Time limited eating refers to a dietary pattern of eating according to a certain pattern and within a specified time. The optimal eating time window for a limited time diet is not yet clear. A study showed that a 16 hour (fasting)+8-hour (eating) limited time diet plan, especially fasting after 5 pm every day, not only helps with weight loss, but also reduces visceral and subcutaneous fat, and lowers blood sugar levels. This study is a three-month multicenter randomized controlled trial that included 197 obese or overweight individuals. The trial used magnetic resonance imaging to detect changes in visceral fat and subcutaneous adipose tissue, and divided them into four dietary patterns: conventional simple Mediterranean diet; Early morning limited time meals are eaten from 9:00-17:00; Late limited time meals are available from 14:00 to 22:00; Choose your own limited time diet, that is, choose your own 8-hour eating time window. It was found that regardless of the time of the eating window, there was no significant reduction in visceral fat compared to a simple Mediterranean diet. Compared with the conventional Mediterranean diet, those who do not eat after 17:00 have a more significant reduction in subcutaneous adipose tissue. In terms of weight, compared with the Mediterranean diet, the other three time limited diets were able to reduce weight by 2.9, 2.4, and 3.1 kilograms, respectively, with no difference between the three time limited diets. Further analysis revealed that compared to the other three groups, the fasting blood glucose and nighttime average blood glucose levels of the early time limited diet group decreased on average.
