Now more and more people are trying the new dietary method of intermittent fasting. As a dietary method, intermittent fasting has rapidly become popular worldwide in recent years, attracting a large number of people to try it. This dietary pattern is not only considered an effective weight loss method, but also believed to bring benefits to physical and mental health. What is intermittent fasting? Intermittent fasting is a dietary pattern that cycles between fasting and a normal diet. It doesn't specify which foods you should eat, but when you should eat them. Intermittent fasting does not involve tracking calories. This dietary approach is mainly achieved by limiting the daily eating time, rather than by accurately calculating the amount of calories or protein, fat, and carbohydrates consumed. HealthKit： We import your exercise data from Apple Health to help you understand your daily exercise routine. The intermittent fasting app will provide you with: Fasting Tracking: Intermittent fasting is tracked according to your fasting plan, and you can check your fasting progress at any time to see which stage of intermittent fasting your body is currently in. Weight Tracking: Record the trend of weight changes through daily weight check ins. Drinking water tracking: Set daily drinking water goals and track completion status.
