The body needs a steady fuel supply to function. It is vital for both mental and physical work. Fasting, I thought, was for religious reasons or political protest. I become unpleasant when I’m hungry. There’s even a term for it: “hangry”!
Yet, given the rising interest in fasting, I examined its risks and benefits. Popular fasting methods range from consuming few or no calories every other day to fasting for 16 hours or more each day.
For example, a friend in his early 50s lost 12 pounds in about two months by following what he calls the 7-11 diet. He eats nothing from 7 p.m. until 11 a.m. the next morning every day.
If you’re thinking about intermittent fasting, stay hydrated. Eat healthy foods in your eating window. Enjoy whole grains, healthy fats, and proteins, and avoid sugar and refined carbohydrates. As Dr. Mattson suggests, decrease your eating window over four months to adjust.
Intermittent fasting can help you. But it’s important to find a routine that works for you. It should not cause stress or bad side effects. Listen to your body if you’re fasting for health, weight, or longevity. It’s vital to adjust as needed.

Insights from Neuroscientist Mark P. Mattson
I was skeptical, but I must praise a long, 16-hour fast. Mark P. Mattson is a neuroscientist. He works at the National Institute on Aging and Johns Hopkins University. He said the liver stores glucose, which the body uses for energy before burning body fat.
“Using up the liver’s calories takes 10 to 12 hours. Then, a metabolic shift occurs to using stored fat,” Dr. Mattson told me. After meals, glucose is used for energy, and fat is stored. During fasts, once glucose is gone, fat is broken down and used for energy.
He said most people trying to lose weight should aim for 16 calorie-free hours. “The easiest way to do this is to stop eating by 8 p.m., skip breakfast, and then eat at noon,” he added.” (Caffeine-dependent people can have sugar-free black coffee or tea before lunch.) But expect to wait to see results; he said it can take up to four weeks to notice an effect.
Dr. Mattson and his colleague Rafael de Cabo at the Aging Institute recently reviewed the effects of intermittent fasting on health, aging, and disease in The New England Journal of Medicine.
Their article was prompted by patients asking doctors about the effects of fasting. Dr. Mattson said that many doctors lack nutrition knowledge. They need help advising patients.
Evolutionary Insights and Health Benefits from Animal and Human Studies
Several recent studies have examined intermittent fasting in people, but none are long-term. Most disease-related findings come from research on lab animals. In a stroke animal model, those fed intermittently had less brain damage. They better resist the stress of low oxygen and energy.
Research shows that intermittent fasting can improve health. It may help with chronic issues like obesity, diabetes, and cancer. It may help with heart and brain diseases, too.
Animal Studies:
- Animal studies reveal that intermittent fasting can positively change diseases.
- It improves health and slows or reverses aging and disease.
Human Studies:
- Human studies found improvements in insulin resistance, blood fats, and blood pressure. They also found less inflammation.
- In a 2018 study, patients with many sclerosis saw symptom reduction in two months.
Evolutionary Perspective:
- Predators often fast while hunting, which helps them recover from injuries.
- Our ancestors survived feast-or-famine conditions thanks to fasting.
Modern Findings:
- Researchers note that our ancestors didn’t eat three large meals and snacks daily. They also didn’t lead sedentary lives.
- Studies show that most organ systems adapt to intermittent fasting. It helps the body manage challenges and return to normal.
We can find benefits for modern health in intermittent fasting. Its roots are in evolution and science.
Safety and Practicality of Intermittent Fasting
Dr. Mattson explained that during a fast, the body makes few new proteins. Cells take protein from nonessential sources. They break it down and use the amino acids to make new essential proteins for survival. Then, after eating, many new proteins are produced in the brain and elsewhere.
A reasonable question might be, “How safe is intermittent fasting?” When the body uses fats for energy, it produces ketone bodies. The researchers said they control many proteins and molecules. They affect health and aging.” Ketosis is a build-up of acidic ketones in the blood. The Atkins diet, the ketogenic diet, and other low-carb diets aim to achieve it. Extreme ketosis can harm the liver, kidneys, and brain. It is especially dangerous for people with chronic conditions like diabetes and heart disease.
Another critical question: “How practical is intermittent fasting?” Not much, especially in its early weeks or for those with little control over their mealtimes.
The researchers wrote that many will feel hungry and irritable, and food restrictions will also make it hard to concentrate. They added that these side effects usually disappear within a month.
Eating restrictions like intermittent fasting can be very limiting. If your fasting window starts at 7 p.m., how do you respond to a dinner invitation?
Personal Experiences and Dietary Advice
Fasting can trigger eating disorders in those at risk. I found this in my early 20s. In trying to control my weight, I ate little all day. But, once I ate in the evening, I couldn’t stop. I ended up with binge eating disorder.
This diet’s success may depend on your pre-diet snacks and drinks. It also depends on the foods you eat during non-fasting hours. Some may binge on anything during the eating window. It may be low in nutrition. They do this because they know they cannot eat for a set time.
Dr. Mattson cautioned intermittent dieters to “eat healthy foods. Include whole grains, healthy fats, and protein. Limit saturated fats. Avoid sugar and refined carbs.” “On fasting days, be sure to stay well-hydrated.” Dr. Mattson suggests easing into intermittent fasting over four months. First, reduce your daily eating hours. Then, increase your fasting days each week. Additionally, reduce the amount of calories you consume on fasting days. This approach allows your body to adjust to the changes.
