Still going

I'm getting away from logging food on here lately and i think its to the point now after 6 months i know what i have to eat to maintain and still drop lbs, im below my 30year weight of 200lbs high school 1984. im at 193.5 now was 260 4 years ago, my goal is around 180. I find with the cardio i do and alternating days of free weights my metaboliism has changed drastically and the food i ate before that put on the pounds now doesnt affect me, anyone else's thoughts on this would be appreicated.
