Anyway, good luck with your experiment!
Regarding eternal counting, two things that may help:
Yoga and meditation have both made me much more aware of the experience of my body. Before I would eat long past the level that I now recognize as "full". Often because I just didn't notice. (Reading while eating made that especially easy.) Now I find it much more easy to keep stable.
The other trick is one from Carol Lay's graphic memoir The Big Skinny. She weighs herself every day. If she's within her goal range, she just eats without worrying. If she's above the limit, she goes back to counting. (Her system is simpler; she just tracks raw calorie numbers, not full food lists.)
I am planning to try yoga. The trick from Carol Lay sounds like a good one. Thanks for the ideas!
