And now a new study by American scientists showed that this extreme diet increases the likelihood that a person will have a large amount of fat in the abdomen, but muscle mass, on the contrary, will decrease.
Their findings the researchers made experiments involving laboratory rats, which restricted the number of calories received daily. In the end, this not only led to an increase in waist size in rodents, but also to the reduction in muscle mass. Moreover, intended for the growth of the blood pressure hormone angiotensin II became hyperactive in the body of these animals, which are adhered to crash diets.
