For instance, although juice and milk have important nutrients, they contain a lot of calories. Drink reduced-calorie juice or dilute juice with plain or sparkling water to help lower the calorie count. To help cut calories in milk yet still get your calcium, switch to fat-free milk. Water is still the best choice when it comes to satisfying thirst, though. And if you're hungry, snack on fresh fruit, not fruit juice.   Need practical advice on diet and exercise?
