Ketones are the greatest (legal) performance-enhancing "drug".
Your brain, heart, and metabolism greatly prefer ketones as a fuel source.
They are the reason you remain cognitively sharp while fasting.
Here's what everyone needs to know: 🧵
First off, what is a ketone?
It's a byproduct of fat being burned and serves as an alternative fuel source to glucose.
Think of ketones as your backup energy reserve when glucose is depleted.
Once that happens...
Your body will switch to ketosis. During ketosis, it will break down fats for energy releasing ketones. They energize cells and tissue so the body can keep working.
For example, your body can go into ketosis when you're:
• Asleep
• Fasting
• Exercising
• On the keto diet
