12 Extraordinary Health Benefits
Associated with Intermittent Fasting

The science is in. Mounting scientific evidence supports the health benefits derived from following a plan of intermittent fasting. Here are 12 of the benefits that have the most scientific support:

  1. Promotes Weight and Fat Loss

    Intermittent fasting can help you lose weight and belly fat, without having to consciously restrict calories. Intermittent fasting also amplifies enzymatic fat breakdown (lipolysis).

  2. Reduces Insulin Resistance

    Intermittent fasting can sensitize cells to insulin, reducing harmful insulin resistance and lowering blood sugar by 3 to 6 percent. Fasting insulin levels have been lowered by 20- 31% with intermittent fasting, all of which protect against type 2 diabetes.

    Insulin secretion from the pancreas goes up due to an increase and regeneration of the beta cells of the pancreas (the cells that produce and secrete insulin).

  3. Regulates Blood Sugar

    When your blood sugar is constantly high, your insulin levels are constantly high. This leads to type 2 diabetes, which is a huge epidemic. Consistently high blood sugar levels (also known as hyperglycemia) cause damage to the insides of the arteries.

    Hyperglycemia harms the vessels that supply blood to vital organs, which can increase the risk of heart disease and stroke, kidney disease, vision problems, and nerve problems.

  4. Reduces Inflammation

    Research shows that a program of intermittent fasting reduces blood markers of inflammation, a key driver of many chronic diseases. Oxidative stress is one of the factors that accelerates aging and predisposes you to developing disease.

    Several studies show that intermittent fasting boosts the body's resistance to oxidative stress. Intermittent fasting strengthens immune function and enhances the body's ability to repair cells and DNA.

  5. Promotes Cardiovascular Health

    Intermittent fasting improves multiple indicators of cardiovascular health in both overweight and normal weight individuals.

    Intermittent fasting reduces the following risk factors for heart disease — the leading cause of death in American men and women:

    • Resting heart rate
    • Blood pressure
    • Bad LDL cholesterol
    • Blood triglycerides
    • Inflammation
    • Blood sugar
    • Insulin resistance

    In addition, intermittent fasting lowers inflammation and oxidative stress, both causative factors associated with heart disease.

  6. Prevents and Treats Cancer

    Some research suggests that intermittent fasting helps fight cancer by lowering insulin resistance and levels of inflammation. Intermittent fasting may also reverse the effects of chronic conditions such as obesity and type 2 diabetes, which are both risk factors for cancer.

    Researchers believe that intermittent fasting suppresses tumor growth and extends survival in patients with cancer. Intermittent fasting may make cancer cells more responsive to chemotherapy while protecting other cells.

    Intermittent fasting also boosts the immune system to help fight cancer that is already present.

  7. Promotes Brain Health

    Intermittent fasting increases production of brain-derived neurotrophic (BDNF), an anti-aging protein thought to protect against Alzheimer's disease by helping the brain produce new healthy cells and strengthen existing ones, improving cognition.

    Intermittent fasting causes the cells in the body to initiate the cellular cleanup process called autophagy.

  8. Promotes Psychological Benefits

    Intermittent fasting improves eating behavior and mood. Intermittent fasting increases BDNF, the protein that aids in the growth of new nerve cells.

    A deficiency of BDNF has been implicated in depression and various other brain problems. BDNF is food for the brain cells, keeping them flourishing, strong and healthy.

  9. Treats Asthmatics and Multiple Sclerosis

    With weight loss comes improvement in asthma symptoms and a reduction in airway resistance. Multiple Sclerosis (MS) is an autoimmune disorder characterized by degeneration of the nervous system.

    Recent studies in people with MS adhering to intermittent fasting programs saw reduced symptoms in as short a period as two months.

  10. Fights Aging

    Intermittent fasting can extend lifespan in rodents. Studies showed that fasted mice lived 36-83% longer! Although it's a far cry from mice to men, intermittent fasting has become very popular among the anti-aging crowd.

    The health benefits of intermittent fasting on aging, oxidative stress, metabolism, and cardiovascular disease have been demonstrated in both human and animal studies alike.

  11. Promotes a Healthy Gut

    The gut microbiome refers to all the microbes in your intestines, which act as another organ, crucial for your health. More than 1,000 species of bacteria are in the human gut microbiome, and each of them plays a different role in your body. Most of them are extremely important for your health, whereas others may cause disease such inflammatory bowel disease, liver cirrhosis, and colorectal cancer.

    Scientific research has shown that intermittent fasting restores microbe health and diversity in the gut by increasing the good microbes, augmenting tolerance against bad gut microbes, and rebuilding the integrity of the intestinal wall.

  12. Regulates Sleep

    Experts have recommended that adults get about seven to nine hours of sleep per night for good health. Intermittent fasting positively affects your circadian clock, which exerts a powerful influence over your sleep. Intermittent fasting strengthens the 24-hour circadian clock.

    A stronger, more synchronized circadian clock means an easier time falling asleep, staying asleep, and waking feeling refreshed on a regular basis.

