I see this a lot with dietary guidelines: people start talking about how they aren't based on evidence and they're useless and crap because people are still gaining weight

But the evidence-base of an intervention is separate from its affect. We can argue at length about whether dietary guidelines succeed, or are useful, but calling them evidenceless is simply a factually incorrect thing to say

A good example, funnily enough, is the ketogenic diet. The evidence base is pretty decent: in theory, it should work. In practice, it doesn't do much better than most other diets

Definitely. My usage of words varies widely from audience to audience; I often say things in my blog that I'd get excoriated for in scientific papers, but whether something is a "fact" or not is one of the hardest things to decide
