Have started logging calories again, because it's the only thing that works. I'm also eating a somewhat larger breakfast (~500 calories instead of ~200), as I hear current wisdom is that front-loading helps you feel less hungry during the day. (Which is not a usual problem for me anyways; it's what I'm hungry for. MARS NEEDS PEANUT BUTTER. But it may prove useful.)
Going to aikido regularly makes the biggest difference of all, of course. And so far this week that's also proceeding well. But I need the better eating habits again, in general and for when aikido is not.
