About this study
This study plans to learn more about why menopause increases the risk of weight gain. During and after menopause, women are prone to increased weight gain. The weight gained is primarily body fat, particularly visceral or abdominal body fat. The excess gain in abdominal fat during menopause increases the risk of chronic metabolic diseases such as heart disease and diabetes. The increase in weight and body fat with menopause may be due to changes in metabolism related to the loss of estrogen. This study plans to compare how the metabolism of premenopausal and postmenopausal women responds to changes in energy intake. The investigators will compare the changes in energy expenditure that occur during a period of acute fasting (24 hours) and a period of consuming excess calories (overfeeding).
