Which weight loss program is good for senior men?

Moderate protein. The most important thing for seniors is to maintain muscle mass with any weight loss program, should have a goal of at least .4 grams protein per pound of body weight per day as a minimum. I suggest a program with about 20% of daily calories coming from protein, this saves muscle and bone.
Control-IT program. Biotics research has a researched program called control-it they found men lost 10-12 pounds per month and it is a medically supervised program. It is safer and focus on adding adaptogen, adrenal reset, detoxification anti-inflammatory products.
