I'm 6'2" and I find that if I get below about 185 people start asking me if I'm unwell. A few years back I got down to about 178 and a few people asked my wife if I had cancer and wasn't telling anyone.
I dropped three pounds today just by not stuffing my face with cake and ice cream. My body seems happy to get rid of the fat it accumulated over the weekend. I hope to be back to my normalish 190 by mid-next week.
