Volumetrics
Here is an optional step that can help with weight control. It was pioneered by Barbara Rolls, a researcher at Penn State University. The idea is to eat foods that have fewer calories than grams per serving. Take a look at the label from a package of carrots below. There are 45 calories per 85 grams of food. Since 45 is a smaller number than 85, this means the food is a high-volume, low-calorie food.
Try adding lots of soups, salads, and foods cooked in water (like oatmeal) to your daily diet. These “heavy” foods will make you fill up without taking in a lot of calories.
