This is about as useful as telling someone who's obese to just eat less. Factually yes, it might help them, but practically they're clearly unable to implement it, probably for a plethora of underlying reasons.
Go see what people are eating in real life. There are a lot of studies.
Americans eat way more meat, almost no fruits and vegetables, and a lot of carbs.
The point is that the food pyramid has absolutely no impact and pointing to it and making correlations with it is like doing astrology to explain why you broke your hand while playing basketball the other day.
Edit: you do a great job to illustrate how little anyone knows about these food guidelines.
It took you 17 years to even learn they’ve changed.

I gave an age range for a very specific reason: That's the age group this food pyramid was pushed hard on kids. I didn't know it changed because I was finishing gradeschool as the change happened.
You don't have to memorize and precisely follow it to have internalized generic things like "lots of carbs = good". They are supposed to be our bodies' main source of energy and there's really no way you can have too much (or so we were taught at the time).
Implementing a ketogenic diet is not the same as a caloric restriction diet - it’s an inversion of the macronutrient pyramid - heavy on fat, moderate on protein and low on carbs.
Even if you consume the same calories as in a traditional diet you’ll likely lose weight. Check the https://metabolicmind.org site for more insightful information.
