Foods high in fat have the most energy per gram (i.e. 9 calories/gram vs. 4 calories/gram for carbohydrates or proteins).
This is why it is easy to get fat if you eat fatty food and are not performing work involving lots of physical labor to burn those calories.
Lipids, otherwise know as fats, supply the most energy, 9kcal to be exact.
Complex carbs provide the body with energy for a long time and simple carbs provide the body energy for a short time.
