I'm with you, anecdotes x 7 billion are stronger than bad science. Will I keep what I've learned? Yes! Is worry worse that bad pizza twice a year? Very yes.
Sounds like you've made the distinction between health vs. fitness. A good perspectuve to keep! I'm on board with that too, even though - and it's true - food did give me the abs I was always looking for. But that's just vanity, not health or fitness!
