Diet Drinks Fool Body's Metabolism By Chauncey Crandall, M.D. When people go on a diet, they often drink artificially sweetened drinks and eat low-calorie dishes to help them meet a goal. Unfortunately, they may be tricking their metabolism into piling on even more weight and triggering diabetes, says a recent study from Yale University. Special: Discover This Superfoods Bible – Boost Your Health! The sweetness in naturally sweetened foods tells the body the food contains energy; the sweeter the food, the more energy it usually contains. But when a beverage is either too sweet or not sweet enough for the number of calories it contains, the body's normal metabolic response is disrupted. The study shows that sweetness helps to determine how calories are metabolized and signaled to the brain. When sweetness and calories are matched, the calories are properly metabolized, and this is registered by brain reward circuits. However, when a "mismatch" occurs, the calories fail to trigger the body's metabolism, and the reward circuits in the brain fail to recognize that calories have been consumed. As a result, the person could be compelled to overeat. |
