More evidence that milk is the ultimate fitness food.

Instead of fruit juice, reach for milk in the morning—it will help you eat less at lunch, according to Australian scientists. In their study, overweight people who downed two and a half cups of skim milk during breakfast consumed more than 8 percent fewer calories at lunch than people who drank the same amount of fruit juice. Both beverages have an equal number of calories, but only milk contains protein, which takes longer to digest than carbs, helping you feel fuller for longer.

Just be careful not to pair your milk with a sugary cereal, a carbohydrate-dense pastry, or any other high-calorie catastrophe.
