How many calories is a 12-year-old girl supposed to have in a day?

Answer 1

• Generally, a 12 year old girl should eat about 1,800-2,200 each day. However, it depends on her height, weight, activity level, muscle mass, etc. That's why, if you want a more accurate number of calories you need to eat, you should visit your doctor.
• It also depends on whether the 12-year-old girl needs to lose weight, maintain weight, or gain weight. Here are some examples for girls age 11, 12, and teenagers, to maintain (not lose) weight:

1. approx 1700-1800 if sedentary/not active
2. approx 2000-2200 if moderately active
3. approx 2300-2600 if active
4. approx 2800-3000 if very active.
