Hello. When I was very sick with MG, decades ago, I recall that a heavy meal seemed to exacerbate my symptoms. However I’ve never noticed any other link between diet and MG, and have never heard anyone else make that link (but MG is such an under-researched condition that there could be an unknown link). The disappearance of my symptoms wasn’t a result of a change in my diet anyway. (No meat except in recent years chicken and fish, otherwise I eat anything). Good luck!
