Always been that way, always will be I guess. Someone happens on a set of very specific behaviours they use to fix some aspect of their behaviour/health/etc. Sometimes delusional, sometimes not, sometimes fake, sometimes not. Normally taps into something that seems "common sense". They or someone else sells it as a more general fix. Rinse and repeat. Just taps into a human need to find simple solutions? Diets, self-help, temperance, etc etc etc. Sometimes descends into cult-like behaviour, sometimes goes other way -- origins get lost, edges get sanded off, become folk wisdom
