Efeitos da redução de carboidratos da dieta associada a exercício físico em um programa de perda de peso

Abstract

The restriction of carbohydrates in the diet has been used as a strategy in weight loss and improvement of hormones parameters, however, how many of this nutrient reduction can occur, especially when associated with exercising, without harmful consequences to health and adherence to dietary follow-up among individuals with overweight is unclear. It analyze dietary adherence of individuals entered in the weight loss program and the effect of the adoption of diets with different carbohydrate levels on weight loss, body composition and hormonal markers of overweight individuals. This study was an experimental and randomized clinical one. The subjects were divided into two groups, one with carbohydrate restriction (R-CHO) and another with regular carbohydrate intake (A-CHO), however both groups followed the same training protocol (3x/week). All individuals were assessed at baseline and 12 weeks after baseline. Both groups showed similarities on the reduction of the evaluated anthropometric parameters, but the group with dietary carbohydrate reduction had higher scores in dietary difficulties following evening meals (p <0,05), as well as reductions over the 12-week intervention, the hormone levels of T4, free T4 and testosterone (p <0,05). This leads to the conclusion that caloric restriction and training with no reduction of carbohydrate intake are able to promote weight loss addition to hormonal changes characteristic weight loss process, this strategy can be maintained for longer and with less reports of difficulties to follow the diet.
