Many diseases are a natural result of the aging process. While there have not been studies done on humans, studies on mice have shown brain cell improvement on a keto diet.
Several studies have shown a positive effect of the keto diet on patients with Alzheimer’s disease. What we do know is that a diet filled with good nutrients and antioxidants, low in sugar, high in protein and healthy fats, while low in carbohydrates, enhances our overall health. It protects us from the toxins of a poor diet.
There is also research indicating that using fatty acids for fuel instead of sugar may slow down the aging process, possibly because of the negative effects that sugar has on our overall wellbeing.
In addition, the simple act of eating less and consuming fewer calories is a matter of basic health, as it prevents obesity and its inherent side effects.
So far, studies have been limited. However, considering the powerful positive effects of the ketogenic diet on our health, it is logical to assume this diet will help us grow older in a more natural way while delaying the natural effect of aging. A normal western diet laden with sugars and processed foods are certainly detrimental to warding off the signs of aging.
