Caution: Snacking when you're beyond hungry

It's easy to lose control of what and how much you're eating if you snack or have a meal when you're famished. And if you leave your snack choices to chance, you end up grabbing whatever is accessible from a vending machine, coffee cart or convenience store. Chances are, what's available won't necessarily be what's healthy.

The fix: Plan snacks ahead of time. Healthy snack choices contain 100 to 200 calories and a combination of protein (for lasting fullness) and produce, which can keep you feeling full with its high water content. Good choices: 1 tablespoon of peanut butter smeared on a few stalks of celery, string cheese and a small apple, or a small container of plain low-fat yogurt with sliced strawberries.
