Intermittent Fasting Has Benefits Beyond Weight Loss

Can you fast for just a handful of days each month and drop pounds? Will cutting calories on those days help you live longer and fight disease?

How do you do it?

Intermittent fasting comes in many varieties. But a couple are the most common and best studied.

For example, the study above used an approach similar to a common five-day-per-month fasting diet. Each five-day period breaks down like this:

Day one: Eat 1090 calories. Make it a mix of about 56 percent fats (the good kind), 34 percent carbohydrates (steer clear of refined foods) and 10 percent protein.

Days two through five: Eat 725 calories, with 44 percent fats, 47 percent carbohydrates and 9 percent protein.

You may have heard of the popular “5, 2” plan, too. It involves reducing calorie intake for two days each week.

On fasting days, you eat two meals, the first around 200 calories and the second around 300 (equaling 500 for the entire day). On nonfasting days, you still follow a healthy diet (don’t switch to junk food), but you don’t have to restrict calories. You might think people pig out on those days, but over time, they truly do adjust to eating reasonably.

Even on fasting days, you get to eat real food: eggs, tomato-based soups, hummus and whole-wheat crackers, good fats like avocado. The key is how you mix them.

     What does the research say?

The recent Cell Metabolism study is one more bit of data suggesting the benefits of intermittent fasting go beyond weight loss. But weight loss is certainly a major benefit, too.

Previous research indicates fasting can have a beneficial effect on patients with diabetes and cardiovascular disease, help reduce cholesterol levels in certain conditions, affect the process of inflammation and even trigger stem cell regeneration.

There’s a lot of work being done in this field — but also a great deal left to be done to fully understand how and why fasting affects us.

     Is intermittent fasting right for you?

Cutting way back on calories — even for short periods — can be a big change. Before you try it, speak with your doctor. You need to make sure you eat the right foods, especially on fasting days, for good health.

You also need to be sure no health concerns prevent you from fasting. People with a history of eating disorders, people who are pregnant or breastfeeding, children, and people recovering from surgery wouldn’t want to try intermittent fasting.
