Yeah, basically disinterested. Somewhat burnt out from doing things I normally love doing such as going on walks, programming on weekends, gaming, and work. It wasn't a really big problem, I only noticed it when looking retroactively at my experience.

How much of that is just from your hormones being trashed due to a severe deficit?

Large caloric deficits (1000+/day) in leaner people is known to tank T levels among other things. When I was on such large deficits, I had very weird mood/arousal swings. Nothing that problematic for someone with as much executive control as me but it was very weird to be held hostage to.
