Cancer Researcher Thomas N. Seyfried Shares 2 Approaches to Slow Tumor Growth

Most people think cancer is purely genetic, but research shows metabolism plays a massive role in how tumors grow.
In fact, one of the earliest studies demonstrated that high blood sugar accelerates tumor growth, while lowering glucose slows it down.
This is why scientists like Thomas Seyfried have proposed “metabolic therapy”, targeting the two main fuels cancer cells rely on:
Glucose and glutamine.
By lowering carbohydrate intake, fasting, and shifting into ketosis, the body produces ketones that healthy cells can use—but cancer cells can’t.
Over time, this can stress tumor cells, cut off their fuel supply, and shrink their blood vessels.
Important note:
This is still an emerging area of research and not a replacement for medical treatment.
But it raises a powerful question—what if nutrition and metabolism are as important in cancer therapy as drugs and radiation?

English Script:
Thomas Seyfried: Cancer is very preventable. It’s just that we’re doing everything we possibly can to induce it. We published one of the first ever papers linking that the higher your blood sugar, the faster the tumor grows. The lower the blood sugar, the slower the tumor grows. Undeniable. From a normal cell to a cancer cell doesn’t happen overnight. All we have to know with cancer is how are they growing so rapidly? Why are they going out of control? How come it’s so hard to kill them? A solution to the cancer problem without toxicity is to simultaneously restrict the two fuels. Glucose, which is already in our bloodstream from the food we eat and the amino acid glutamine. If we stopped eating and we took a low carbohydrate diet, just did water, only fasting, we would get into nutritional ketosis. The tumor cells have a bad mitochondria. They’re dependent on glucose and glutamine. We can replace glucose and glutamine with ketone bodies. So we selectively marginalize these tumor cells slowly over time, they slowly start to die. The blood vessels disappear and the body comes in and dissolves them.
