Bodybuilders are people trying to perfect a good physique. Normal Americans are, generally, a little fat. > It is common knowledge among bodybuilders that an increase in muscle and loss of fat at the same time is possible only with steroids. For bodybuilders. If you're a 166-pound 5'1" 45-year-old woman who can't manage a 45-lb deadlift because of a combination of inflexibility and weakness, an increase in muscle mass and loss of fat at the same time is totally possible :) > Here we read that the people in the experiment did not limit their calories, but "lost weight". This couldn't have been fat. Why in the world not? You sound like you think all people are bodybuilders, paying attention to their nutrition, hitting the gym regularly, deciding between chicken breasts and oatmeal for breakfast, focusing on fat loss instead of weight loss. Wrong audience.
