You are doing great business Stuco! By the way, I lose weight easy at 2,200 cals per day, and I'm only 5ft 8"! Mind you - it also depends on your lifestyle, ie how busy you keep yourself throughout the week, how much energy that you use at work, how many hours, how much you walk/cycle around, what kind of work, how much exercise etc. 1,500 was definitely too low for you!
You're doing great, keep it going!
