Total weight lost: 2 lbs (2 percent)

Waist decrease: 0.8 inches

"Alfie is a lot healthier now and much more active," his owner explained. "He's built up a lot of muscle. The vets tell me that muscle weighs more than fat and that's the reason why, although he's lost weight, he's struggled to lose more. He's not limping anymore and he's not in as much pain."
