A success story? I'm still in the making but I just wanted to tell you you can do it..I started low-graining at over 220lbs as well (started off more south beach then PB but whatever)..and I'm now under 155lbs. Just look at it as a journey, the destination will come. Also, check out the before and afters in the success story area..there are some amazing transformations to motivate you as well
