1. Clinical Guidelines

Medical guidelines state that a safe and highly sustainable rate of fat loss is 0.5% to 1.0% of your total body weight per week. For an 80 kg individual, this translates to roughly 0.4 kg to 0.8 kg per week.

2. Risks of Rapid Loss

Losing weight too quickly (above 1.5% body weight weekly) triggers a protective starvation response, resulting in: Skeletal Muscle Catabolism: Your body degrades metabolic muscle tissue for energy. Hormonal Downregulation: Severe drop in thyroid output and sex hormones.
  • Rebound Gain: Intense psychological cravings that lead to binge eating.
