This makes sense, How many times have you seen someone lose weight only to gain even more weight back after the diet. Diet, exercise and rest definately go together, but really you need to figure out how many calories your burning compared to how many your eating. Try to lose ony about two pounds a week to keep the majority of loss as fat and not muscle. Here are some Calculators to measure your BMI, BMR,Calories Burned, and LBM calculator at http://howtogainweight123.com/calculators So, Calculate how many calories you have burned during the day and adjust your food intake to be less calories to lose weight or more calories to gain weight. Sounds simple, but actually doing it is the hard part :]
