Just to weigh in (no pun intended) with my experiences. I had a long time of inactivity, based around mainly being a nights only manager in an office job. I started Brazilian Jujitsu in April, didn't really change my diet which wasn't great but certainly wasn't "bad", and was at about 185-190 in December.
Seriously, just cut down on the beer, and train. Its really that simple.
Anyone know the quickest and best way to lose weight fast? Been layed up for about 7 monts with knee surgery etc and have wacked on around a stone and a half. Still not able to do any weight bearing on my knee or swimming and bending it is a bit painfull. Any help will do guys and girls
