What the result means
The result shows how aggressive your weight goal is. Moderate weekly change is usually more sustainable than extreme targets.
Weekly change = (target weight - current weight) ÷ goal weeks. Daily calorie adjustment ≈ weekly kg change × 7,700 ÷ 7.
Large weight changes may require medical guidance, especially with health conditions.
Example calculation
Moving from 80 kg to 72 kg over 16 weeks requires -0.5 kg per week.
Tips for better results
- Recalculate after your training routine changes.
- Use weekly averages instead of one-day results.
- Keep changes gradual so the plan remains sustainable.
