How many calories are in fats, carbs, and protein?
Fats contain the most amount of energy per unit weight (grams). Fats come in at 9 calories per gram while carbs and protein both come in at 4 calories per gram.
One of the big reasons that excessively high-fat diets are extremely bad for health is because these diets often are really high in calories.
While there can be other reasons, the fats themselves are usually too unhealthy to a person, if they are the right fats, but they are high in calories so if you eat too much you will gain weight and suffer health consequences.
