When you're trying to control your calorie intake, it's important to be mindful of what and how much you're drinking. Although milk and juice have important nutrients and can be part of a healthy diet, they still have calories — and calories in liquids can add up even faster than can calories in food.
So when you're counting calories, your best beverage choice is water. Keep higher calorie beverages in check. As a general rule, drink no more than 4 ounces (118 milliliters) of juice a day and 16 to 24 ounces (473 to 710 milliliters) of skim milk a day. Also be careful about energy drinks. Although they're touted as healthy, energy drinks can have as much added sugar as sodas — the top source of added sugar in the American diet.
If you get hungry between meals, snack on fresh fruits and vegetables. Whole fruits and vegetables are much more filling than juice — and it's likely you'll consume fewer calories with these choices.
