Hi Matt, yes indeed it could also be due to survivorship bias, or a combination of survivorship and the suggestions I made.
Not based on anything empirical but I imagine that health related reasons are probably especially vulnerable to drop out because potentially all it takes is finding some other diet that promises health benefits and the person might make a switch.
