Losing weight can be hard. But keeping if off is usually just as big of a challenge as losing it is. And now we have a better understanding as to why it's so hard to keep the weight off. It all comes down to our hormones that control our appetite. Hormones that may be altered for up to a year after we lose weight. Yes, a year.
New research in the New England Journal of Medicine looked at 50 overweight or obese people as they went on a low-calorie diet for 10 weeks. Researchers then measured levels of several key hormones — the "hunger hormone" ghrelin and the "I'm full hormone" leptin — before they started the diet, after they completed the diet and then again 62 weeks later, according to WebMD.
