Today I was faced with an unknown menu (I wasn't in a position to ask about it), so I ate an egg-white omelet with cheese (2 points) and an apple (0 points).
It worked beautifully!
The menu turned out to be fairly safe (half wraps), but there were some food traps: potato chips and cookies.
I was able to make an informed decision whether or not to nosh on the chips and cookies (I didn't), but had I been starving, I probably would have indulged, which would have resulted in unplanned eating of junk food.
I ate one half wrap (most of the tortilla, all of the filling), but I was still a bit hungry, so I took another half wrap and just ate the meat (lean ham).
So, mostly, there are strategies for avoiding the numerous foods traps that our culture sets for us.
NOTE: I'm not saying that you should never eat goodies--never deprive yourself if you really want something yummy--but I hadn't planned for these foods and didn't want them.
I'm trying like crazy to get my book formatted and ready to take to Macedonia. But I forgot about the acknowledgments page and how much time it will take to get it ready. I may not make it.
