What nutrients yield the highest amount of energy per gram when metabolized?

Answer 1

starch is the nutrient that provides greatest amount of energy. during the process of digestion starch is converted into maltose which is then converted into glucose. breaking down of 1 glucose molecule provides 2780kilo joules of energy.

Answer 2

Fat yields the highest amount of energy per gram when metabolized, providing 9 calories per gram. This is more than double the energy provided by carbohydrates and proteins, which each provide 4 calories per gram when metabolized.

Answer 3

The nutrients which release energy in the body are glucose and fats.

Glucose is often used first, and fat is stored.

However, fats actually release more energy than glucose. 1 gram of fat releases 39 kJ of energy, whereas 1 gram of glucose releases only 17 kJ of energy.
