About Free Calorie Calculator
Estimate adult maintenance calories with Mifflin–St Jeor, or override the estimate with a maintenance value you already trust. Then add a transparent goal adjustment, control exercise calorie eat-back, create higher-calorie days without breaking the weekly budget, and split the result across meals and macros.
