Reply to comment by Sweet_Musician4586 in Aerobic exercise can reduce the risk of metastatic cancer by 72%. According to the researchers, intensity aerobic exercise increases the glucose (sugar) consumption of internal organs, thereby reducing the availability of energy to the tumor. by Wagamaga

Not necessarily. You can still produce glucose on keto.

Not only can you still produce glucose, your body will automatically manufacture it whenever it needs.

Your body keeps a tightly controlled range of glucose in the blood at all times. If that glucose is not from coming from food, your body will easily manufacture the glucose from whatever macronutrients it has available.

Unfortunately even a basal level of glucose is enough for cancer to use as fuel. But even if glucose production could be magically shut down entirely, cancer would be able to use other fuel sources available in the cell. This is why keto alone has not been shown to halt or cure cancer.
