I am almost 50 and been on the carnivore diet for about two years. I spend over 30 days in the backcountry every year hunting, hiking and scouting. In the off season I run 40-60 miles a week, do strength training and hit trails with my bike on 50+ mile rides. Never felt better in my life, but it did take some figuring out.
For backcountry trips I plan out each days food to include protein and fat but I pay no attention to calories or macro numbers. For context I am 5’10” and 210lbs. I have found that I eat very little when I am on these trips. Last September my son and I spent 16 days out on a grueling back country mule deer hunt. We packed enough food for the whole trip along with our gear in EXO 5000 packs.
What we bring is as follows.
For fluids - LMNT electrolyte packs, MTN Ops collagen packs, Lono Life bone broth, Paleovalley unflavored bone broth and Black Rifle instant coffee packs.
For fat - butter powder, freeze dried cheese
For protein - Freeze dried sausage, burger, beef chunks and eggs.
For snacks - Chomps beef sticks, homemade salted jerky (our Costco sells thin sliced New York steak we salt and dehydrate) and the freeze dried cheese.
For the hike in we make sure we hydrate well and eat a good meal before heading in. Depending on exertion we snack every hour even if we aren’t hungry. You have to stay ahead of the curve when your body is only processing fat. Every couple hours we dump a collagen pack and or unflavored beef broth in a water bottle along with an electrolyte pack. The collagen and broth adds protein and is tasteless. Once we are in we make our dinners and breakfast out of the freeze dried meats and eggs. We will dump a packet of bone broth and a packet of collagen in each meal along with a butter packet. This regimen has worked amazing for us, we feel great and have tons of energy. I drink coffee and when I make my morning cup I also add the collagen and broth to that.
For the freeze dried cheese, meats, unflavored bone broth and butter we order bulk cans and then vacuum seal single serving size portions. Doesn’t take a lot to keep you full and it weighs very little. Also takes very little space in your pack. I will add some pics of the stuff we use.
