The human body is composed of two broad compartments: (i) active tissue mass (lean body mass or fatfree mass) and (ii) the fat mass which is the principal store of energy in the body. In steady state, an individual will maintain his body weight when the input of food energy is equal to the output of energy. Under these conditions, any change in body weight indicates a change in energy balance a...

The relation between relative weight and health differs between young and old. In older populations, weight change may cloud the association between a single relative weight and health outcomes. To determine whether weight or weight change is a more important determinant of mortality in a population of older adults, the authors analyzed data from the Systolic Hypertension in the Elderly Program...

Leptin is an adipocyte-derived hormone involved in regulation of satiety, and it also appears to have a role in breast cancer risk. Leptin therefore might be a useful indicator of the potential preventive effects of weight loss in breast cancer survivors. In this study we examined whether the change in leptin levels could be predicted by weight loss in obese breast cancer survivors. The subject...

BACKGROUND The aim of this study was to determine if oral contraceptive (OC) use affects body weight, body composition and metabolism in primates. METHODS Reproductive-age female rhesus monkeys of normal and obese BMI were studied to document baseline weight stability, then treated continuously with an OC (dosed to achieve equivalent human serum levels for a 30 µg ethinyl estradiol/150 µg lev...
