I made a chart from the day of surgery to one year. I track my weight on this chart every week from the day of surgery so my weigh in day is on Mondays as I had my surgery on a Monday. It keeps me on track and I can track my one year post op journey. I do sometimes weigh during the week but I only record my weight on my designated weigh in day. I'm 9 1/2 months post op and I've lost 105 pounds. The scale can be a friend or foe just try to follow the doctors plan and I would say weigh once a week. Good luck!
