Me personally... it's a bullsht gimmick... don't bother. You sure as hell ain't gonna starve his cancer to death. That ship has sailed. He has cancer... his cancer will convert anything in his body to be fed and to grow and to metastasize. It knows what to do... regardless of what he eats. And besides... there are plenty of places on our EC journeys we are up against weight loss. I advise hundreds of my fellow EC patients I counsel to pack on the weight any chance they get... as long as they can swallow and keep it down. During our chemoradiation treatments we often lose our taste buds... lose our desire to eat... have nasty nausea, etc. But if you can swallow... go get 'em! EAT EAT EAT! you're eating for survival... for all that is yet to come on your EC journey.
But I get it... sometimes we all want that mental edge... to believe how we're eating now is helping us to fight our cancer. Hogwash... stop losing weight and pack on those pounds... because looking like a corpse... freezing your ass off... feeling your bones just sitting on hard surfaces... many of us have been there! Not pretty! Be well!
