Just wondering if anyone else out there has had bypass and gained weight back. I have not gained it all back, but a big percentage. And does anyone know if this will affect the Primal diet? I have been Primal strictly for 5 weeks, losing only 5#. I feel better and don't intend to leave Primal, but just wish the scales would show progress. I can tell a difference in my clothes. I know I should be patient, but after 3 weeks of not losing, I think that is patience enough. Please can anyone help me??? I have posted to several forums here without response. I even emailed Mark, thinking an assistant or someone would/might respond. well, Mark did! He told me to do the things I have been doing anyway. One more try here.
