Milk ranks high on the list of fat-burning foods. No doubt you've read about or heard the commercials for milk to help you lose weight. The high calcium content of milk helps it turn off a key obesity gene, keeping your body from turning up the fat-making machinery to high, and helping your fat-burning metabolism run smoothly. At the same time, milk is the primary source of whey protein, shown in studies to enhance fat burning and limit the turnover of calories into fat storage by the liver. Subjects on a calorie-reduced diet given 20 grams of whey protein supplement every day after an exercise bout lost significantly more fat and maintained significantly more muscle mass compared to subjects given a placebo. Milk is a natural source of whey protein, and you will benefit from adding the protein supplement to your diet.
