This is one of the most fascinating podcast episodes I have ever listened to.
One interesting moment in particular—as someone whose roommate survived cancer and chemotherapy—was when Doctor Seyfried discussed the notion that targeting cancer’s main source of fuel (glucose) could be just as effective as chemotherapy. So cutting out sugars from someone’s diet could prolong or save their life without destroying their quality of life.
Check out the podcast from either their page or from Overcast.fm, which has a very nice, easy player.
