For the general population, carbohydrate intake is typically 45-65% of total daily calories or about how many grams per kilogram body weight?

• A. 45-65% total daily calories, or 3 g/kg body weight
• B. 4-5 g/kg body weight
• C. 8-12 g/kg body weight
• D. 10-35% total daily calories, 0.8 g/kg

Answer: (A)

Carbohydrate intake for most adults is described both as a percentage of daily calories and as grams per kilogram of body weight. Carbs provide about 4 kcal per gram, so 45-65% of a typical daily intake (around 2000 kcal) translates to roughly 900-1300 kcal from carbohydrates, which is about 225-325 g of carbs per day. When you divide that by body weight, it comes out to roughly 3-5 g of carbohydrate per kilogram of body weight for many adults. Saying about 3 g/kg is a practical, widely used shortcut for the general population, reflecting that range. The other options either point to protein amounts or to higher carbohydrate needs seen in athletes, not the general population.
