Oh and I would also deemphasize the importance of ketosis. People think some magical physiological shift happens when those sticks turn purple, but it just isn't true. The shift between burning primarily glucose and ketones is a gradient one, and having ketone bodies show up on a stick in concentration doesn't alone mean you are losing weight, eating/digesting less carbs, or doing atkins "better" than someone who's sticks read negative.

Also, a lot of people will think eating a food they shouldn't be eating is alright, so long as it "keeps them in ketosis". This is a bad way to think, because then they will believe they can eat any old junk regularly and have it be good for their bodies.

The importance of "ketosis" myth also gives people this crash diet mentality... they think so long as they have their ketosis safe zone, any transgression is remediable. It fosters an unhealthy mentality that this is a quick weight loss program, not a lifestyle change when in reality the only permanent weight loss is the fruit which is born of lifestyle changes.
