Fat Burners Box weight loss goal: To keep weight off permanently, we believe the best goal is to reduce fat weight, not absolute body weight. In other words, you should aim to decrease body fat while maintaining lean body mass. This means you may not see as dramatic a weight loss in the first few weeks as fat is burned off and muscle is toned up. Don't be discouraged! Don't be fooled by the scale! A better measure of how you look and feel will be the mirror, your clothes, and your friends. Why? Muscle weighs more than fat, yet takes up less space. So even though you may go down 2 or 3 sizes and look great, your weight may fall only gradually.
