Question: how much carbs should a 12 year old eat per day?
Answer: How many carbs do you need? Depending on your age, sex, activity level, and overall health, your carbohydrate requirements will vary. According to the Mayo Clinic, 45 to 65 percent of your daily calories should come from carbohydrates. That's equal to about 225 to 325 grams of carbs if you eat 2,000 calories a day.
