Low Calorie Density Foods

The first food on the list is "low calorie density foods," those which "contain a ton of weight and volume for relatively few calories," explains Ehier. "People who eat these foods consume fewer calories everyday but end up eating more actual food than those who don't eat these foods." He says that the best low calorie density foods for belly fat loss are "most fruits, vegetables, and low-fat foods."

However, he doesn't recommend completely restricting yourself from high calorie density foods. "You just want to eat less of them and add more low to moderate calorie density foods into your diet. For example, during breakfast, instead of having high sugar granola, go for a whole grain cereal with fruit," he says.

Collingwood adds that the concept is also called "volumetrics" which is eating high water, high fiber foods that are dense in nutrition but fairly low in calories. "These foods fill you up and keep you full for longer and you look at a plate FULL of food, which feels good psychologically when you are trying to lose weight and don't feel like you are eating really small amounts of food," she explains.
