Goal Weight Calculator

Why Most Weight Loss Goals Fail

Research shows 80-95% of dieters regain the weight within 2-5 years. The problem isn't willpower - it's unrealistic timelines and unsustainable deficits that trigger metabolic adaptation and muscle loss.

This calculator gives you a sustainable timeline based on science-backed rates: 0.5-1% of body weight per week for fat loss. Slower progress = better muscle preservation, less metabolic adaptation, and permanent results. Our research chapter 1 explains why crash diets always fail.

Safe Weight Loss Rates

• 0.5% per week (Conservative): Maximum muscle retention, minimal adaptation
• 0.75% per week (Moderate): Balanced, sustainable, recommended
• 1.0% per week (Aggressive): Requires high protein, diet breaks
