A number of well-controlled scientific studies have demonstrated that a very low carbohydrate diet promotes fat loss while maintaining or even increasing muscle mass. For example, Dr. Young and co-workers compared three diets containing the same amounts of calories (1,800 kcal/day) and protein (115 grams/day) but differing in carbohydrate content. After nine weeks on the 30-g, 60-g and
104-g carbohydrate diets, weight loss was 16.2, 12.8 and
11.9 kg and fat accounted for 95, 84, and
75% of the weight loss, respectively. So, the authors concluded, "Weight loss, fat loss, and percent of weight loss as fat appeared to be inversely related to the level of carbohydrate in the isocaloric, isoprotein diets.” In layman’s terms, the more carbohydrates these test subjects consumed, the less body fat they lost. This study was published in the well-respected American Journal of Clinical in 1971, but was evidently ignored by obesity ‘authorities’ (don’t confuse me with the facts, a calorie is always a calorie).
