It took me a long time to figure out why I looked so haggard after I lost weight. For years I followed whatever current fad diet claimed to melt away the pounds. I even tried vigorous walking each night. Since I am a disciplined person, all of them helped to some degree. However, even when I got aerobic exercise by walking, my arms and belly would become flabby. Finally I discovered that the secret is to burn the fat feed the muscle. As soon as I adopted an eating plan that focused on burning fat only, I reached my target weight and look.
