![]() ![]() In response to this restriction, your body will begin to start producing ketone bodies that have many protective effects. It will begin to use fat for fuel instead of the glucose that’s derived from carbohydrates. This shift in calorie sources causes your body to shift its metabolic pathways. In the keto diet, you get about 75 percent of your daily calories from fat, and 5 to 10 percent of your calories from carbs. “By not overwhelming the body with an external load, it gives the body a break to focus on its own health and repair.” “Ketosis, a diet high in fat and low in carbs brings the same benefits of fasting without fasting, like a shortcut to induce the same beneficial metabolic changes,” she adds. ![]() “Fasting is most effective way to trigger autophagy,” explains Petre. Remember that autophagy literally means “self-eating.” So, it makes sense that intermittent fasting and ketogenic diets are known to trigger autophagy. Researchers believe that new studies will lead to insight that will help them target autophagy as a therapy for cancer. “Recognizing and destroying what went wrong and triggering the repairing mechanism does contribute to lowering the risk of cancer.” “This is how the body polices the cancer villains,” she explains. While there’s no scientific evidence to back this up, Petre says some studies suggest that many cancerous cells can be removed through autophagy. That’s why some researchers are looking at the possibility that autophagy may lower the risk of cancer. While all cancers start from some sort of defective cells, Petre says that the body should recognize and remove those cells, often using autophagic processes. “Autophagy declines as we age, so this means cells that no longer work or may do harm are allowed to multiply, which is the MO of cancer cells,” explains Keatley.
