It turned out that portion sizes were just about right for us; we needed to push ourselves to finish off the portions a couple of the nights, but we were never hungry after dinners. Lunches needed supplementation with nuts, etc., but we'd expected that and packed extras accordingly; breakfasts and dinners worked out great.
Our breakfasts were around 11 oz for 3 of us, or 3.6 oz per serving. Our dehydrated lunches were Laurie Ann March's Citrus Lentil (~4 oz per serving) and Indian Carrot (about 2 oz per serving) salads (other lunches were a few ounces of nuts/dried fruit/sesame sticks, plus a trail bar or cookies split 3 ways). Dinners were 4.5 oz per serving (generally 1.5 oz of starch with 3.0 oz of "stuff"), with the exception of spaghetti which was 4 oz plus 1 oz dried cottage cheese. We ended up having soup with dinner twice (1.5 - 2 oz per serving) and dessert every night (1.3 - 2 oz per serving).
So in terms of satiety, I felt full after each meal, and wasn't hungry until the next mealtime. BUT - I did feel more tired towards the end of the week, and am wondering if it was due to not getting sufficient calories, resulting in my body breaking down muscle? The meals were not particularly dense in calories, but pretty much the same nutrient balance as we eat at home - perhaps I need to include more fat in the backpacking meals to keep calories higher. The two guys did not have this complaint, so it may just be that the altitude and hiking eventually wore me out (also we were traveling faster by the end of the week, so maybe it just exceeded my capacity for speed). I *think* I lost some pounds on the trip, but too soon to tell; my weight hasn't yet stabilized since getting home Friday night.
I have to give big thanks to Laurie Ann for her wonderful recipes - I ordered both her cookbooks after returning from the trip, since the few recipes of hers I had gleaned from the web worked out so deliciously!
