Began with HMR back in 2007, wanting to lose weight to prepare for knee replacement surgery. I lost 100 pounds, and in 2009 had my first (left) knee successfully replace; then suffered a setback medically that required me to go onto a steroid medication that caused immediate weight gain again. Kept at it, though, and limited my weight gain to about 25 lbs. . . but then slowly gained some more, especially after the 2nd knee replacement in 2010. So I rejoined HMR, and am now in Phase 2, where I've lost about 15 pounds and am working on losing another 20 to 30.
