Abstract: Disclosed are combinations of soy protein, chromium and free leucine in amounts effective to inhibit the loss of lean body mass of a subject under conditions of caloric restriction. The soy protein, chromium and free leucine can be administered in several products, including a powder that is mixable into a liquid beverage (such as a shake), a snack bar, and a nutritional supplement (such as one or more tablets). Some embodiments also include corosolic acid and/or a tea drink that provides an effective dose of taurine. The products may be contained in kits containing the disclosed combinations as well as methods of using the products for weight loss and the inhibition of the loss of lean body mass in a subject during weight loss. The products and methods are also useful in the improvement of lipid profiles (for example reducing total cholesterol and LDL cholesterol levels).
