Strong narratives and beliefs that often aren't really true can be a really effective method of weight loss and maintenance for some people. But I would say this isn't something "PhDs in nutrition" should be doing. https://twitter.com/BiggestComeback/status/1390764723906519041

If you are someone who cares about accuracy they can be really annoying and frustrating though. I think such narratives are often more effective the less true they are, which can be more annoying.

Radical changes to your health through diet often require radical changes to your diet. You often need to separate yourself form the food culture you live in, from all the marketing aimed at you, and from the food of your childhood, family, friends, and colleagues.

A strong, consise narrative to believe in helps you achieve and sustain that.

But only for what is probably a minority. It is hard to tell with strongly self-selected successful groups. When you are in one of those groups it really feels like you have discovered the solution to everything and you cannot understand why everyone else can't see it.

Not saying things can't improve. I've just been following this hole diet thing online since the late 90s. Gurus come and go, individuals adherents come and go, and few are still there years later.

It's a strange world that can seem influential but at the same often seems to have little lasting influence on wider society. At least in terms of improved health or weight loss.
