> I’ve been fascinated by the fact that I know several people who have become vegan, lost weight, and feel better. But I also know many people who have gone low carb, or even eat nothing but meat, and are also losing weight and report feeling much better. I have had a similar experience, but I've also known several people who have tried various diets and quickly dropped off them because it wasn't working for them. So while it's true that if you ask all your vegan friends if they enjoy being vegan, they'll probably mostly say yes, there's a huge possibility for selection bias/survivor bias. The lesson I've drawn is not "pick a restrictive diet and you'll feel better", but more "some things work for some people but not others, and we have no idea why". :-/
