"Dr Michael Colgan conducted a study at Colgan Institure in San Diego California with four men and two women aged 23-40 whose weight and body fat were stable, that is, did not vary week to week by more than 2%. For six weeks, they reduced their usual lunch by 250-400 calories every day, and kept all other meals strictly at their usual levels. According to the American diet industry, that's a sure fire prescription for losing weight. Over the six weeks, subjects reduced their so-called "caloric intake" by a total of 8400 to 18900 calories. According to the calories in - calories out myth that dominates the dieting industry, these subjects should have lost substantial weight. At approximately 3600 calories per pound, they should have lost between 2,25-5,25 pounds. In fact, only one man and one woman lost any weight, the man 0,9kg and the woman 0,3kg. The other four lost nothing at all. Counting calories just doesn't add up."
