I am in the same boat with you. Dr said between weeks 3-5 it will stall out then pick back up. I’m 4 1/2 weeks post bypass and only lost 16 since surgery. I have lost inches and forgot to measure before I started my journey. But I did measure a week ago so I know going forward. I did take before pictures and current pictures and can tell a difference. That what I look at to keep me going so that I won’t worry about the scale. All this protein is helping to build muscle and it weighs more than fat.
