Not too recently, I was walking around Military Commissary. I came across this great solution for backpacking, it is called Powered Peanut Butter, you add your own water. With the water missing the peanut butter will weigh less then regular peanut butter. The packaging also claims has 85% less fat then regular peanut butter. So I will try this peanut butter see how good it claims to be. Another good thing about this peanut butter it can be added directly to Pancakes to give more protein as well as a different taste. The possibilities are endless. I am not sure if you can get this product in the regular stores but if you come across it in the stores give it a try on you next Backpacking trip
