13 Best Intermittent Fasting Apps To Try In 2024

Intermittent fasting is an eating pattern where people cycle between periods of fasting and eating. It is not directly related to dieting — it does not change what you eat; it changes when you eat.

There are many different variations of intermittent fasting. The most popular ones are:

  • The 16:8 Method: involves fasting every day for 16 hours and restricting your daily eating window to 8 hours.
  • The 5:2 Method: involves eating normally for five days and then restricting your calorie intake to 500-600 calories on the other two days.
  • One Meal A Day (OMAD): is an extreme fasting method where you fast for 23 hours a day and eat whatever you like for one meal.

If you do choose to try one of these variations, make sure that the food you eat contains all the proper nutrients your body needs.

Several studies suggest that intermittent fasting can effectively prevent weight gain and promote weight loss. In fact, this type of short-term fasting can increase your metabolic rate by 4-14%, helping you burn even more calories. According to an in-depth review paper published in ScienceDirect, intermittent fasting can result in 3-8% weight loss over 3-24 weeks.

Overall, it can be an incredibly powerful method for weight loss. If you want some good resources to help you adapt this method, we have gathered some of the most useful, feature-rich intermittent fasting apps.
