There is series of numbers named the 4-9-4 'rule' which relates to the amount of calories in certain types of foods that we eat. The breakdown is:
4 calories per gram for carbohydrates
9 calories per gram for fats
4 calories per gram for proteins
Carbohydrates: There are two types of carbohydrates, 'simple' which are fruits (fructose), table sugar (sucrose), honey, milk (galactose) and 'complex' carbohydrates which are typically grains like wheat flour, bran, rice, pasta, potatoes.
Fats: This category includes all oils, canola, vegetable, olive, peanut, safflower, etc... Butter, margarine, all animal fats (Beef, pork, chicken, fish, lamb).
Protein: All meat products, beans, dairy, wheat germ.
So you can see that there are twice the amount of calories per gram of fat compared to protein and carbohydrates. This is the primary reason why people tend to be overweight, it's basically because 'we' like to eat foods that are rich as the fat molecule brings a richness to foods in the mouth. Foods like a hamburger, cheese, ice cream, chocolate, french fries are all high in fats and are foods that many people like to eat. Foods with a higher fat content have much more calories than a balanced meal like a turkey sandwich and fruit.
