My hubby is suffering from obiesity, and has lost 76 lbs. since Nov. just by counting calories and protiens; and watching sugar intake. I have learned alot about how fattening and non nutritional alot of foods are since helping him. As our metabolism slows down, we are supposed to lower our total calorie intake per day and try to make sure we get a little exercise every day. Not always easy, and I myself have recently been told I need to lose between 15 - 20 lbs. by my doc. Good luck and hope this information helps. Bought him the Biggest Loser calorie guide and it is very helpful for him or anyone.
