Many of the water-rich foods are high in fiber but low in calories. Researchers have found that the body senses it is full by the volume of food and not by the number of calories consumed. By filling up on water-rich foods first, you end up feeling full, eat less high-calorie foods, and in the end eat fewer calories over the course of that meal.

Some of the water-rich foods are classified as negative calorie foods, meaning that it takes more calories to digest them than what is contained in the food itself. Let’s take a look at some of these foods that fill you up fast:

  • Fruits and vegetables, like spinach, broccoli, cucumber, tomato, carrots, watermelon, berries, and apples.
  • Low-fat or fat-free milk products, such as milk, Greek yogurt, cottage cheese.
  • Non cream-based soups, including soups made from vegetables, chicken or beef broth, or tomatoes.

Start With an Appetizer

To eat fewer calories during your main course, start your meal with an appetizer made from one of the above foods. A bowl of broth-based soup or a green salad (without the cheese or croutons) make great appetizers that partially fill you up so that you eat less of the high-calorie main entrée.

Food Preparation

How vegetables are prepared can either keep them healthy or add calories and fat that you don’t need. Instead of frying or cooking with creams or butter, try steaming and add in some spices for flavor. Steaming also preserves most of the nutrients that would be otherwise lost in many of the other preparation processes that use high heat.

Rethink Your Drink

You might eat a nice low-calorie meal, but if you wash it down with a high-calorie drink, all is for naught. Instead of drinking high-calorie laden sports drinks, alcohol, or fruit juices, drink plain water with lemon, sparkling water, or unsweetened ice tea. If you like to drink milk with your meal, make sure it is skim or one of the milk alternatives.

Eating fewer calories doesn’t mean eating less food; it means eating foods rich in water and fiber but low in calories. Once you get used to eating this way, you won’t want to go back to the high-calorie, high-fat heavy foods.
