How much muscle might you lose in 3 months of not lifting

Curtism1234

I suffered a bad back sprain in June and haven't been able to lift weights or run since then.

I did go on a diet to keep from gaining weight. I am losing pounds but I don't know if it's fat or muscle.


So my question is - how many pounds of muscle is an average 28 year old male likely to lose in 3 months?
