CLAIM: Ketogenic diets may enhance cancer treatment effectiveness

Diet & nutrition
Impact on cancer risk undetermined

What you may have heard Ketogenic diets (KD), which are high in fats and low in carbohydrates, can improve cancer treatment outcomes. What science tells us A ketogenic diet produces ketone bodies from fats, reducing glucose and insulin levels. This might help stop cancer cells from growing and promote their death through processes like ferroptosis…
