The I want to be able to do shit reason resonates with me. I used to play basketball at the local gym. However, I'm not going to participate unless I can participate well (don't want to embarrass myself).I am actively working to lose weight for health and "I want to be able to do shit" reasons. So far I'm down 110 lbs in the last 6 months. I did it by changing how I eat mostly, though I am more active now; it's a direct result of losing the weight and feeling better. I still have a long ways to go, but I am almost half way to my goal weight of 220.
