It’s not rocket science that over eating leads to weight gain. Still, chronic over eating can not only lead to weight gain but to metabolic issues as well. It’s like this: when you persist in eating when you’re not hungry, your biological system goes haywire trying to deal with extra calories. Leptin, the “leave it alone” hormone that makes makes you feel full, is the good guy that helps to burn fat when you aren’t hungry. Continuing to ignore leptin’s satiation cues eventually leads to leptin resistance, which means all that fat burning stops. Where does the extra fat go? Well funny you should ask! Say hello to the new, bigger fat cells made just for fat storage. Not to mention the fat buildup in organs like your liver. Pants feeling tight yet? Leptin is your friend in weight management. Listen to your friend.
