Boho, you can eat whatever you want. Anything you eat will have consequences, some good, some bad.
The idea is to eat with intent, so that you make your nutritional decisions based on the consequences. An important consequence is your own enjoyment or satisfaction. If you are able to align your own satisfaction with good nutrition, that is what you should do.
I do this by eating meats, eggs, a little cheese, drinking milk occasionally (between 1/2 gal and 1 gal per week), coffee, and very little else. This translates to what is accurately called an ultra-low carb diet, which shifts the body chemistry into a state of ketosis where fats are burned for energy, not sugars.
This approach seems to well for me. It has simplified a lot of things, especially the consequences of ingesting various things.
Are there ways to improve my nutrition, even within this narrow diet? Sure. Food preparation methods, harvesting methods, even the stress level of the animal providing the food can have nutritional effects. I'm not trying to develop the perfect diet, though. I just want to eat with intent, and be informed in my decisions.
When I said that keto has a lot to learn, it wasn't intended as a personal attack. I think keto might be a great place to start really paying attention to what you eat. Unfortunately, most people who try keto either don't get the results they hope for, or never kick the sugar addictions. Some at least get the feeling of having consistent energy levels, and this is enough to keep them thinking there could be something to the whole keto thing, causing them to revisit it.
I actually see it a lot like the bitcoin adoption path. Most don't go all in on bitcoin and stay there, from first exposure to self-described bitcoin maxi. Most get teased back to fiat, shitcoins, diversification, taking profits, etc., then eventually come back around to enjoying the simplicity of hard money.
So I see keto as the Coinbase or Robinhood of low carb diets. And there's a lot to learn as you go down the rabbit hole of dietary sovereignty.
Love you, boho! I know you are more aware than most of your own biology, more aware than I am, and you act with intent, so you are already well on your way with all of this. Don't let me hold you back with my disagreeableness!
