What is intermittent fasting?

Though many diets concentrate on what you should eat, intermittent fasting is all about when you should eat. When you practice intermittent fasting, you only eat during the allotted hours. Your body can burn fat if you fast each day for a period or consume only one meal a couple of days a week.

According to scientific findings, there are some health benefits to intermittent fasting.

The following are some well-liked methods for intermittent fasting:

  • Fasting every other day: One day, consume a regular diet, and the following day, either fully fast or consume one modest meal (less than 500 calories).
  • 5:2 fasting: Five days a week, have a typical diet, and fast two days a week.
  • Daily fasting with time restrictions: Eat normally but restrict your daily eating window to eight hours. For example, skip breakfast yet eat lunch at noon and dinner at 8 o'clock.

According to various research, alternate-day fasting is comparable to a standard low-calorie diet in terms of its ability to help people lose weight.

What are the benefits of intermittent fasting?

According to studies, intermittent fasting does more than only burn fat.

Longevity, a slimmer body, and improved intellect are a few of these.

  • According to some studies, intermittent fasting may be superior to other diets to lower inflammation and treat illnesses that are related to inflammation, such as:
  • Memory and thinking: Intermittent fasting improves verbal memory in human adults and working memory in animals.
  • Heart wellness: Blood pressure, resting heart rates, and other heart-related parameters were improved by intermittent fasting.
  • Physical ability: 16-hour fasting in young men resulted in fat loss while maintaining muscle mass. Running endurance was higher in mice that were fed on alternating days.
