| Fasting Protocol | Daily Fast Duration | Avg Weekly Loss (Metric) | Avg Weekly Loss (Imperial) | Primary Benefit |
|---|---|---|---|---|
| 14:10 | 14 Hours | 0.4 – 0.5 kg | 0.9 – 1.1 lbs | Gentle entry; easy adaptation. |
| 16:8 | 16 Hours | 0.6 – 0.8 kg | 1.3 – 1.8 lbs | Gold standard; long-term fat loss. |
| 18:6 | 18 Hours | 0.8 – 1.0 kg | 1.8 – 2.2 lbs | Enhanced oxidation & autophagy initiation. |
| OMAD (20:4) | 20 – 23 Hours | 1.0 – 1.4 kg | 2.2 – 3.0 lbs | Rapid fat loss & maximum HGH surge. |
Our mathematical model calculates projected dates based on standard metabolic oxidation rates and healthy weight loss guidelines (0.5 to 1.2 kg per week). Individual timelines vary slightly based on age, thyroid function, muscle mass, and compliance.
Medical consensus recommends aiming for 0.5 to 1.0 kg (1 to 2 lbs) of fat loss per week to ensure weight loss comes from fat stores rather than muscle tissue.
Plateaus are normal. Recalculate your current weight, increase daily step count by 2,000 steps, or shift from a 16:8 schedule to an 18:6 window to restart momentum.
