Imaginary fat

I was working with the trainer this morning.

Trainer: You've lost some weight.

Me: No, I'm still at 160.

Trainer: No,you're probably going to maintain that weight. You've lost some fat.

Me: Oh!

Either living on protein shakes, oatmeal and green vegetables for a couple of weeks helped more than I thought, or I am so far around the twist about my weight that I am beyond help.
