I've lost 9 lbs!

Eversince my doctor told me that I am close to being a diabetic. I went straight to diet. I haven't had a coke in 3 weeks! And I lessen the carbs that I am eating. It's a good thing that I don't have problems with my cholesterol yet, so I can eat as much meat as I can. During these 3 weeks, I've lost 9 lbs already! This just show that one doesn't need those fitness equipment to lose weight.
