The ketogenic diet, or keto, is a low-carb, high-fat diet that can help with weight loss. Researchers are looking into how it may help with neurological diseases like multiple sclerosis (MS). MS is a disease that damages the protective covering of nerve fibers, causing nerve impulses to slow down. Early research shows that the chemicals called ketones produced by the keto diet might help repair damaged nerves and reduce inflammation. Keto changes your body’s energy source from glucose to fat, producing ketones in the process. These ketones may act as antioxidants, improve energy production in cells, and reduce inflammation. They might also help balance brain chemicals and trigger a cleaning process in the body to remove old, damaged cells. While keto shows promise in managing MS symptoms like fatigue, obesity, and depression, it can also cause issues like weaker bones and constipation. Always consult with a doctor before starting the keto diet, especially if you have MS.
