I am certainly no expert, but I did loose 40 lbs. on Weight Watchers in 1999. I have remained a lifetime member since then. What keeps me on track is weighing in faithfully each month. I know as long as I don't go over my goal weight by more than 2 pounds I don't ever have to pay the monthly meeting fee. Having to account to someone besides myself each month is helpful to me.
I begain biking since I lost the weight. It gives me one other way to keep burning calories and keep the heart in shape. I also became a certified scuba diver in 2000 at the ripe old age of 53. This is one grandma that is trying very hard not to rust.
