Weight Loss Timeline Calculator
Unlike static 3,500 kcal models that assume linear loss forever, this calculator models realistic fat loss, acknowledging that as body mass decreases, energy expenditure naturally drops.
Your estimated daily maintenance energy (TDEE).
*Clinical estimate. Adjust gradually based on observed 14-day body weight trends.
Formula & Calculation Methodology
Integrates starting weight, target weight, daily calorie intake, and progressive metabolic reduction (~15 kcal per kg lost) to calculate expected goal completion dates.
Practical Example & Interpretation
To lose 10 kg starting from 85 kg at a 500 kcal/day deficit, expected healthy timeline is approximately 20 to 24 weeks with progressive metabolic recalibration.
Assumptions & Clinical Disclaimers
Scale weight fluctuates daily due to water retention, sodium, and bowel transit. Measure 7-day rolling averages rather than reacting to day-to-day changes.
