I am not sure where you read occasional fruit. The book simply states you shouldn't eat it alone and you shouldn't eat so much that it crowds other important items off your plate. Do you have a sugar dragon? I do, so I choose to rarely eat fruit. You don't have to eat any if you don't want to. Many consider one to two servings a day to be reasonable.
Welcome all newcomers, welcome back vets, and for those of you who never left...welcome to this post.
I just wanted to pop in here and remind you all to take a deep breath before you dive into all the questions about what you can and can't have. The program guidelines are clear on what you can and can't have (grains, dairy, W30 muffins), but things get a little grey when people start talking about what you should and shouldn't have. Please don't over think think this. You don't have to address every food related issue you have, break every bad habit, and shun every food that gives you comfort to succeed with your Whole30. If you need to you can always extend or repeat the process, and things will get better each time you do. My advice to you is this:
Stick to the rules like they are your port in a storm (really, they will become that).
Take the Moderators responses seriously (we know what we're talking about).
Take community members suggestions as advice from those who came before, but keep in mind they are not the rules and not the Mods. Everyone here is well-meaning, and everyone here wants to see you succeed, but everyone here is at a different place in this journey.
And finally, take comfort in these words (from Melissa Hartwig, on another forum post):
Here's the thing (and this is an interesting discussion)... there are Whole30 "rules," which are strict, clearly outlined, and very well defined. No grains - and here are all the things we consider grains. No dairy - and here are all the dairy items excluded. No Paleo-fied food choices, and here's what those look like.
Then, there are Whole30 suggestions for success. They're not part of the official rules, but they're things that we've seen really help (or harm) people as they move through the program. Fruit smoothies for breakfast - not a good idea. Skipping breakfast - not a good idea. Eating every two hours, all day - not a good idea. These things won't necessarily affect your Whole30 results (although they might), but if we can give you additional suggestions that will make your transition and your program easier and more effective, we're going to give them to you.
Keep Calm and Whole30 On.
