I want you to take a look at this photo. There are 5 lbs of fat and 5 lbs of muscle. As you can see 5 lbs is 5 lbs. Muscle does not weigh more than fat. A woman weighing 120 lbs with 19% body fat is healthy and looks much better than a woman weighing 120 lbs with 28% of body fat, though they weigh the same. Please do yourself a favor and don't be obsessed with body weight. Start paying attention to body composition muscle to fat. That perspective will be most helpful to you in the long run. To peace of mind and great health, Jerome Downey
