If it was doing IIFYM, it didn't drop carbs, so not much water weight lost. 2-4 lbs/week is pretty standard for successful weight loss, so it's a bit slow in that race. However, it's likely to be a lie because (1) no way it lost 12 inches with just 8 lbs, and (2) there was supposed to be hanging skin in the after pic, but, yet, the skin is even tighter (?).
