How many calories are in 1 g of fat?

The correct response reflects that 1 gram of fat provides approximately 9 kilocalories (kcal). This energy value is significant in nutrition because fat is the most calorie-dense macronutrient, compared to carbohydrates and proteins, which provide about 4 kcal per gram. Understanding the caloric content of different macronutrients is crucial for athletes and active individuals who need to manage their energy intake for performance, body composition, or overall health.

Knowing that fat provides 9 kcal per gram helps individuals calculate their dietary fat intake accurately, particularly for those who are focusing on macronutrient ratios for specific goals such as muscle gain or fat loss. This information also underscores the importance of incorporating fats judiciously within the diet to maintain balanced energy levels while still meeting other nutritional needs.
