We have been hunter gatherer for a couple of hundred thousands years, and farmers for a couple of thousands.
I’d be wary of leaning too hard into this kind of argument, because our evolutionary history goes back more than a hundred thousand years.
Homo Habilis are currently believed to have been opportunistic scavengers at best, given that they weren’t adapted well enough to running to do persistence hunting.

While Australopithecine were straight-up herbivorous:

And hominid species earlier in the line were probably frugivores.
So a fuller version of this story would be that we have millions of years of adaptations to eating fruit and tubers, followed by millions of years of adaptation to also eating meat (initially sporadically and opportunistically, and later through more systematic hunting), followed by [at least tens of thousands of years of adaptation](https://www.sciencedirect.com/science/article/pii/S0899900722001150) to eating grains and dairy ([possibly including the genes that cause celiac](https://www.acsh.org/news/2015/07/08/scientists-think-they-have-an-origin-story-for-celiac-disease#:~:text=Furthermore%2C%20evidence%20implicates%20at%20least%2040%20genes,of%20celiacs%20disease%20is%20a%20good%20one.)).
While all the hunter-gathers in your table eat meat, the table also tells you that they all eat carbs whenever they’re available in the environment. A large part of our success as a species was our ability to adapt to and thive on many different kinds of diets, from almost vegetarian to almost carnivorous.
The Hadza reportedly get [10-20% of their calories from honey](https://en.wikipedia.org/wiki/Hadza_people), and in interviews with people who have lived with them I’ve heard that they prioritize honey even over meat ie even while tracking they’ll risk losing their prey if they see a beehive. They need the calories to get through the dry season.
I don’t think we have any numerical records for the Coast Salish, but their traditional foods seem to be pretty heavy on berries, both as sauces and dried in big cakes.
EDIT I’m not sure why only the first paragraph got parsed as markdown, or how to fix it.
My wife coaches teen athletes and the signs she’s taught to look out for are not weight loss but withdrawal, depression, poor digestion, feeling cold etc. Not to say that you’re doing something unhealthy, just that low mood is a known effect of being in an extended calorie deficit and not necessarily an effect of the semaglutide.
As you go further into deficit you tend to downregulate other stuff (eg bone and tissue maintenance) before losing weight faster, so the amount of weight loss only gives you an lower bound on your deficit. It might be worth tracking your calories and seeing how much more you can eat before your weight loss stops—you might find that a higher intake gives you better mood while still losing weight.
