Hoping to lose weight, but heard exercising makes you hungrier? Don’t cancel your gym membership just yet.
In a small study in Medicine & Science in Sports & Exercise, two groups of subjects reduced their daily calorie totals—one by eating fewer calories, and one by exercising to burn off the calories.
The intriguing finding: Ghrelin, the hormone that controls hunger, spiked in subjects who ate less, which made them want to eat more. But there were no ghrelin spikes in those who exercised without dieting—in fact, at a shared buffet table, they ate almost 300 calories less.
