I follow Ketogenic Diet (Fat Based). Should be much easier to maintain consistent diet when not at home.

I have a very healthy diet currently and will not be eating the standard crappy pasta / rice meals and definitely no Ramen noodles, TGHQ = Butane not going to eat my cooking fuel!

I will be dehydrating my veg's, Packing lots of Tuna Packs, Home made Pemmican, nuts, butter and coconut oil. I's much easier to get Fat Calories than Carb. calories!

Fat calories provide longer more sustained energy with no crash, High density calories.
