Fast. What Can It Do For You?

Promote weight loss

Research shows that no matter how you fast, you are likely to lose some weight during the fast. But even better, fasting also eliminates belly fat. Carrying too much weight in the middle increases your risk of heart disease, so losing that weight can improve your health.

Lower blood pressure

The science on the positive effects of fasting on your blood pressure is pretty sound. When you stick with it for a long time, you will see your blood pressure drop. But once you stop, your reading goes back to where it was before you started.

Reduce inflammation

Small proteins called inflammatory cytokines kick-start the inflammatory process in your body. Studies of men and women who fasted during the Muslim holy month of Ramadan showed that the amount of these proteins dropped after three weeks of fasting. Similar studies in adults with asthma have shown similar results. Fasting improves symptoms and lung function.

Lower cholesterol

There is no conclusive evidence, but small studies have shown that fasting — especially on alternate days or alternate days — can reduce Low-density lipoprotein. That’s the type that can build up in your arteries. Fasting does not seem to affect high-density lipoprotein cholesterol.

Improve brain function

So far, much of the information about fasting and brain function has come from non-human studies. Studies in fasting rats have shown improvements in brain structure and growth of nerve cells that improve brain function. Experts are studying how this could help slow diseases such as Alzheimer’s and Parkinson’s.

Cut the risk of cancer

Animal and cellular studies have shown that fasting may help stop tumor growth and help chemotherapy work better in cancer patients. There is not enough research in humans to know how fasting affects a person’s cancer risk.

Improve insulin resistance

Recent studies in insulin-resistant people have shown that fasting improves the way insulin works in the body. The research is still ongoing.

Better Sleep

The jury is still out on how fasting affects your shut-eye. Some studies say it can reduce the amount of rapid eye movement (REM) sleep, during which you dream and your brain puts memories together. Other studies have shown that fasting may raise levels of chemicals that make you feel more alert during the day.

Longer life

More studies of humans are needed to determine whether fasting adds years to your life, say scientists. But so far, studies have shown that it can improve health in some ways, such as reducing cell damage, which can help you live longer.

A stronger immune system

Fasting can help boost immunity, but little research has been done on humans. Clinical trials in rats and a small group of people have shown that fasting during chemotherapy helps protect white blood cells and can grow new ones.

Clearer skin

There are many claims that fasting helps clear acne and improve skin, but there is little scientific evidence to support it. There is not much research to know about the effects of fasting on skin health.

Better stroke outcomes

In animals, studies have shown that fasting protects the brain from damage after a stroke and speeds recovery. But there is no evidence of this in humans.