    A good night's sleep will help you function at your best, and to protect your health over time, and with age.

12 Questions & Answers on
Intermittent Fasting with Dr. Janet

Intermittent fasting is one of the world's most popular health and fitness trends. Since intermittent fasting is a relatively a new phenomenon, you may have a host of questions that you want answered to help you determine whether intermittent fasting is right for you.

Here are some common questions and answers to help you make that decision:

  1. What is intermittent fasting?

    Intermittent fasting is an eating pattern that cycles between periods of short-term fasting and eating. There are multiple intermittent fasting diet plans circulating. All of them dictate when you should eat rather than what specific foods you should eat.

    One popular version, called the 16:8 method, means you fast for 16 hours every day and eat during your chosen 8 hour eating window. You repeat this pattern of eating every day. However, for long-term health benefits, it is highly recommended that you don't ignore the "what to eat" part of this eating regimen.

    As a nutritionist, it is suggested that you combine a plant-based, Mediterranean style of eating with your intermittent fasting plan of choice.

  2. How many varieties of intermittent fasting plans are there?

    There are several different ways of doing intermittent fasting such as the 16:8 method and the 5:2 diet. The top 5 of the most popular plans are outlined in my book.

  3. What are the benefits of following an intermittent fasting program?

    Numerous scientific studies have shown that intermittent fasting programs can have powerful benefits for your body and brain.

    Here are just a few of the notable health benefits:

    • Promoting weight loss (especially loss of stubborn belly fat)
    • Reducing insulin resistance and lowering blood sugar levels
    • Boosting metabolic rate
    • Improving numerous risk factors for heart disease such as blood pressure, cholesterol levels, triglycerides and inflammatory markers
    • Fighting aging and boosting mental acuity
  4. Is intermittent fasting safe?

    Intermittent fasting is safe for most people, but it's not for everyone. If you have a medical condition, you must get medical clearance to follow a program of intermittent fasting, especially if you have:

    • Diabetes or problems with blood sugar regulation
    • Have high or low blood pressure
    • Take prescription medications (people who take medications for blood pressure or heart disease may be more prone to electrolyte abnormalities from fasting
    • Are underweight

    Intermittent fasting should NOT be practiced by:

    • Children
    • People with a history of eating disorders
    • Women who are trying to conceive
    • Women who are pregnant or breastfeeding
    • Uncontrolled diabetics
  5. Is hunger hard to deal with when practicing intermittent fasting?

    In the beginning, you'll feel hunger pangs during your fasting periods. Most intermittent fasting newbies figure out how to accept, adjust, and dull hunger pangs, which typically dissipate after about a month on an intermittent fasting program.

  6. Do you have to exercise when practicing intermittent fasting?

    Yes, but no marathons are required! All Americans need to move more for better health. Because you're entering into a lifestyle program aimed at improving your health, this one does indeed advocate daily exercise.

  7. How long should you fast for?

    You'll see health benefits from fasts of from 14 hours to 36 hours. The ideal fasting window and ultimately fasting regimen will vary depending on you. What matters is the duration of fasting that works for your lifestyle.

  8. Can you drink alcohol when practicing intermittent fasting?

    Yes, you can during your eating windows, in moderation, and if you can drink responsibly. You should know that drinking any amount of alcohol increases your risk of seven different types of cancer.

  9. Can you have a cheat day during intermittent fasting?

    One of the phenomenal attractions of intermittent fasting is the concept that you get lots of cheat days - built in. Technically, you can eat whatever you want during your eating windows. This simple idea of freedom in eating is very motivating — fast today for tomorrow you feast!

  10. Can you gain muscle when practicing intermittent fasting?

    Yes, studies have shown that combining intermittent fasting with a program of strength-training designed to increase muscle mass will result in muscle gain and fat loss.

  11. Can you take medications and supplements when practicing intermittent fasting?

    Yes, you must continue taking your prescription medications as directed (and should only practice intermittent fasting under the guidance of your personal healthcare provider).

    If you need to take your meds with food, on a daily basis, choose an intermittent fasting plan that allows a daily window of eating for your medications.

    Supplements, if they contain negligible calories, can be taken as usual. Check with your healthcare provider if you have any concerns.

  12. How long can you stay on a program of intermittent fasting?

    If you are eating nutritious food and can maintain a healthy weight, you can eat this way indefinitely.

Exercise during a fast can be tricky, and the book covers when and how to do it. This book offers lots of great tips for intermittent periods of "feasting" and "fasting" and outlines several different safe-and-easy intermittent fasting plans to suit your needs.

Great Introduction To Intermittent Fasting

Dr. Brill starts out by explaining the different types of fasting. Next, she goes over the information needed to use this plan to lose weight, including calculating ideal weight, calories, and BMI. If a reader is more interested in the health aspect, as I was, he/she is advised to skip ahead. According to studies, intermittent fasting can dramatically affect health, cells, and hormones. The author eschews the popular keto diet, declaring it inappropriate to combine with intermediate fasting, and touting instead the Mediterranean eating plan. Dr. Brill also goes over some basic nutrition facts, and includes recipes.
