They are also characterized by low calorie per unit volume and low calorie density, such as lean meat, vegetables, fruits, coarse grains, skim dairy products and so on.

And the calorie density is high, and it is easier to get fat if you eat it often. For example, low-fiber fruits, drinks, sugar, olive oil, coconut oil, bacon, butter, or various snacks with high sugar content.
