As @baerdric said, if you're even doing a just the tiniest little bit to make yourself healthier, you're a hero.

We should all keep that in mind when we meet people who are doing things differently to ourselves. It doesn't mean they're doing it wrong because they're different to us, it doesn't mean we're doing it wrong because we're different to them.

here's room for all of the variations, and they've probably got a good reason for theirs.

Listen, learn, reevaluate.
