How Long To Lose Weight

A quick way to estimate weeks and months to your goal — based on your pace and current weight.

The math

Weeks to goal = (current weight − goal weight) ÷ weekly pace. At 0.5 kg/week, losing 10 kg takes about 20 weeks (roughly 4.5 months).

Tips to actually get there

  • Pick a pace you can hold for months, not weeks
  • Weigh yourself the same time each day, average weekly
  • Strength train 2–4× per week to keep muscle
  • Plan a maintenance break every 8–12 weeks
