Fat is a major macronutrient and a primary source of energy in the human diet. Scientifically, fats (triglycerides) are broken down in the body to release fatty acids, which are then metabolized in the mitochondria to produce ATP—the energy currency of cells. This process is especially important during prolonged exercise or periods of fasting, when glycogen (carbohydrate) stores are depleted. Dietary fats provide more than double the energy per gram (about 9 kcal/g) compared to carbohydrates or proteins (both about 4 kcal/g). Numerous studies and nutritional guidelines recognize the role of dietary fat in supporting energy needs, particularly in situations requiring sustained energy release. While excess fat intake is linked to health risks, moderate intake is essential for optimal physical and cognitive performance, hormone production, and absorption of fat-soluble vitamins. There is robust scientific consensus on the energy-providing role of dietary fat, though it is not typically used as a rapid remedy for acute fatigue. Instead, its role is foundational for baseline energy metabolism. In summary, fat is scientifically validated as critical for supporting and sustaining energy, both at rest and during increased energy demands.
