New research has canceled all previous findings about the popular type of diet.


The popularity of the intermittent fasting method has increased in Russia over the past year. It is used to lose weight, improve metabolism, and regulate blood sugar levels. But is this method so good? Scientists from the United States have conducted their own study that suggests otherwise.

Svetlana Bronnikova, a clinical psychologist, candidate of sciences and author of a book on intuitive nutrition, helped the Championship to translate the conclusion and understand the scientific data.

According to the results of the TREAT clinical study, obese people do not lose weight during intermittent fasting, their metabolism does not improve, and the level of inflammation does not decrease. This method of eating leads to muscle loss.

Svetlana: These data confirm that human metabolism is a much more complex structure, and the introduction of innovative forms of nutrition should be treated with great caution.

What is the essence of research?

The results of this experiment were published on September 28, 2020 on the website of the medical journal JAMNetwork. This is the first human study in the history of science on the effects of intermittent fasting on weight loss. Ethan Weiss, a cardiologist at the University of California at San Francisco, studied the effect of intermittent fasting on 116 volunteers who were stable overweight and diagnosed as obese. The average weight of the study participants was 100 kg. Some of the subjects practiced intermittent fasting and ate food from 12 noon to 8 pm. The control group ate as usual three times a day without time limits.

What are the results?

After 12 weeks, it was found that slight weight loss occurred in both groups. Scientists do not associate this effect with the type of food: weight decreases when a person begins to pay attention to what and how he eats, and in the case of participation in the study, this is inevitable. The intermittent fasting group showed no weight loss benefits over the control group. The study also did not reveal differences in metabolic parameters - in both groups there were no changes in insulin, glucose, activity level or sleep quality, and there was no decrease in the level of inflammatory processes in the body. Moreover, the group of subjects who practiced intermittent fasting showed significant loss of muscle mass (65% relative to total weight loss). In other forms of weight loss, this figure is usually no more than 20-30% of total weight loss. And this is statistically related to subsequent weight gain.

And what did the scientists say before?

Intermittent fasting has been popularized over the past seven to eight years as a method of weight loss and control, rejuvenation, health improvement, metabolic improvement (in particular, control and reduction of insulin levels in type 2 diabetes), as well as improving well-being and activity level.

Research into the effects of time-limited eating in mice began after a group of researchers led by Nobel laureate Yoshinoro Obuki of the University of Tokyo described the phenomenon of autophagy in yeast cells. A team of biologists at the Salk Institute for Biological Research in San Diego found that time-limited eating leads to weight loss in obese mice and improved metabolic health, even when fed foods high in sugars and fats.As a result, ideas about the health benefits of intermittent fasting for humans have spread widely in popular culture.

Could Intermittent Fasting Be Hazardous To Your Health?

Subsequently, research has shown that the effects of intermittent fasting found in mice cannot yet be extended to humans. Experiment leader Dr. Ethan Weiss, who had followed intermittent fasting for seven years, stopped doing it the day he first saw the results of his work. In an interview with ABS-SBN News, he said that he was shocked by the findings, and that he considered it premature to prescribe such a diet to his patients. In addition, Weiss stressed the need for further research, especially regarding the safety of intermittent fasting for the elderly (60+) and people with chronic health conditions such as type 2 diabetes.

Svetlana: I know, for example, that endocrinologists in Russia widely prescribe three or even two meals a day for patients with type 2 diabetes, claiming that this stabilizes insulin. Unfortunately, these are potentially hazardous practices with unpredictable effects. A complete and balanced diet, the number of meals that meets the needs of a person and his level of activity, the absence of rigid rules and restrictions, and nutrition in accordance with the signals of hunger and satiety, that is, relying on the principles of intuitive nutrition is still the most effective and scientifically proven method to stay healthy and not gain weight in the long run.
