Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Child Weight/NutritionMy son is 4 years old and one month. He's 39.36 inches tall and weighs 40 pounds even. According to bmi he is obese. I am asking what would be good numbers of calories and nutrients to feed him? He's very active so I'm not concerned about excercise. Also his pediatrician says his weights fine and that bmi's don't always work right for children, is that accurate? Should I just not worry because a growth spurts close? I'm prone to worrying when there's no problem so maybe the doctors right? The only reason I'm even doubting the doctor is because he is, at a guess 375-400 pounds, and I worry he is more okay with obesity than he should be. My son was 9 ppunds and 8.9 ounces at birth, caucasian, non-Hispanic. If that's relevantEdited to add: He has just gotten over pneumonia twice and has low IGG, we are seeing an immunologist soon to figure out why. So taking him places to figure out calories and nutrients isn't really possible right now because we are staying inside. Just hoping for advice until I can take him out, thank you :). ### Response: Obesity at his age is highly associated with adult obesity, but far easier to fix now than later. Some kids slim down but many do not.Easiest solution is to meet with a registered dietician (NOT a nutritionist). They can help you plan meals so he has the right number of calories / balance of nutrients.That being said, the easiest (and one of the more effective) ways to slow weight gain is elimination of all liquid calories, even milk. Only water to drink..
