About the Calorie & Macro Estimator

Estimate your daily calorie needs and a rough macronutrient split based on your age, weight, height and activity level. Useful as a starting point for tracking, weight goals or meal planning.

These are estimates, not medical advice. Adjust as you learn how your body responds over a few weeks.

  1. Enter age, sex, height and weight.
  2. Pick your activity level.
  3. Read the estimated daily calories and macro breakdown.
