I find it very helpful to create an Ana notebook or journal. How do you do that? Well, I'll tell you that.
So, get a notebook. What I find works best is a fairy thick spiral bound notebook. Don't decorate the front or write "Ana Notebook" on the front; leave the cover blank. Try to get a notebook in a neutral color. It shouldn't be bright or neon because then somebody could pick it up and be like, "Oh this looks interesting." I also suggest against black or dark purple. Those are just naturally mysterious colors that scream, "Read me!"
There are many different ways to do this, but I strongly suggest putting a calorie table in the back of your notebook. Either sort the foods alphabetically or by type (ex: fruits, cakes, vegetables, cany, meat, ect). On each page, have a 'food' column, a 'quantity' column, and a 'calories' column. Example:
Food Quantity Calories
Apple 1 medium 80
Carrots 1 oz. 12
Put the date somewhere on each page... And it's pretty much up to you what you do with the rest. Write Ana tips and tricks, print out pictures of thinspiration and glue or tape them into your notebook... Anything. But, there's one more thing that you absolutely HAVE to do.
Keep a daily food log, to keep track of your calories for that day. Mine for today might look like this:
Late July Natural Cheese Crackers, 1 pack (130)
+ Subway sandwich, 1 quarter (250)
+ Banana, 1 whole (101)
481 calories, 3-18-13
