Mattson come from caloric restriction experiments in animal models :2541-51.). Whilst in those models, caloric restriction is achieved through a TRF , it is not possible to conclude whether benefits are from fasting, caloric restriction, or both. Human studies are just emerging.

Results from trials are heterogeneous, and due to that, a personalized approach is necessary. The search for clinical markers able to predict responses is appealing. As most trials are small, many discussed results should be interpreted cautiously. Lack of statistical power to show differences in weight loss and substitutive markers is one crucial factor that should be considered when evaluating IF RCTs.

How Much Weight You Can Lose With Intermittent Fasting

Is Intermittent Fasting Good For Weight Loss
  • When fasting two days per week, you can expect to lose between 9 and 13 pounds in the first 2 to 3 months, says Leonie Heilbronn, an associate professor at Adelaide Medical School.
  • When fasting three days per week, Heilbronn says you could lose 13 to 18 pounds in the first 2 to 3 months.

Ultimately, when deciding if intermittent fasting is right for your weight loss goals, it’s crucial to keep your lifestyle and eating habits in mind.

“Some people can struggle with not eating for prolonged periods,” says Heilbronn.

Intermittent Fasting Food List: How To Choose The Best Foods

Eating during intermittent fasting is more about being healthy than just rapidly losing your weight. Thus, it is critically important to choose nutrient-dense foods such as veggies, fruits, lean proteins, and healthy fats.

The intermittent fasting food list should contain:

1. For Protein

The Recommended Dietary Allowance for protein is 0.8 grams of protein per kilogram of body weight. Your requirements may vary depending on your fitness goals and level of activity.

Protein helps you lose weight by decreasing energy intake, increasing satiety, and boosting metabolism.

Besides, when combined with strength training, increased protein intake helps build muscle. Having more muscle in the body naturally increases your metabolism, as muscle burns more calories than fat.

A recent study suggests that having more muscle in your legs can help reduce belly fat formation in healthy men.

The IF food list for protein include:

  • Poultry and fish
  • Dairy products such as milk, yogurt, and cheese
  • Seeds and nuts
  • Whole grains

2. For Carbs

According to the Dietary Guidelines for Americans, 45 to 65 percent of your daily calories should come from carbohydrates .

Carbs are the major source of energy for your body. The other two are protein and fat. Carbs come in various forms. The most notable of them are sugar, fiber, and starch.

Make sure to choose foods that are high in fiber and starch but low in sugar.

The IF food list for carbs include:

  • Sweet potatoes
  • Chickpeas

3. For Fats

  • Avocados

May Increase Your Life Span

There are several reasons that intermittent fasting may positively impact our life span weight loss, decreased blood pressure, and most of the benefits we listed above may all contribute to prolonging our life while also increase our quality of life at the same time.

Intermittent fasting has been found to affect longevity in animal studies, having beneficial effects on life span and markets for health, stress, metabolic response, and age-related diseases .

These findings are hard to confirm in human trials as there are many factors that affect epidemiological studies and many different types of fasting. But at the end of the day, some of the benefits of intermittent fasting may increase our quality of life overall and reduce our risk of developing chronic diseases.

Intermittent Fasting Helps You Lose Actual Fat Unlike Most Diets

When someone says they want to lose weight, they actually mean they want to lose body fat.

Ideally you dont want to lose muscle mass, nor do you want to lose much water . This type of weight loss does not reduce fat stores and serves no good purpose.

Research indicates that fasting helps you lose more fat mass and less muscle mass or water weight than very low calorie diets or weight loss cleanses and detoxes.

This review study found that intermittent fasting helped people cut 4-7% from their waist circumference over a period of 24 weeks. That means they lost actual belly fat, which is the harmful fat around the organs .

These findings are in line with a more recent review study that looked at all the current evidence.

The researchers found that compared to following a very low calorie diet a type of intermittent fasting called alternate day fasting caused an average of 8.4 lb extra fat loss .

Summary: When you lose weight, you want it t come from fat stores and not muscle or water. Research indicates that intermittent fasting causes more fat loss than a very low calorie diet.

Intermittent Fasting For Weight Loss: Everything You Need ...

You’ve probably heard aboutor even experimented withintermittent fasting , which can promote a slew of health benefits, including disease prevention and weight loss.

Still, you may not be clued into one nuance of intermittent fasting that can help make it both incredibly beneficial and easier to embrace: harnessing your intuition to guide your eating patterns.

In his new book Intuitive Fasting, Dr. Will Cole, a leading function-medicine expert, maps out a four-week plan for resetting your hunger signals and recharging your metabolism by trading prescribed eating times for ones that innately work for you. “The truth is, most of us have been following an artificially constructed schedule that does not reflect our bodies’ natural and most optimal eating schedule,” says Dr. Cole. “In fact, eating three meals every day can cause metabolic inflexibility, which can easily lead to inflammation, weight gain, fatigue, and chronic health problems.

So, how does intuitive fasting help you shed unhealthy excess weight? “When blood sugar is balanced, satiety signaling is improved and metabolism is more stable, enabling us to eat and gently fast intuitively,” says Dr. Cole. “By being in touch with your body, you have greater agency over how, when, and what you eat, instead of food controlling you.”

What follows are a few more pointers for tapping into your biological cues to support healthy weight loss:

Typical Fasting Weight Loss Plans

Fasting regimens vary, but the basic premise usually starts with a strict regimen allowing only water, juice and/or some kind of laxative concoction. Some plans allow a few solid foods, but are still called fasts because they provide so few calories.

Not all fasts are created equal. Some can be perfectly safe, such as medical fasts supervised by a physician. Religious and cultural fasts are typically undertaken as an act of devotion, last from 24-48 hours, and are not intended to promote weight loss.

Fasts lasting a day or two are unlikely to be dangerous for most healthy adults. But high-risk people, the elderly, anyone with a chronic disease, pregnant women, and children are advised against any type of fasting.

The real danger lies in staying on the fast for prolonged periods, anywhere from three days to a month.

How Intermittent Fasting Helps With Weight Loss

Studies show that intermittent fasting and weight loss are closely tied, but that is not all intermittent fasting does. Below is a summary of the benefits of intermittent fasting for weight loss, along with an explanation of how it helps you lower your body fat percentage.

  • Through metabolic switching, when your body breaks down stored fat for energy.
  • Optimizes the release of fat-burning hormones in your body, such as insulin and HGH, which greatly aids weight loss.
  • Keeps your insulin levels steady, helping you lose extra fat, and also maintains your body weight.
  • Helps combat health problems such as diabetes, obesity, and other chronic illnesses.
  • Maintains a fat-burning state in your body, giving you more energy throughout the day.
  • Helps reduce hunger pangs and cravings over time.
  • Balances your blood levels and controls other essential hormonal levels.
