When I started my dieting career , I was 186lbs, I needed help because I didn't know how to diet. I used slimfast , only ate very little, then ate like a pig because I was too hungry. I kept going up and down too.. What really worked for me was going into a group called weight watchers.. You actually meet with people at these meetings and listen to others with their struggles and get some motivation, you learn something about portion control and food. This Weight Watcher thingy really helped me, That was 17 years ago when I joined.. kept the weight off since.
