Fats: an efficient source of energy
The sources of energy used for physical activity in daily life and sports are primarily lipids and carbohydrates.
Lipids are an efficient source of energy (9kcal per gram) that the body stores in relative abundance. They also play an important role as building blocks for cell membranes, hormones, and physiologically active substances.
However, since the excess intake of lipids accumulates in the body as fat, it is necessary to find ways to use this excess energy.
Lipids are essential for cells to function properly.
