Fat and protein are the ONLY ESSENTIAL macronutrients.
You are a physical being. A walking bag of chemicals in a physical reality with rules and laws.
These rules and laws are not like speeding on the highway. They are like gravity.
You don't get to not get caught.
Just like gravity, these laws are always in affect. Step off a tall building, and you're going down.
Carbs are not essential.
You can survive on only fat and protein. And you will die without them
There are things we can have opinions on. And then....there are things that no matter the resolve, desire or belief....it's just the way it goes.
