Aging is generally associated with a progressive gain in fat mass and loss of muscle mass. Although weight loss by caloric restriction might be anticipated to be of benefit, traditional caloric restriction-induced weight loss typically promotes an acceleration of muscle atrophy, and further reductions in physical function despite weight loss. Consequently, geriatricians often do not recommend weight loss. Myo-Canine is a food product that maintains skeletal muscle while reducing fat in obese animals.
