The keto diet has helped some diabetics get off their medication because of its stabilizing effect on insulin levels and lowering of blood sugar. Of course, we always recommend talking to your doctor before stopping a medication. The keto diet can also help with cholesterol levels by improving “good” HDL cholesterol. Because of its high healthy fat content, the diet has beneficial effects on the brain, which is at least 60% fat. Its anti-inflammatory benefits have been claimed to reduce the risk of Alzheimer’s and cancer. For many, the keto diet greatly increases their energy because ketosis creates more mitochondria, your cells’ tiny power generators.
