The average person will burn over 500 calories per hour carrying a pack while hiking the hills. A bar with only around 220 doesn't cut it.
I kind of settled on 5-6 bars a day, with overflow coming from a couple 3/4lb bags of jerkey and a ziplock of trail mix for lunch (everything between breakfast and dinner). 3 packets of instant oatmeal for breakfast, and a Mountain House for dinner. I still lost 14 lbs this year sheep hunting, but haven't found a way around that yet.
