Why not, though? Eating is fun and pleasurable. If we can figure out a way to eat the things that we want, in the quantities that we want, while maintaining our health, why shouldn't we try?
I've lost weight through forcing myself into a calorie deficit, and it works really well, but it's not particularly fun.
You always end up with the people pushing these foods being those who sell them. And then others start selling fake foods with similar claims.
For the "eat to get slimmer" claim, I think we're at the point where "extraordinary claims require extraordinary proof."

What do you mean by "these foods"? Just buy unprocessed food and 99% of the problems disappear. There is no fake, no people trying to sell you these out of malicious intent. Just buy local food people had access to in 1900 and you'll cure all your problems.
