My buddy and I are both 220+ pound athletic guys, we moved about 12 miles a day between 2-4K vertical ft starting at 9.5k ASL. All we packed for food was Peak Refuel, some energy bars and instant coffee. We each had 3 packages a day which kept our calorie intake in line with our calorie output. Neither one of us had a bad meal, we were both very impressed with how filling each meal was, the flavor and the consistency/texture of the food. I will purchase this again for my next backpacking/hunting trip.
