Fats & Carbohydrates Provide the Most Energy

Fats and carbohydrates are the two elements that provide the most energy for all humans

Fats & Carbohydrates

Amongst the two elements, fats actually provide more energy than carbohydrates as fats provide approximately 9 kilocalories per gram, while carbohydrates provide approximately 4 kilocalories per gram. Typically providing for more than half of a body's energy needs, fats break down from food in to fatty acids which are stored in fat cells for later use. On the other hand, while fat cells have unlimited capacities, energy from carbohydrates cannot be stored in the same way and are used eagerly by our bodies after they are converted into glucose.
