I feel your pain on the Fall weight gain.
As you cycle thru the week (p1 day thru fun day) is the scale going up, down, or staying the same?
Would low-fat cottage cheese (about 1/2 cup) work for a late night snack for you? Or a small combo of cottage cheese & fruit or yoghurt and fruit? (about 1/2 cup of each)? Sometimes I do tend to need a little fat at night, but a tablespoon of peanutbutter both ends the cravings & often gives me a stomachache at night, so I'm thinking the cottage cheese would have a couple of grams of fat but not enough to be a problem.
What did your phase off look like after 3 weeks on p1? Did you spend 2 weeks on p2 and 2 weeks on p3? I'm not asking because I think that had anything to do with the gain, but more because I hate p2 and don't think another week of it is in the cards for me. (I'm hungry and need to separate out meals and snacks but I'm trying to do it "as written" and not in the mood for 100 calories every 2 hours.)
