How the estimate works

The calculator uses simple goal-based multipliers and common macro targets to create a practical starting point.

Protein first

Protein is estimated from body weight to support satiety, recovery and training goals.

Goal-based calories

Lose, maintain and gain modes use different calorie multipliers to match the selected goal.

Simple planning

Use the numbers as a starting point, then adjust weekly based on real progress.
