Should You Graze?

Runners take in – and burn – a lot more calories than their sedentary kin. And most of those calories come from carbohydrates. But here's the rub: Your body can only use so many carbs at any given time… and the excess is converted to fat.

For this reason – and to keep their blood sugar levels more stable – some runners and other athletes “graze.” That is, they eat smaller, more frequent meals and snacks.

Nutritionists who advocate grazing usually suggest five or six small meals spaced throughout the day. But remember to keep your portions smaller when you're eating more frequent meals!
