I’m not new to keto (even though I’m newly back, again). And I assume that since I’ve been reading, on and off, everything I can get my hands on over the years, that I know the science behind it. WRONG. I was trying to explain to a curious friend the other day the basics of eating a keto way of life, and why I was testing my blood, and I realized I didn’t know what I was talking about. Yes, I know we try to stay within our individual macros. I know about switching from carb burning to fat burning, I KNOW about keto flu and why, and I know ketone levels fluctuate.
What I don’t remember (or never knew?) is: isn’t a ketone a byproduct of our bodies burning fat? I thought it was produced once we were in ketosis, and the number on the meter showed us how MUCH fat we’ve burned recently. But then I have to ask, why does anyone try to artificially increase their ketone levels by adding them with a supplement? (Yes, I have MCT in my cupboard but never did use it). What is the point of adding ketones to our system when our systems can and should make their own?
I’ve been searching for the answer but not finding it… yet. Can anyone help in layman’s terms?
