Losing weight on a GLP-1? Some of it is muscle. This tells you how much.

Ozempic, Wegovy and Mounjaro work. But studies put lean tissue at a fifth to two fifths of the weight people lose on them, and almost nobody is told. ForgeFit gives you your own number and the one thing worth changing first.

How it works
01
Seven questions
Weight then and now, how long you have been on it, age, height, protein.
02
An honest estimate
A range, not a false decimal — with the published formula shown next to it.
03
One thing to change
Usually protein, sometimes rate of loss. Something to take to your prescriber.
