In session number 3 we went deeper into Ketosis:
What is it? Why do we want to go into it? How do I get into it? How do I know I'm in it?
Your body (brain) can run on either glucose or ketones. Glucose is sugar, while ketones are what your liver turns fat into in the absence of available glucose.
It can either turn your dietary fat into it (butter, avocado, etc.), or your body fat into it (yes, that pudgy stuff on you!), or alcohol into it. We train our bodies to more efficiently burn fat via eating dietary fat with no glucose in sight, so we can then let it burn baby burn! Say goodbye to those fat rolls.
