Because processed foods are associated with many health complications.

Sources to back your theorem on the cause of obesity?

You get obese since you eat too many calories. Humans obey thermodynamics.

Unfortunately it is a lot easier to eat too many calories on Cheetos and Doritos Locos tacos than less processed foods like salads.

I think your point on nutritious food being widely available for cheap is spot on.

That said going back to entropy to explain how a structure of dozens of trillions of cells harvest energy from foreign structures following a lifetime of heuristics is utterly misleading.

In particular it makes it sound scientific, when we have very little practical knowledge on how it works at scale and can't reliable do falsifiable experiments to prove our theories.

I mean, we're still literally burning stuff[0] as a proxy for the digestion process because we have no other way of coming up with a stable number. Which gives us aberrations like gasoline having higher nutritious value than potatoes (which totally makes sense in thermodynamics, I concur)
