Journaling

In order to account what and when I eat, I keep a food journal.

I've been improving and adding information to my journal. I use a moleskine notebook (could be any notebook, but I like this one).

In its right page, I define a plan, normally made in the night before. This plan contains what (specifically - including calories and food weights) and when (hour) will I eat the next day. Additionally, I define the goals that must be accomplished that day, both nutritional and training goals.

In the left page, I write everything I indeed ate that day. I write in this page as well indications that I had a minimum of 1,5l of water, that I've trained and that I did not eat bread at meals.
