I had mine on 12/15/17 and at my appointment on 12/26 I had lost 22.4 lbs.. i will say it was easier to follow the diet than I thought through the holidays. I have my next appointment on the 23rd and just hope it continues to go in the right direction. The mush diet I'm on til then doesn't tend to sit to well though, mashed potatoes seem to sit way to long even at 2 ounces.
