Macronutrient amounts are often described in two ways: as a percentage of total daily calories and as grams per kilogram of body weight. The combination of 10-35% of daily calories with 0.8 g per kilogram matches the standard protein guidelines: protein typically contributes about 10-35% of calories and is about 0.8 g/kg for many people. This dual format is specific to protein. Carbohydrate guidance for athletes usually appears as a higher percentage of calories (roughly 45-65%) or as a larger range in g/kg (commonly around 3-7 g/kg, depending on training). Fat recommendations sit in about 20-35% of calories. So, while the question mentions carbohydrates, the option that correctly describes a nutrient using both the percentage-of-calories and g/kg format aligns with protein guidelines, which is why it’s chosen as the best answer.
