Work out teen calorie needs instantly with clear inputs, formula shown and shareable results.
Uses the Schofield equations for the 10 to 18 year age band and applies an activity factor, with a growth-supporting protein target.
Schofield equations (10 to 18 years)
Boys: BMR = 17.5 x weight + 651. Girls: BMR = 12.2 x weight + 746. Energy needs = BMR x activity factor
