Studies show that as we age normal weight gain is one to two pounds a year. Along with this gain is a loss of muscle mass and a gain in fat tissue which is metabolically less active. An ideal weight loss program should include a weight training regimen. For every pound of weight we lose a majority of it is lost in muscle. The benefit of working with weights is to enable a person to hold on to much of the muscle which otherwise would be lost. A study was conducted at Forest University of Winston-Salem, N.C.. There were 249 participants all from different ethnic backgrounds. All of the participants diets were reduced by 300 calories a day. Group 1 dieted but did not exercise. Group 2 added a walking routine and group 3 added weight training. At the end of 18 months the group who trained with weights retained more muscle mass and an increase in overall strength. The researchers concluded that weight training might be the best way to supplement walking while reducing calorie intake.
