"Everything in moderation" isn't actually great diet advice. There's a paper floating around somewhere showing that people with a limited diet of healthy things fare better than people with a very wide diet that included unhealthy things.

My take is that "everything in moderation" is a mental crutch that people adopt when there's some part of their diet that they know isn't _good_ but that they don't want to give up completely. It is true that we can sneak in unhealthy food here and there without hugely detrimental effects, but that doesn't mean it's a good baseline practice.

The one scenario where it might be useful advice is with somebody whose diet is terrible, and you want to ease them towards a somewhat nutritionally positive diet; even in this circumstance, a more direct approach of "eat less crap and more good stuff" would be more accurate.

Most people aren't going to stick to healthy foods only though, thus moderation is "good enough", It's better to be at 75-80% and not feel guilty rather than 10% good food and 90% junk food because you just couldn't do the 100% good all the time diet
