An honest timeline

Twelve weeks, because that is one season.

Every transformation programme is sold in twelve weeks. Not because bodies work in twelve week blocks, but because a quarter is a convenient thing to sell. Your timeline depends on how far you are going and how fast a body can safely go.

Weeks, the length of every programme

The same number of weeks whether you have three kilos to lose or thirty. It was chosen by marketing, not by physiology.

The arithmetic runs in your browser. Nothing is sent anywhere.

Method
Rates of 0.4, 0.6 and 0.8 percent of bodyweight per week, and roughly 7,700 kcal per kilogram of fat. Real loss is never this smooth: water shifts hide fat loss for weeks at a time.
Refusals
A goal that puts you under a BMI of 18.5 is not returned, and neither is a rate above 1 percent of bodyweight a week. Both are places where a clinician belongs, not a calculator.
