Counting Calories vs Tracking Macros (Singapore)
Calories drive weight change; macros drive body composition. Beginners do fine counting calories; people training seriously should track both.
Feature Comparison Table
| Feature | Counting Calories | Tracking Macros |
|---|---|---|
| Tracks energy? | Yes | Yes |
| Tracks protein? | No | Yes |
| Effort | Low | Medium |
| Protects muscle? | Not directly | Yes (via protein target) |
| Best for | Beginners | Lifters & athletes |
Comparison Verdict
Start with calories. Once you're consistent, add a protein target. If you train hard, track all three macros.
