Fight Cancer with a Zero Carb Diet
Cancer cells are like greedy sugar addicts compared to normal healthy cells.
Proof of this is the PET scan used to detect cancer.
When you have a PET/CT scan, radiolabeled glucose, a form of glucose (or sugar) labeled with radioactive material, is injected into a vein.
Those greedy little cancer cells will quickly gobble up that radioactive sugar and that’s how the scan detects where the cancer is.
(They KNOW cancer gobbles up sugar, but still won’t tell you to stop eating it!!!)
Healthy cells in your body can use different fuels for energy: sugar (glucose from all carbs), fats, or ketones (which your liver makes when carbs are very low or zero).
But cancer cells have damaged "power plants" (mitochondria), so they rely heavily on a fast, sloppy way to burn sugar called the “Warburg effect”, they guzzle huge amounts of glucose, turn it into energy quickly and make lactic acid as waste.
Cancer struggles to use fats or ketones for fuel to grow.
When you eliminate carbohydrates (zero-carb or very strict ketogenic approach):
- Your blood sugar drops a lot because there's almost no incoming glucose from food.
- Your body switches to burning stored fat, producing ketones as an alternative fuel.
- Normal cells adapt happily, they use ketones or fats instead of glucose for energy.
- Cancer cells get starved of their favorite (and often only good) fuel: glucose. They can't easily use ketones, so they have less energy to grow, divide, and spread.
This glucose "starvation”, slows down tumor growth (seen in many animal studies and some human observations) and makes cancer cells weaker and more vulnerable to treatments like natural metabolic therapies, chemo or radiation.
If you have cancer, the first thing you should do is stop eating all carbs!
• Cutting out carbs will lower glucose.
• Cancer cells will go hungry while healthy cells thrive.
• Tumors often grow slower and in many cases shrink.
• Cancer treatments will work better.
This may not be a cure but it's why zero-carb/ketogenic diets are now seriously being studied as a supportive strategy, especially alongside medical care, to make the body a tougher place for cancer to thrive and grow. 🤔
