ReachWeight is a free, science-based weight goal calculator that helps you understand exactly when you can reach your target weight. Unlike simple calculators that use the outdated "3500 calories = 1 pound" rule, ReachWeight accounts for metabolic adaptation, BMR, TDEE, BMI, and three realistic scenarios: Safe, Moderate, and Aggressive.
| Scenario | Weekly Weight Change | Monthly Change | Recommended For | Risk |
|---|---|---|---|---|
| Safe | 0.5 – 0.7 kg (1–1.5 lb) | 2–3 kg (4–6.6 lb) | Long-term sustainable progress | Low |
| Moderate | 0.7 – 1 kg (1.5–2.2 lb) | 3–4 kg (6.6–8.8 lb) | Most people with good adherence | Medium |
| Aggressive | 1+ kg (2.2+ lb) | 4+ kg (8.8+ lb) | Short-term goals | High |
