Hormonal responses of women insert in a 12 week weight loss program based on regular physical training and a low carbohydrate diet

Aim. The present study aimed to analyze the effect of a 12-week low-carbohydrate diet and regular intermittent training on weight loss and hormone levels. Results. Participants of both groups exhibited weight loss and improvements in body composition with training and hypocaloric diets, regardless of the diet’s CHO content. However, reduced levels of the hormones T4, free T4, and testosterone were found in the L-CHO but not the A-CHO group. Conclusion. Weight loss through hypocaloric diets in combination with training resulted in hormonal changes favorable to insulin and catabolic control. The low-carbohydrate diet, in contrast, resulted in undesirable changes in the homeostasis of thyroid and anabolic hormones.
