Problem is, many fats go rancid. Not an issue for an overnighter but can be a deal breaker on a multiweek trip. Thus, margarine, which is stabilized. Butter, sadly, melts if not refrigerated.

Of course modern consciousness of health dangers of trans fats makes the whole issue more complex.
Olive oil (or other seed oils) is your best bet if you are trying to pack calories with minimum weight. It doesn't go rancid like animal fat, it also contains more calories(9 x gram) than butter (7 x gram), it's non saturated, if it's good quality EVO it also has vitamins. It's been a staple in my backpacking diet since day 1. Well it's been a staple in my everyday diet since day one since I'm italian...
