With the move to more solid foods, I'm constipated (even using Benefiber) and the scale isn't moving. Time to buy a laxative! I posted this to verticalseevetalk.com and it seems like others are in the same boat. It seems to be the body's temporary reaction to a major change, after being on liquids so long. It just got used to liquids, and now I'm making a change. I'm doing all the right things food-wise (600-800 calories a day, high protein, low carbs/fat) , so I'm going to step up my walking (I'm not cleared for regular exercise yet) and see if that helps.
If this happens to you, don't get discouraged, it happens to a lot of people week 3 post-op. Just keep following the good habits and it should sort itself out. Ill keep you posted.
