In another effort to help women achieve society’s current conception of slender beauty, or at least achieve a healthy weight, scientists have determined that exercise does not reduce the appetite of obese women as it does for their slender counterparts. Three separate studies confirmed these findings. During periods of exertion, the body secretes larger amounts of a hormone called leptin, which is responsible for feelings of satiety. While obese individuals do produce leptin on par with slender individuals, they seem to develop a resistance or decreased sensitivity to the hormone. So, this vicious reality means that the seriously athletic might want to eat even if their not feeling hungry and the seriously overweight should refrain from eating every time they get hungry. In conclusion, don’t listen to your gut if it has a history of bad advice.
