Macro calculator: how to set protein, fat, and carbs

The simplest macro approach (that works)
- Set a calorie target (maintenance or deficit/surplus).
- Set a protein floor.
- Set a minimum fat level.
- Put remaining calories into carbs.
Useful tools:
Common macro mistakes
- No calorie target: macros without calories is guesswork.
- Protein too low: makes dieting harder and recovery worse.
- Fat too low: can harm satiety and adherence.
- Daily perfection: weekly averages matter more.
