We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Assuming this will be somewhat safer than bariatric surgery, we'll all be able to eat all we want and as inactive as we want, and we'll all be as skinny as models. Being in shape will lose all of its virtue because it will be effortless.

Any generalised removal of a health danger is a good thing. Everything has consequences, though. We will use some different attributes of attractiveness to differentiate each other when seeking mates (or even friends), and we won't necessarily all feel cheery about the results.

Your 'Assuming', likewise assumes that all their hypotheses about our digestive systems and metabolisms, and how our bodies myriad systems work, are correct.
