Personalized Macro Targets
Updated February 28, 2026
Personalized macro targets size protein, carbs, and fat for your goal, body size, training, and schedule. Start with Understanding Macros if you need a refresher.
Calculation
| Step | Rule |
|---|
| Protein | 1.6–2.2 g/kg body mass |
| Fat | 0.6–1.0 g/kg |
| Carbs | Fill remaining calories after protein and fat |
| Distribution | Spread protein over 3–5 meals; move carbs toward training |
Signal set for valid updates
| Signal | Use condition | Why required |
|---|
| Adherence trend | at least two weeks of consistent logging | avoids one-week noise |
| Weight trend | stable windows without hydration shocks | protects overreaction |
| Sleep score | at least several low-friction days | supports meaningful output interpretation |
| Activity signal | repeated session load pattern | aligns metabolism with demand |
Recalculation rules
| Window | Rule |
|---|
| 2 to 4 weeks | review before any major shift |
| 6 to 8 weeks | hold unless three signals align |
| adaptation windows | move one macro block at a time |
Confidence threshold
| Confidence state | Action |
|---|
| Strong | one controlled update and monitor |
| Moderate | hold for one more cycle before change |
| Weak | freeze targets and improve tracking context first |
Fuel updates targets using your macro budget and current calorie targets, with adjustment logic similar to adaptive calorie goals.
