We’ve all been there. After inhaling a delicious salad at lunch or enjoying a wholesome dinner with friends, you sense a hunger that continues to linger and just won’t leave. The faint grumbling noises coming from your tummy suggest you’ve not fed your body sufficiently. As a result, you go for a few extra helpings, or overcompensate with dessert.

The truth is, oftentimes the ravenous sensation you experience after eating doesn’t mean you need more food. Instead, you’re probably exercising some small yet powerful behaviors that invite rebound hunger, which can ultimately add inches to your waistline. For example, certain foods might carry a boatload of calories, but their high glycemic index trigger surges in your insulin levels, which prevents you from feeling the effects of leptin, or the fullness hormone.
