The rebound effect of the diets.
A group of Spanish researchers has found that the rebound effect of the diets (recovery of lost weight) weight loss is due to the presence of two hormones leptin and ghrelin. In the published study, scientists have observed that this result occurs when there is high leptin and low ghrelin.
Leptin and ghrelin are to blame. The answer to those who, after dieting, recovered kilos or fat, can be in two hormones, leptin and ghrelin. In one study, the levels of these molecules determine the success of attempts to lose weight.
The researchers analyzed plasma levels of hormones such as ghrelin, leptin and insulin together in 104 overweight people who had been subjected to a hypocaloric diet. After eight weeks, the group recovered more than 10% of lost weight had higher leptin levels and lower levels of ghrelin. No differences in insulin levels.
Furthermore, the results published in the Journal of Clinical Endocrinology & Metabolism, also show a specific influence of ghrelin between men and leptin in women. “The response to treatment is predetermined by specific characteristics of each patient,” the study’s lead author and doctor at the Hospital Universitario de Santiago (CHUS), Bethlehem Crujeiras.
People who are obese or overweight who gain weight after dieting may be identified even before starting the diet for weight loss only to analyze the plasma levels of these hormones, “said the specialist, who advised that” endocrinologists and nutritionists should design a special program for patients with higher plasma levels of leptin and lower ghrelin before starting a low calorie diet. ”
