Went from 290 to 245 in 6 months last year. I never really went to the gym, but I did play racquetball for like 2 hours 4 nights a week when I lost the weight. I started eating lots of salads, low carb sandwiches, and I was also taking some pills I bought on e-bay I'm back up to 265 because I stopped being active. Just started the same routine last week so I'm hoping to drop a pounds by the end of the year. I'm aiming @ 225 as my ideal weight. I'm 5'11"
Also, I gave up soda/pop during the time I lost the weight, I was drinking strictly water and unsweeteded freshly brewed iced tea. I heard somewhere that if you drink unsweeteded iced tea with your meals it cuts the fat in half (dont' know if it's true or not). Congrats to those losing weight, it takes a lot of determination and sacrifices...but it's well worth it, I know I felt healthier after losing the weight.
