In this video, I want to talk about why the statement, "your brain needs glucose" is a myth. The brain doesn't need to run on glucose (sugar and carbohydrates). If it did, how would you explain the people who cut out all carbs and sugars?

You only have 72 hours of fasting glucose before your body is tapped out of glycogen (stored glucose). What happens when there's no glucose? After your glycogen stores are gone, your body starts to run on a different fuel source: ketones.

The body converts stored fat into ketone fuels. This is known as the metabolic state of ketosis. Burning fat is actually much healthier than burning sugar. The brain prefers ketones over glucose. Some research even shows it can help prevent or improve dementia, like Alzheimer's.

Running on glucose can cause insulin resistance. It's my personal belief that insulin resistance and dementia are related. This would explain why so many diabetics have problems with dementia and memory loss.

Ketosis and ketoacidosis are completely different things. Ketoacidosis is a problem that happens when you're diabetic, where your body's pH level is thrown off. This creates a lot of side effects. Ketosis is a healthy state—unlike ketoacidosis.

Many are concerned about ketosis side effects, like bad breath, digestive problems, etc. However, these problems don't happen if you consume enough healthy vegetables. You need vegetables to keep your body healthy and nourished.

The ketogenic diet is one of the best diets you could go on for weight loss and health.

Also, keep in mind that consuming fat doesn't raise your cholesterol unless you also consume sugar and carbs. When you consume more cholesterol foods, your body simply makes up for it by creating less.
