According to the Nutrition Facts label on many food products, Fats can supply 9 calories of energy per gram, carbohydrates and proteins have 4 calories per gram. It would therefore make sense to say humans get most of their energy from fats they eat.
However, in the United States, most peoples diet is largely of carbohydrates: breads, cakes, donuts, pasta, etc. Many foods have added sweeteners such as sugar and corn syrup. So the reality is that most peoples diets and energy comes from carbohydrates and what isn't used as energy is converted to and stored in the body as fat.
In food, there are three macronutrients that provide energy. They are fat, carbohydrates, and protein. Fat is the nutrient that provides the greatest amount of energy at nine calories per gram. Protein and carbohydrates provide only four calories per gram.
