According to multiple experts,
In one study , 15% of body weight was compared in 200 people between a 'rapid weight loss group in 12 weeks' and a 'gradual weight loss group in 36 weeks'.
The rapid weight loss group ate three times a day, mainly shakes, nutritional supplements, and soups. On the other hand, the gradual weight loss group was only instructed to eat 500 fewer calories than the recommended daily intake , and was allowed to eat and drink shakes and nutritional supplements once or twice a day.
About 81% of the rapid weight loss group and about 50% of the gradual weight loss group lost more than 12.5% of their body weight. In addition, subjects who successfully lost 12.5% or more of their weight were provided with a diet that maintained their weight for approximately 2.75 years.
approximately double the loss of bone density , and has been reported to increase the risk of osteoporosis .
Three years after the first experiment was conducted, when we checked the change in body weight, it became clear that approximately 76% of the groups that underwent rapid weight loss and gradual weight loss had returned to their pre-implementation weight. It turned out that the effect is difficult to sustain regardless of the weight loss method.

In addition, dietary restrictions have side effects that lead to the risk of vitamin deficiency, weakened immune function, fatigue, and decreased bone density, and it has been pointed out that there is a possibility of malnutrition.
Many rapid weight loss methods limit or eliminate foods that are necessary for long-term health. Carbohydrates are often prohibited in rapid diets, but carbohydrates are an essential source of nutrition for the body and are said to help prevent illness. In addition, it has been pointed out that it is difficult to maintain body weight over the long term even if supplements are taken as a means of nutritional supplementation.
Mr. Nick Fuller of the University of Sydney says that a successful diet should include 'a diet program based on scientific evidence,' 'diet under the supervision of a qualified medical professional,' 'diet and exercise, Instead of making sudden changes to your lifestyle, such as sleep, make gradual changes and try to form healthy habits that will last a lifetime.”
