Summary

In this episode we tackle the science, myths, and dogma surrounding backpacking food and nutrition. Featuring guest Brian Rigby, certified sports nutritionist and author. We tackle food and nutrition issues as they relate to thru-hiking, ketogenic diets, plant-based diets (veganism and vegetarianism), gluten-free issues, and macronutrient-micronutrient nutrition. Some questions we ask: what are the caloric and nutritional needs of backpackers? Why do we need to address dogma and pseudo-science in this field? We also take a look at some new cooking and water treatment gear and discuss what’s going on in the world of Backpacking Light right now.

    I am not sure how many people do this. But, I often only eat once per day at home. Generally, I do not consider a snack of less than 100C a meal. I generally eat about 5 snacks per day. At supper, I load up with carbs, proteins and overall fatty foods. Often this is homemade pizza (pepperoni, cheese), fried peppers (olive oil), and other foods rich in fats. (Yeah, salmon is good, smoked steelhead, fried trout, too.) I think my calorie load is about 3/4 in the evening, 1/4 the rest of the day.

    I am type 2 diabetic. I avoid processed white bread, mac&cheese, wraps, and other foods that are >50% carbs. I generally cut my dose in half, or less when I am out on a longer trip. Though, I carry a couple cups of flour (whole wheat/bisquick 25%/75%) and cup of finely ground dried apples mixed in for apple fritters. Usually I substitute rice for carbs and bring a bag of a couple pounds of brown rice. Diabetes/blood glucose is not supercharged with rice like it can be with breads and other carbs. For those times when I get into low blood sugar, I carry some hard candy.

    I generally eat a high protein/high fat diet, with some carbs to get me moving through the day. And, yes, I use a vitamin/mineral supplement to insure scurvy, etc are avoided. Does it work? I can’t say, because I never feel that bad/lacking anything except water/salt over the course of any one day.

    On a through hike, or a two week outing, I have breakfast: oatmeal, 2 scoops of instant coffee, and a half packet of cocoa…Marco’s Mud. The type of coffee is not a high priority, but strong coffee is. Tasters Choice or Café Bustelo work fine, a double scoop works for me. I often have a second/third cup of mocha. (What the hey, sometimes four cups, but only the first has oatmeal.)

    Fritoes, potato chips, corn curls, etc make up my snacks during the day…usually about 1 small bag. Lots’a fats and calories.

    For supper, about 1/2 cup of rice, jerky, a tablespoon of pemmican, pepperoni, salami, sausage, etc, and dehydrated/cooked veggies. I eat about 2oz of jerky a day, often having some as a snack.

    Sometimes I will make a soup with one of the mixes from the market. A large variety is available but I am partial to minestrone, chili and lentils. I substitute dried beef, chicken, salmon, turkey, pork, (jerkys) for any ground meat. And add in some olive oil (I carry about 8oz on a two week hike.)

    This adds up to about 1.1-1.2pounds per day average. I plan on using my ample fat reserves for the difference. Generally, I have found you tend not to metabolize fat well if you eat during the day. Your body will use the easier route of for food. So, forcing this with small snacks and a more constant low level fat burn all day keeps me from bonking. I average something more than a half pound per day of fat loss, or around 5lb/wk. Being older also means less food requirements. I would estimate that my diet consists of about 30-35% protiens, 30-35% fats/oils, and around 35-40% carbs by the number of calories I eat.

    Andrew, have you tried Injinji toe socks? I used the liners for a while, not the hikers and have had absolutely no blisters. On the other hand, I am an old guy, wear light boots, and only do about 10 miles/d.

    On the gluten-free concerns:

    Coming from the Mom of a child with severe allergies, if a person on a trip has celiac or food allergies, it is up to THEM to do their food. It’s not a big issue frankly, and most people with those concerns will do better if left to them.

    Be wary of legume noodles if you are not sure of tolerance, so try them at home first :-)

    I know for us, he hates most GF pasta. He eats mostly meat, veggies, and fruit with other items for carbs when needed. Funny that my 6 year old eats better than most of us ;-) Hah!

    Very interesting, but also not surprising. My 16 year old said, with regard to the keto diet while backpacking and the vain hope of burning body fat for energy: “wandering around in the wilderness without enough food sounds really duuuuumb!” I guess that’s one takeaway.

    I’ve always taken a daily multi, and known that I’m probably peeing out most of it. But when I stop taking them I get moody and depressed, sort of PMS feeling, although that condition is no longer applicable. I’ve stopped and restarted the multi enough times in my life to believe that it is somehow connected with the mood issues, but have no proof to back it up. I eat a pretty darned healthy diet, so I shouldn’t need any extra vitamins. And yet… maybe all just in my head!

    Your podcasts are well researched and quite informative.  For me, this was the best one yet. Lots of great information.  Really looking forward to the webinar.

    Thanks for the podcast. It made my commute to work a bit more manageble ;-)

    On your blister problem:

    An old remedy to prevent blisters (at least in the Netherlands) is Camphor Spirit (a 10% solution of Camphor in (rubbing) alcohol) (The name over here is “kamferspiritus”).

    About a month before your trip start treating your feet daily by rubbing the alcohol/camphor solution on your feet, and letting it dry. This will cause the skin to harden slightly, The skin will become more resistant to blisters. Do NOT apply to broken skin.

    Before using please also read:

    @tundra-thrasher-ouch-man-2

    There’s a new nejm  review article on  intermittent fasting benefits and what different animal and etc trials concluded if folks are interested. I know it comes up a lot in backpacking light. This a good jumping off point to guide you to reputable studies https://www.nejm.org/doi/full/10.1056/NEJMra1905136?query=TOC
