I pretty much stick to fish and veggies and grains now, no red meat, chicken, etc. I do pull ups, sit ups, pushups three times per week, take a run three times a week and take a walk for 30 plus minutes during lunch everyday. On the weekends I try to do a 5 mile walk with my pack in the forest preserves.
My biggest issue is eating pizza. I just can't stay away from it.
