I've read that caloric intake for a bypass patient at that month mark is not unusual. However, if you are more active than the normal bariatric patient, it is possible you are burning so many calories that your body is experiencing more of a caloric deficit than your dietician has estimated for you. Some dieticians are VERY good at individualizing their care to each patient's intake, activity, and dietary needs. Others stick to the book and will give everyone the same plan regardless of how many calories they are burning. That can be a detriment to you if you are burning more. If you are walking several miles a day, or intensely working out, you may need more protein than your current calories are allowing for. It might be worth messaging your dietician to ask if they took this into account. Stalls definitely happen, I had one last 6 weeks pretty early out after surgery, and I'm losing a little slower than I like, though they say it is right on target so I'm making my peace with that. It is good to stick to the plan you are given by your team, just make sure that plan is taking into account the whole picture of YOU, not just what patients average in general. Many bariatric patients are quite sedentary and averages account for that, not for active patients.
