A couple things on the Zone

So I am sure that after Christina's talk you all went out and got Paleo food, figured out your blocks and ... Anyway, some of the things to think about when switching to this:

1. Any change sucks.  crossfit sucked at the beginning, and now?  Give it a try.  The easiest way is just figuring out the blocks for what you are eating.  Do that for a week, then try bringing what you eat in line with what your recommended blocks are.  This way, if you go over your recommended blocks, you won't be as hard on yourself.  It takes time getting the diet right.

2. Bars and drinks are good but do little to fill you up.  A 16 block diet would be 5 bars.  Try surviving on that crap for 14 hours.  Raw vegetables suck, and I came from being a vegetarian.  A happy medium.  The only way you'll get used to this is if you feel full.  Plus the bars have more sugar than we need.  There are lots of ways to get your blocks.  

3. Unless you have a really tight diet to begin with, or you are a glutton for punishment, don't start with Paleo.  It is way too limiting and very hard to do unless you are able to be around your house all day.  Try getting a Paleo meal when you are at work and forgot your lunch.

All in all, remember, you will feel better.
