Some lovely folks on Mumsnet (*waves*!) have been asking about Paleo and recipe books. Now, to Joe (my personal trainer buddy and Paleo smartypants), this is all going to be way oversimplified, but the premise is this: You eat what the Paleolithic man ate.
Paleo man hadn't yet learned to farm, so the following stuff is a no-no
Anything with grain (bread, pasta, etc)
Potatoes (every once in awhile, you can have sweet potatoes, but no white/jacket potatoes!)
Dairy (sorry, no milk in your tea)
Anything in a box (cereal, oatmeal, macaroni and cheese, etc)
Essentially you are getting all your good complex carbs from the fruit and veg, and cutting out most of the simple carbs that usually go straight to your body as fat. I know it sounds really restrictive, but it's not. For example, I just had a huge rocket salad with 2 hard boiled eggs and diced onions/cucumber, topped with a quick dressing I made from the bacon fat and a little coconut milk, rendered down. Name another diet that uses BACON FAT DRESSING as a good food? ;) Also, your shopping is really easy, as you only go to the produce and meat section, which are usually right in the front of the store. Aaaaaaand, you can do it on the cheap! I got a bag of rocket for £1 at the Co-op, 2 eggs are about 50p (I like free range), about 50 worth of bacon, and maybe 50p worth of chopped veggies. I bet whatever crap you may be eating from the vending machine cost you that much!
Now, I am doing a modified Paleo, as you can have my coffee when you pry it from my cold dead hands, but other than the first few days of sugar/simple carb withdrawal, it's actually pretty nice. AAAAAAAAAAAND, you get bacon. And as mentioned above, bacon is just awesome.
As for a recipe book, the one he recommended to me that I really dig is Everyday Paleo. The lady who wrote it is a mum who needed to make food her kids would like, as well as being quick/pre-planned (so you don't have to spend hours over a stove just to make a sad little piece of boiled salmon). The instructions are super simple, and she has a great index of what foods are in and out. Easy peasy.
I hope this gave you a great into to the Paleo diet. As for exercise, I am doing lots of walking with baby (already did my mile today!), and will be starting back up on the Wii this weekend.
