Goal Weight Calculator
Calculate an ideal goal weight based on target body fat percentage
Assuming preservation of your 64.6 kg lean mass (~166 lbs)
Mathematical Formula & Scientific Methodology
Formula: Lean Mass Preservation Target Weight Formula
Goal Weight = Lean Body Mass / [1 - (Target Body Fat % / 100)]Provides a physiologically sound target based on your actual anatomical muscularity rather than arbitrary height-weight charts.
Model Assumptions
- Sufficient protein and resistance training to preserve lean tissue
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| Lean Body Mass | Weight × (1 - Current BF% / 100) | kg |
| Target Body Fat % | Desired body composition endpoint | % |
Scientific Limitations
- In very aggressive cuts, some minor loss of glycogen and water from muscle is normal
