If I'm thru hiking, how can I increase the calories?

Most hikers and outdoor adventurers will be just fine with 600‑700 calories per meal, but thru-hikers need a bit more to feed the #hikerhunger. As our caloric needs ramped up around mile 300 on the PCT, we started adding extra calories to our meals by way of olive oil and butter powder. Pro‑tip from the trail: the plastic bottles of baby oil you find in the travel section of your local drug store are GREAT for carrying olive oil in your bag without leaks.
