Healthy Lightweight Eating for Hikers: How to Reduce Pack Weight & Have More Energy

hikers

Carry a lighter pack, eliminate bonking, free yourself from cravings and reduce hiker hunger…. sound good? Well, it’s possible, and it starts with what you’re putting in your food bag. Here’s how I approach eating a healthy lightweight diet on trail.

This post will explain why a healthy high fat diet is optimal for backpacking and how to start developing metabolic efficiency.

Personal Backpacking Nutrition Evolution

Over the course of 8000+ miles of backpacking, my nutrition strategy has evolved. Going into the AT in 2009, I had no idea how to eat for backpacking, so I started Googling. Pop-tarts, ramen, and snickers? As a lover of veggies (and feeling good), I knew that approach wasn’t going to work for me. I pieced together as healthy of a diet as I could, but it was still fairly processed and I never really felt great on it.

As a cold-soaking vegetarian on the PCT in 2014, I did a bit better. I’d learned a thing or two, both about health and how to carry that onto the trail. I focused a lot on legumes (dehydrated black beans, refried beans, and hummus), nut butters, tortillas, dried fruit, seeds, nuts, and with a handful of dried kale in my dinners. I felt better than on the AT, but by the end of the trail, my digestive system was…um, ‘off’, to put it nicely. Plus, I had a deep fatigue that had built up by the end of the hike and, it turns out, I was anemic.

So, in prepping for the CDT, I continued to make changes. I no longer eat much of the food that wrecked my gut in the past, such as gluten, industrial seed oils, grains, or even as many legumes. I’ve also learned that I feel best when I eat a high fat, lower carbohydrate diet, rather than the traditional ‘endurance diet’ heavy in carbs.

Fortunately, that high fat diet works well for backpacking. More on that in a moment. But it’s important to note that ‘high fat’ can be done in an unhealthy way or in a healthy way. It just takes a bit more knowledge and care to do it right within the constraints inherent to backpacking.

Being part of various endurance communities, I’ve been fascinated to witness hikers loading as much sugar as they can fit into their food bags, thinking it’s the only way to have lots of energy. Of course, it’s the traditional carb-loading approach, and it’s not uncommon to hear nutrition professionals preaching it too. “Calories and carbs are all that matter. It’s not important where they come from.” (You can read here why I think that’s a terrible idea if you want to eat for optimal performance and health.)

I’ve see distance runners struggle with digestive issues as they refuel on sugary gels every 90 minutes. I’ve seen (and experienced) the bonking. And on this standard high carb, high sugar, highly processed diet, I’ve watched hikers suffer with weaker immune systems, experience insatiable hunger, carry heavier packs than necessary, and even have teeth rot from excess sugar.

And that’s just what I’ve witnessed on trail, let alone, what happens to their mental and physical health once they return home.


There’s a Better Way

That said, the focus of this article is to share why my fueling strategy has evolved to what I call Healthy High Fat. I’ll also cover how to execute that in an easy, effective, and efficient way.

Let’s state up front that what I’m NOT talking about is a zero carb diet and going into nutritional ketosis. There’s a time and place for ketosis as a therapeutic approach, but in general, we need all the macronutrients (proteins, fats, carbohydrates) to stay healthy and to perform at our best.

What I am suggesting is that there are many benefits to be had by using fat as your primary fuel source on a backpacking trip.

The Benefits

‘Why bother’, you may be thinking, ‘I like candy bars, bagels, and pasta’. I get it. I like carbs too (hi, my trail name is Salty because I eat all.the.chips.), but I like sustained energy and carrying a lighter pack even more.

Favoring a higher fat/low to moderate carb diet and training your body to burn fat preferentially makes sense for backpackers for the following reasons:

Lighter Pack

*At 9 calories per gram for fat and 4 calories per gram for protein or carbs, fats are more than twice as energy dense per unit of weight than protein or carbs. We need a certain amount of protein each day to prevent muscle wasting and facilitate muscle repair. The remainder of your energy is made up of either fats or carbs, as these two macronutrients are the primary sources of muscular energy. Because fat is more calorically dense, you can carry the same amount of calories for less food weight than you can if you were carrying predominantly carbs.

Sustained Energy (less bonking!)

*Favoring fat over carbs leads to more sustained energy. Here’s why: Consuming carbs causes blood glucose levels to spike which causes the pancreas to release insulin to shuttle glucose into cells, which then causes blood sugar to quickly drop, and you bonk, hit the wall, get cranky or tired, and crave another hit of sugar.

*Additionally, “The average person has approximately 1,400 – 2,000 calories worth of carbohydrate stored in their body and 50,000 – 80,000 calories stored as fat.”  By training our bodies to use fat more efficiently as a fuel source, we can go longer without bonking. More on that in a moment.

Less Extreme Hiker Hunger

*As described earlier, fat and protein are slower burning fuels than sugar. They are absorbed more slowly and do not cause the same roller-coaster spike and crash of sugar.

*While I do eat slightly more calories on a long hike than in my everyday (significantly more sedentary) life, I generally don’t experience the extreme hiker hunger which my companions describe. I believe the difference is that I eat mostly whole foods as opposed to ultra-processed, low fiber, high sugar foods.

*Studies have indicated a significant decrease in hunger on a high nutrient diet when compared with a low nutrient diet. In an attempt to make up for nutrient deficiencies, the body reaches for more and more food despite consuming sufficient calories. Many hikers report needing 5000-6000 calories per day. I generally feel good, experience sustained energy, and little weight loss at 3000-3500 calories per day, even on a thru-hike. Of course it depends on body size, but I believe a reason many hikers consume so much is because their food choices are low in nutrients and fiber.

