Weight loss: Feel full on fewer calories

Simply put, energy density is the number of calories (energy) in a specific amount of food. High energy density means that there are a lot of calories in a small amount of food. Low energy density means there are few calories in a large amount of food. When you''re striving for weight loss, one strategy is to eat low-energy-dense foods.
