A new investigation conducted in the United States revealed that people who continuously make a diet , they lose weight and then they gain weight again and later they make another diet , are healthier and tend to live longer, compared to those who do not care about body weight and remain with some degree of overweight Y obesity .

The scientists of the University of Ohio, they subjected mice to continuous 4-week regimens in which they first lost weight and then increased body mass. They discovered that these animals managed to live 25% more and with better levels of glucose in the blood that another group of mice obese fed a high-fat diet.

In this regard, the doctor Edward List , who led the study in the Institute of Biotechnology, University of Ohio , he said: "If the conventional belief were true, that would discourage many people with overweight lose kilos more. Our study shows that the simple act of gaining and losing weight does not seem to be detrimental to one's life prospects. "

To check whether the so-called "yoyo diets" are actually harmful to health, Dr. List carried out several experiments with 30 laboratory mice. The animals were divided into three groups and subjected to three subsistence allowance different for 2 years.

The first group was placed in a fat diet , the second group was subjected to four weeks diet, first to a low fat diet to lose weight, then to a high fat diet to recover the lost kilos and gain weight.

The conclusion is that the mice of the first group, those who ate more and weighed more, had higher levels of body fat and blood glucose than the rest of the mice. These, they became intolerant to the glucose , and therefore, with a greater predisposition to develop diabetes .

The second group, that of the "yoyo diet", showed a deterioration during the periods of the diet rich in fats, but during the low-fat diet their glucose levels and their weight returned to normal. When animals' longevity was measured - which is considered the benchmark for measuring health status - the scientists found that mice in the "yoyo diet" lived 2 years 4 months, compared to 1 year 5 months the rats obese .

Those of the third group - who were not obese, nor did "yoyo diets" - lived 2 years 9 months. Scientists believe that at lose weight , although it is temporary and brief, it prolongs life, since the animals experienced a reduction in the levels of cytokines , proteins that regulate the function of several cells in the body, including those linked to inflammation, a disorder associated with diseases such as diabetes , heart disorders Y Cancer .
