Fasting for dinner and losing weight

The team from Southern Medical University, China conducted a study on 139 obese people with BMI between 28 and 45. The results of the study were published in The New England Journal. of Medicine (NEJM) of the United States.

The researchers divided the participants into two groups:

– Group A applies a diet with restrictions on time and energy intake: Only eating from 8 am to 4 pm, and at the same time restricting the amount of calories loaded into the body. Group A is called the no-dinner group.

– Group B only applies an energy-restricted diet: This group can eat at any time but needs to control the amount of calories ingested in a day. Group B is known as the less uniform eating group.

The results showed that the group A diet had a certain weight loss effect, but considering the whole process, the weight loss effect of group A was not high.

The researchers said that fasting at night without controlling calorie intake at other meals of the day could not achieve the weight loss effect. The key to losing weight is to take in fewer calories than you expend.

In addition, research also shows that the method of weight loss by fasting is difficult to adhere to. Even with the guidance and supervision of experts, 15% of the study participants still gave up on losing weight midway. This is also the reason why in terms of weight loss, group A has a lower weight loss effect than group B.
