A practical tool, a clearer next step

Macro Calculator

Turn a calorie target into an illustrative protein, carbohydrate and fat allocation.

The maintenance, fat-loss and muscle-gain presets set example protein/fat preferences; edit them for a custom split. Protein can be 1.4–2.0 g/kg and fat 20–40% of energy; remaining calories become carbohydrate using 4/9/4 kcal per gram. These are planning examples, not personalized prescriptions. Some combinations leave no carbohydrate and are rejected. Weight: 35–300 kg.

Method and source

For adults. These educational estimates are not a prescription, diagnosis or a plan for pregnancy, breastfeeding or a medical condition.

How to interpret the result

A macro split is a planning aid. Food preferences, tolerance, training and individual clinical needs can require a different allocation.

Common questions

No. Enter a calorie target first. The tool distributes that input; it does not independently establish your energy needs.
