In this study, we set out to perform a comparative evaluation of variations in body weight and volume between two groups of women, one young adult and the other perimenopausal, each of which followed a specific weight loss program for the same period of time. The evaluation was based on the weight and volume data obtained from a clinical and anthropometric study. From the anthropometric values obtained, we conclude that in both groups of women, the diet followed was found to be effective in reducing weight and volume, but with respect to time, the weight loss was more noticeable among the younger women, while among the menopausal women it took place more slowly. The difference between the two groups might be explained by diverse hormonal effects, such that metabolism (and therefore caloric expenditure) is higher among the younger women.
