At first I used FitDay, but it's turned to be a little tedious for me -- almost every food there (such as brands, etc) is geared to the US market, and it was annoying when I had to look up for French brands all over the place to finally have to enter them manually anyway.
For the moment, I use a simple notebook, in which I track down (approximatively) what I eat at which meal. I include calories when I can, and if I can't, I do my best to question myself about my food choices, whether they were good, average, bad, really bad, etc (as well as whether I went overboard with the quantities). At first, I was afraid that I *would* go overboard and totally delude myself regarding that, but it seems that getting into thinking mode helps (that, and using small plates and bowls anyway
). If I need to become more stringent about that, I'll do it. For the moment, I know that if I want to do too much, too perfectly, too soon, I'll just fail, so I'm... working through trial and error until I'm used to it and can start devoting new resources to it again (if that makes sense).
