In brief: More calories/gram
Fats contain 9 calories in every gram while carbs and protein have only 4 calories per gram. So eating a food that is mostly fat will give you more than 2 1/2 times the calories of a food the same size that is mostly carbs or protein.
For example, putting a tablespoon of butter or margarine on a slice of bread will give you 2 1/2 times the calories as a tablespoon of jam, which is mostly carbs.

Oops, I meant to say that fats have more than 2 times the calories of carbs and protein.

In brief: Fats are double
Fats have double the calories per weight compared to carbs or proteins.
A small handful of nuts or cheese can carry 300 calories. Hence, it is best to avoid. Also, the saturated fats are harmful in several ways.

In brief: Caloric density
Fats are high in calories, 9 calories per gram versus 4 for proteins and carbohydrates.
So limiting fats in the diet help reduce total daily calories and helps one lose weight.
