Detailed explanation-1: -Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates.
Detailed explanation-2: -The amount of energy stored as lipids is greater than the amount stored as glycogen since the human body cannot store as much glycogen as lipids can.
Detailed explanation-3: -Because one triglyceride molecule yields three fatty acid molecules with as much as 16 or more carbons in each one, fat molecules yield more energy than carbohydrates and are an important source of energy for the human body.
Detailed explanation-4: -Fats provide 9 calories per gram, so they contain more energy than carbohydrates. They are important for brain development, blood clotting and controlling inflammation. While all types of fat contain the same amount of energy, some are healthier than others.
Detailed explanation-5: -The main type of fat we consume, triglycerides are especially suited for energy storage because they pack more than twice as much energy as carbohydrates or proteins.
