In recent years, interest in new forms of nutrition has steadily increased, including intermittent fasting. Intermittent fasting is a form of nutrition in which you alternate between eating and fasting. There are different types. This study examines Time-Restricted Eating (TRE) in the sense of the 16/8 method and Alternate Day Fasting (ADF).
With the 16/8 method, you eat as much as you like in a time window of 8 hours (12:00-20:00) and then fast for 16 hours. The ADF method alternates between eating and fasting days. You eat as much as you like for one day and then fast for a whole day. Animal studies have shown that intermittent fasting leads to weight loss and reduces the risk of chronic diseases such as type 2 diabetes mellitus and cardiovascular disease. Life-prolonging effects were also observed. To date, there have only been a few clinical studies on humans investigating the effects of intermittent fasting. However, the data to date show that intermittent fasting can have a positive effect on health and weight loss, especially the reduced loss of muscle mass, and has no negative side effects. However, there is still no study directly comparing the two types (TRE and ADF) in people with obesity, so it is not known which type has better effects on various health parameters.
