Zero carb is getting (relatively) popular. A handful of valued MDA forum members eat little-to-no-carb, and several others probably imagine it’s ideal even if they don’t personally follow it. I wanted to address this because there seems to be some confusion as to how a zero carb eating plan relates to the Primal Blueprint eating plan. To begin with: I think zero carb can be a viable option for some, but highly impractical for most. If one had access to and ate different animals, all range fed and without pollutants, and if one ate all offal (and stomach contents) it’s possible to approach zero carb… but again highly impractical. If you really, really love meat and fat and offal, and get genuine enjoyment from eating nothing but meat and fat and offal, have at it. On the other hand, if you are looking for a wider variety – and gustatory enjoyment – of the foods you eat, zero carb may be unenjoyable, impractical, unnecessary, and at worst (if not done just right) downright dangerous.
Let’s take a look at just a few of the reasons why vegetables are a part of The Primal Blueprint:
I’m trying to understand how glucose that’s created by proteins and fats is used and stored. Is that ~200g of glycogen stored in the muscles to be used for exercise, or is it stored in the liver and used to fuel the brain and “day-to-day” functions? Also, if muscle glycogen is depleted, will ingested carbohydrates be used first to replenish muscle glycogen and then to fuel other daily functions, or are they used the other way around? I’d like to be able to use ketones to fuel my daily activity, but still have enough muscle glycogen stores to fuel intense exercise.
What are ketones? How does ketosis play into the Primal Blueprint? Did our bodies evolve to run on ketones? If not, why do they exist?
Ketones, to put it briefly, are compounds created by the body when it burns fat stores for energy. When you consume a diet very low in carbohydrates, the body responds to the significantly lowered levels of blood sugar by flipping the switch to another power source. The body converts fatty acids in the liver to ketones. Ketones, then, become the main energy source as long as blood sugar levels remain low.
