Jeez, just noticed you obviously already read it. Here's what you can have:
1. Meat. Pretty much any type, but I suggest more dense meats like beef or lamb because they take longer to digest and contain more fat than fish or something. Eggs are great too. Try to only eat organic, if possible.
2. Nuts. Another good thing, try to eat only brazil nuts, pecans, walnuts and almonds, raw is preferable.
3. Vegetables. Be careful, because some are dangerous for you at the beginning, such as potatoes and carrots. Stick with leafy greens and squash, or green beans and such. Eat a lot.
4. Fruit. Berries are the best kind to eat, because they're compact and you can test your tolerance to different amounts of them. You may be able to eat apples or oranges as well, just make sure to never eat fruit on an empty stomach.
5. Fat. Lots of fat is good, better than increasing protein if you are eating low carbohydrates. Olive oil is the best way to get this, but you can easily get it in the nuts or fatty meats. Don't listen to what anyone tells you, fat is good for you, if you eat the right fat.
That's about it at the beginning. Let me know if you have any questions.
