In response to Mike's claim that 20 pounds is too much for 10 days of consumables, I'll play devil's advocate.
IF you adhere to the rigid UL philosophy of maximizing the caloric density of your foods, then he's right.
IF you are a weekender at casual levels of fitness and have a moderate amount of body fat, then he's right.
IF you have a low BF% (less than 10%) then you better up your caloric intake, which increases weight; or
IF you want to enjoy some foods with a low caloric density, then accept a little bit higher weight.
I love to take smoked salmon with me - a big old 4 oz steak a day for lunch is about right. Caloric density is 90 Cal/oz. This is a far cry from the 125 or 135 Cal/oz that you need to target to get away with MC!'s recommendation of 1.4 ppppd.
Other stuff I like to take: bell peppers (roasted over a fire!), nectarines, licorice, soup, coffee! None of these things have a high caloric density.
So I try to balance it out by taking nut butters, shortbread, ghee, Nido, dry sour cream, nuts, etc. for caloric boosts to my meals.
That said, 2 lb/day is not a big deal. That's about what I'll be carrying this week as I go into the Beartooths on a Wilderness Trekking School course.
I think one of the greatest benefits of reducing pack weight is to be able to add back weight in other areas to increase your enjoyment.
That's not to say I'm enjoying my food more than the guy who's bringing a diet of 135 Cal/oz, I'd rather have fresh nectarine juice dribbling down my chin than drool :D
