Several diet programs out there teach people how to lose weight by eating more instead of eating less. These programs operate on the principle that certain foods have a lower calorie density than others but are lose weight more filling than the higher calorie choices. Fruits and vegetables, which have a higher water and fiber content than fatty foods, can help a person to eat fewer calories without even missing them. Whole grains and legumes are other foods that because of their fiber content can easily replace fattier foods in the diet without making a person feel like he or she is missing something.

Some companies have designed foods with different ingredients and fewer calories that will allow people to eat larger portions than normal brands would recommend as a serving size. For example, instead of a half cup serving like other ice creams, Arctic Zero offers an ice cream that has 150 calories per pint. This can really benefit dieters who are not satisfied with the portion sizes recommended by standard products.
