No doctor-ordered restrictions. I don't eat certain things that I know I shouldn't. Like, we very rarely eat fast food - I can't remember the last time - but it tastes like crap anyway....these days.
I eat things I probably shouldn't, though....occasionally. But my blood work looks good, I get a passing grade on all my physical exams, and my BMI is perfect, so I don't worry about it.
I'm too skinny, though, and I'm gradually getting skinnier. That bothers me a lot, so I make sure I eat something high-protein everyday, and I don't feel guilty for eating a candy bar or 2 once in a while.
