When going to the gym three times a week for two years did not do anything for the weight (perhaps kept me from gaining more once I retired), I decided to get serious about loosing 50 or 60 or 70 pounds. 12 down and lots more to go. Low carb diets work for me - I had lost 40 pounds on Atkins 25 years ago, kept most of it off for a few years, but eventually put back those pounds and lots more. Trying South Beach this time, a modified Atkins that lets you eat some whole grain carbos in small quantities and limit the fats. If I keep this up for a year, I should be in good shape.
