According to leading cancer researcher Dr. Thomas Seyfried, cancel cells cannot survive a keto diet. "Put your body into a state of nutritional ketosis—which is low sugar, elevated ketones and fatty acids—and the tumour cells will get hammered and they'll slowly degrade." "We have not found a tumour anywhere... that can survive without [glucose and glutamine]. As long as you can target those two fuels and transition the body over to a fuel the tumour cells can't use, they choke on it."
