Calorie restriction promotes weight loss regardless of the glycemic load of the diet, according to the results of a phase I study, coordinated by Susan Roberts, Research Center for Human Nutrition at Tufts University in Boston (United States ).
"Study participants showed a progressive weight loss after one year of monitoring whether the foods have a low or high glycemic load," explained Roberts.
In reaching these conclusions the scientists evaluated 34 overweight people to whom were assigned randomly to a diet with variations in glycemic load.
After six months of follow-up, researchers found that the group that received a diet with low glycemic load decreased by 10.4 per cent body weight, 1.4 percent more than the rest of the participants who received a diet with a higher glycemic load.
Glycemic load
According to Roberts, the study results suggest that the effect of a good diet depends on calorie restriction and not glycemic load of foods. "In the two groups evaluated the same reduced amount of calories by 30 percent, and both showed a significant weight loss-an average of 8 per cent of original body weight, regardless of the glycemic load of the diet prescribed" .
During the study, scientists also noted the factors that influenced the degree of anxiety and satiety of the participants.
Unlike other published studies showing that a diet with low glycemic load promotes weight loss in the short term, the data obtained in this investigation did not reveal differences in the short to medium term, said the coordinator of the trial. "However, we found that the effect of diet with low glycemic load less favored the reduction of weight, so the study suggests that to maintain a diet with low glycemic load is necessary to apply a higher calorie restriction."
In weight reduction is the key not only in the number of calories you eat, as some suspect. The study's authors want to make clear that miracles do not exist.
In addition to consuming a balanced diet, you need regular exercise to reduce overweight by metabolic control, it is also in additional benefits to longevity.
