Cancer can only metabolise glucose
Carbohydrates of all types turn into glucose.
Humans can live without eating carbohydrates.
Going strict zero carb (carnivore) will stop feeding the cancer extra fuel, reducing the growth rate. For some people this is enough so their own bodies can get ahead of the cancer.
This makes carnivore a great ADJUNCT to a cancer treatment plan. By itself carnivore will not cure cancer.
Without medical intervention the body will still make glucose, which cancer can use. This production is at a much lower rate then eating carbs. There is a human trial testing cancer protocol that presses of zero carb eating with pulses of drugs that stop the bodies glucose production. The studies that use this focus on glioblastomas in the brain and show very promising results (in humans, not mice)
Tldr: carnivore doesn’t cure cancer, but it doesn’t enable cancer either, it couldn’t hurt to go zero carbohydrate while fighting cancer.
— a shower thought, since I’ve been talking to my friends about cancer seemingly over and over. Every body knows somebody fighting cancer


There is a lot of well-deserved skepticism out there when it comes to the effects of diet on cancer outcomes, and understandably this post has been heavily downvoted.
