Whatare the foods that have high calories?

Oils and fats: Oils and fats have higher calories. Proteins and carbs (starches, sugars) have lower calories than oils and fats have. More importantly is the amount of food one eats. For example, eating 12 ounces of protein has more calories than eating 3 ounces of fats. One must also consider the nutritional value of the foods (but that's another story).
