Mattson explains, “When changes occur with this metabolic switch, it affects the body and brain.” Research shows that the intermittent fasting periods do more than burn fat. But, he observes, research subjects who make it through the adjustment period tend to stick with the plan because they notice they feel better. You might feel hungry or cranky while you’re getting used to the new routine. Mattson’s research shows that it can take two to four weeks before the body becomes accustomed to intermittent fasting. Going too long without eating might actually encourage your body to start storing more fat in response to starvation. Longer periods without food, such as 24-, 36-, 48- and 72-hour fasting periods, are not necessarily better for you, and may be dangerous. ![]() An example would be if you chose to eat normally on every day of the week except Mondays and Thursdays, which would be your one-meal days. For the other two days, you limit yourself to one 500–600 calorie meal. ![]() That study’s results showed that reducing the number of large meals or eating more small meals may be associated with minimizing weight gain or even with weight loss over time.Īnother intermittent fasting plan, known as the 5:2 approach, involves eating regularly five days a week. For instance, you may choose to try 16/8 fasting: eating for eight hours and fasting for 16.Īlthough some people find it easy to stick with this pattern over the long term, one research study that was not designed specifically to look at an intermittent fasting pattern found that limiting your daily time window of eating does not prevent weight gain over time or yield significant weight loss results. You can pick a daily approach, which restricts daily eating to one six- to eight-hour period each day. ![]() Once you get his or her go-ahead, the actual practice is simple. It’s important to check with your doctor before starting intermittent fasting.

He refers to this as metabolic switching. Mattson says that after hours without food, the body exhausts its sugar There are many different intermittent fasting schedules. Or you might choose to eat only one meal a day two days a You might try eating only during an eight-hour period each day and fast for There are several different ways to do intermittent fasting, but they areĪll based on choosing regular time periods to eat and fast. That intermittent fasting may help reverse these trends. That can mean sitting and snacking allĮxtra calories and less activity can mean a higher risk of obesity, type 2ĭiabetes, heart disease and other illnesses.
