I’d find another surgeon honestly..mine didn’t require any weight loss or preop diet. I just couldn’t be heavier than I was at my first appt. hopefully you find someone to work with you. The surgery will surely help manage the diabetes better. Good luck!
I weigh daily. I only log a loss. I feel it helps me recognize trends and not obsess so much when I’m a few ounces more today than yesterday. I fluctuated with 3lbs during my first stall. Weighing daily helped me see it was just moving here and there and then took off again.
