I get it, and it makes sense and so I have no sophisticated explanation of what our diets should look like. It's just that I've met so many fat people constantly avoiding carbs and too many skinny people who ate lots of them. I'm not here to knock your diet I just really miss that German.
I can't speak for hunter gatherers. But look at Japan, lots of carbohydrates and the rice with every meal meme, and they're the thinnest first world country because they don't have a culture of constant consumption of red meat/saturated fat. Sardinia is another good example of thin people who sparingly consume saturated fat but eat lots of noodles yet have obesity levels lower than a lot of our countries. The US isn't as fat as it is because of the bread/noodles/rice they're eating.
Personally, I was a chubby fuck when I thought of carbohydrates that way and have been much more slender since took what that German said in.
But if it works for you, go for it.
