At 5 months post-op I had lost a whopping 40 pounds...
However, my frustration about the slow rate of weight loss dissipated long ago. I took 17+ months to lose 100 pounds and attain my goal weight.
So, yes, I was surely a slower loser. Nonetheless, I've been maintaining my loss nicely and that's what matters. In the past, prior to surgery, I would have regained it all plus more.
Good luck to you...realistic expectations are helpful in your journey.
