What does ketosis do to cancer cells?

• A. It deprives them of glucose they crave in order to grow
• B. It reduces glucose supply to tumors
• C. It increases tumor glucose uptake
• D. It stimulates angiogenesis to support growth

Answer: (A)

Ketosis shifts the body's energy source from glucose to ketone bodies. When carbohydrate intake is low, plasma glucose and insulin fall and the body produces ketones for energy. Many cancer cells depend on high glucose uptake and glycolysis to fuel rapid growth. In this state, the available glucose is limited, creating energy stress for those cells. Ketones can nourish normal cells, but cancer cells often struggle to efficiently use ketones due to metabolic changes, making them more vulnerable when glucose is scarce. So, ketosis deprives cancer cells of the glucose they need to grow. It doesn’t increase tumor glucose uptake, and it isn’t known for stimulating angiogenesis to support growth.
