How many calories does a 15 year old 96 pound boy need?

It varies a little based on weight, height, activity level, and a few other factors, but on average about 1,400 to 1,600 calories a day.

Unless you're spending quite a bit of time in vigorous of strenuous activity, you'll probably need about 2300-2500 (good quality, How_many_calories_should_a_14_year_old_boy_eat_per_daypacked) calories per day.

According to the national How_many_calories_should_a_14_year_old_boy_eat_per_dayorganisation and average 14 year old boy needs 2800 calories a day when doing lots of activity, 2500 if not very active, and around 1800-2100 calories if not doing any activity.

Calorie intake depends on a variety of answers. If the boy is very How_many_calories_should_a_14_year_old_boy_eat_per_dayhe should consume anywhere from 2500-2800, moderately active should consume 2100-2400 and if little or no activity anywhere from 1700-2000. Then again, if the boy's mass includes more lean muscle mass than fat mass then the calorie intake should be higher due to muscle demands.
