The human gut evolved to thrive on fermentable fibers, not bacon cheeseburgers:
That huge array of dietary fiber supplements in the drugstore or grocery aisle can be overwhelming to a consumer. They make all sorts of health claims too, not being subject to FDA review and approval. So how do you know which supplement works and would be best for you?
A rigorous examination of the gut microbes of study participants who were fed three different kinds of supplements in different sequences concludes that people who had been eating the least amount of fiber before the study showed the greatest benefit from supplements, regardless of which ones they consumed.
[...] The benefit of dietary fiber isn't just the easier pooping that advertisers tout. Fermentable fiber -- dietary carbohydrates that the human gut cannot process on its own but some bacteria can digest -- is also an essential source of nutrients that your gut microbes need to stay healthy.
[...] When your gut bugs are happily munching on a high-fiber diet, they produce more of the short-chain fatty acids that protect you from diseases of the gut, colorectal cancers and even obesity. And in particular, they produce more of a fatty acid called butyrate, which is fuel for your intestinal cells themselves. Butyrate has been shown to improve the gut's resistance to pathogens, lower inflammation and create happier, healthier cells lining the host's intestines.
[...] "We didn't see a lot of difference between the fiber supplements we tested. Rather, they looked interchangeable," David said during a tour of his sparkling new lab in the MSRB III building, which includes a special "science toilet" for collecting samples and an array of eight "artificial gut" fermenters for growing happy gut microbes outside a body.
[...] "It doesn't need to be a supplement either," Holmes added. "It can just be a fiber-rich food. Folks who were already eating a lot of fiber, which comes from plants like beans, leafy greens, and citrus, already had very healthy microbiomes."

Reengineer the gut to deal with the changes in food intake.
Evolution has to become survival of the fattest!

I'm all for gmo humans. Figure out how to isolate that Scandinavian skinny gene and into a therapy. That's one vaccine I'd take.

While we're talking about GMO humans, lettuce not forget survival of the dumbest. They need to breed like rabbits because they learn 'abstinence' in high school. The smarter people will not breed as much. Thus selection pressure.
Speaking of lettuce, one weigh of losing wait is to eat healthier foods instead of supplements. Imagine that! My wife and I discovered this since covid-19 started. We got groceries delivered to our door and began eating healthier. Without realizing it at first we began losing weight.
