Fairly good, actually. When my diet and training were at their best I gained a pretty good amount of lean mass. My strength gains always felt oddly lacking in comparison, though.
While I definitely ingest less carbs than the average American, I'm not too low. I have rice multiple times a week.
I'm at ~15% bodyfat. I've been as low as 10 recently.
I desire it and just can't perform.
When I was training as much as I wanted my mood was definitely at its best. The only downside to that was if I didn't make it to the gym for 3 days I could feel my mood and general state of mind going to shit overnight. Noticed the sexual problems ~3 years ago. Mood problems for probably 5 years but they didn't seriously worry me until 2 or 3 years ago.
Thanks for all your input guys.
