Stop in for a cup of coffee

I have been eating only two meals a day for years now. I will eat breakfast before 9:00 a.m. and then not eat again until dinner time. No later than 7:30 p.m.. works for me. I can eat anything I want including carbs, and chocolate and ice cream, and drink all the beer I want as well. My weight doesn't change anymore than three or four pounds either way in the last 30 years. Don't know why?
Oh I still have ice cream and a toddy or two.
