By failing to change long-term habits, a dietary belief system can actually induce those episodes of recurrent dieting and recurrent belief dissemination. Diet schemes also differ in how often they induce inquiries from nonhosts. Each time adherents achieve dramatic weight loss, virtually all their regular acquaintances notice. The replication advantage here depends on how well the diet plans lead to drastic weight loss. But unless dieters go back to recurrent dieting, their acquaintances eventually stop marveling and inquiring.
New acquaintances replace old, and lasting acquaintances eventually forget about long-lost obesity.

So the diets depend on pathological aspects for their retransmission, and that keeps diet pathologies prevalent.
