Eat more, lose more

Fill up on soups and other high energy-density foods.

Research shows that foods with high water content fill you up faster and for a longer period of times. Fruits, vegetables and broth-based soups all fit the bill.

By starting a meal off with a bowl of soup or a healthy salad, dieters reduce their overall calorie consumption for each meal.

In addition, it's possible to eat larger volumes of these foods for a smaller amount of calories.
