Because ketone bodies lower tissue inflammation and free radical production, studies show this could help prevent or improve neurological disorders and conditions, including brain cancer, Parkinson’s disease, traumatic brain injury (TBI), epilepsy, and Alzheimer’s disease.   A ketogenic diet has been shown to decrease tumor growth, especially when paired with intermittent fasting or caloric restriction. 
Research shows a high-fat ketogenic diet can also be beneficial for depression, migraines, and post-traumatic stress disorder. 
2. Nutrient Absorption
Vitamins A, D, E, and K are fat-soluble, which means you need dietary fat to properly absorb them during the digestive process. Without this essential dietary fat, you’re also missing out on these beneficial nutrients. Adding some form of fat to every meal can promote nutrient absorption! Fat-soluble vitamins like vitamin A provide health benefits, such as protecting vision. In fact, a deficiency of vitamin A can lead to blindness.  
Fats make you look good, too, and eating fat can make your hair shinier and stronger and accelerate hair growth! Your body needs fats to absorb minerals and vitamins that nourish your scalp from the inside.
3. Improves Cholesterol
Cholesterol’s been the talk of the town for some time now, and the topic is controversial and complex, to say the least. Growing research shows eating fats can actually increase the amount of ‘good’ cholesterol and lower the ‘bad’ cholesterol in your blood. Overall, consuming healthy natural dietary fat can improve cholesterol markers, another good reason to eat fat. 
Research also shows the cholesterol you consume in your diet has little to no effect on the cholesterol in your bloodstream. Eating more cholesterol from foods like eggs actually makes your liver produce less and stabilizes blood cholesterol.  Going keto can improve cholesterol!