Better Immunity

*Excessive sugar can set off an inflammatory cascade that suppresses the immune system. Your body is already under a great deal of physical stress on a long hike. Stressing it out more by forcing it to subsist on fare that is high in sugar and low in stress-fighting nutrients sets you up for issues. It’s not uncommon to see hikers catching colds and experiencing injury more often on trail possibly due to weakened immune systems.

Less Inflammation

*The reduction in systemic inflammation that can result from eating less processed foods, and focusing instead on balancing blood sugar, is the main driver of my interest in high fat/lower carb eating. Due to my history with autoimmune thyroid issues, reducing inflammation is critical, especially on trail.

Fat is Ideal for Low to Moderate Efforts

*Fat is an ideal fuel for low to moderate efforts, like hiking all day. When you train at a low intensity, you keep your heart rate lower, in the aerobic zone, where fat is used as the primary fuel. The more you train at low intensities, the more efficient your body becomes at converting fat to fuel. This article and this article explain this concept well, as does Mark Sisson’s Primal Endurance.

*On the other hand, all-out efforts (like sprints) are a more glycogen-dependent activity. This is where carbs can come in handy. It’s why I often eat a bit more carbs when I have a big climb ahead of me and need quick-burning fuel for my muscles. Essentially, I try to use carbs strategically.

Understanding Metabolic Efficiency

What this all comes down to is increasing metabolic efficiency (ME). ME refers to how efficiently the body uses its internal stores of fats and carbohydrates. The goal of ME training is to improve health and performance. This concept was established by Sports Dietician Bob Seehobar. Find the details here.

Through ME training, the body can be taught to favor burning fat over carbs. Increasing ME speaks to your ability to burn more fat versus carbs at the same intensity. As mentioned, the average person has approximately 1,400 – 2,000 calories worth of carbohydrate stored in their body and 50,000 – 80,000 calories stored as fat. Training your body to burn more fat spares it’s limited glycogen (carbohydrate) stores.

According to Seehobar’s website, the benefits of improved metabolic efficiency include 1) decreased body weight, 2) decreased body fat, 3) improved and sustained energy levels and mental alertness throughout the day, 4) improved recovery, 5) improved cognitive function, 6) improved power to weight ratio, 7) improved running velocity, and 8) better sleep.

ME can be tested through a machine that measures the oxygen you inhale and the carbon dioxide that you exhale while exercising on a treadmill or cycling ergometer. By plugging these numbers into an algorithm, one can determine the amount of carbs versus fat they burn at any given intensity.

Generally, as you increase the intensity you shift from burning more fat and less carbs to burning more carbs and less fat. For an example of what this looks like, check out this post by accomplished long distance backpacker and runner Andrew Skurka.

As mentioned, the high fat, low carb paradigm goes against traditional endurance nutrition practices, but is backed by solid science. Researchers supporting this approach include Dr. Jeff Volek and Dr. Stephen Phinney, Dr. Peter Attia, and Dr. Tim Noakes, among others. Furthermore, this nutrition strategy is being employed by endurance all-stars like Timothy Olson and Zach Bitter.

How to Improve Metabolic Efficiency

While there is a genetic component to how good of a ‘fat-burner’ you are, it’s something that’s highly trainable. According to Seehobar, “The majority of improving metabolic efficiency lies in daily nutrition changes and the ability to control and optimize blood sugar through eating proper amounts of protein, fat, and fiber, while accounting for the proper nutrition periodization to support athletes in different training cycles.”

Optimizing blood sugar, or glycemic variability, is something I talk about a lot. It refers to how much our blood sugar shifts throughout the day. According to health guru, endurance athlete, and personal trainer Ben Greenfield, “when it comes to your health, (glycemic variability) is, in my opinion, a more important variable to consider than cholesterol, vitamin D, minerals, telomere length, cortisol, testosterone or just about any biomarker one could ever measure (except, perhaps, inflammation, which I would rank right up there with glycemic variability).”

Reducing glycemic variability is critical to the overall picture of health, including reducing risk for metabolic syndrome, which predisposes you to stroke, cardiovascular disease, obesity, diabetes and other chronic health conditions.

As Seehobar states, the key to optimizing blood sugar is to include protein, fat, and fiber with everything you eat. Reducing the overall amount of carbs consumed is also essential, as when you limit incoming glucose, your body will rely on stored body fat for energy.

As mentioned, you don’t need to go extremely low in carbs to see benefits, and in fact, too little carbs can cause issues, such as hypothyroidism. Further, extreme restriction can lead to binge and purge cycles.

Managing Tendinitis Naturally

The Trail Show Salty Segment April 2019

The Question

Dear Salty,

What diet or supplements would you recommend to help combat tendinitis?  I’ve been suffering from Achilles tendinitis for a couple of months now.  I’ve been in PT for 5 weeks. It seems I may have turned the corner, but I’m wondering if you can give me some specific foods or supplements that can help me continue to heal.  I have friends who swear by collagen and bone broth, but I haven’t tried these things. Anything you suggest for on the trail or at home would be great.

Thanks, Lemuel

The Answer

Great question, Lemuel, as this is something a lot of hikers struggle with. As a health and nutrition coach, I don’t diagnose, prescribe, or treat, but I can share what I’ve seen work for myself and others when it comes to tendinitis. Here are some ideas for how you can support your body in recovering more quickly.

What is tendinitis?

For anyone unfamiliar, tendinitis (also called tendonitis) is an inflammatory condition of the tendons. The tendons connect muscles to bones. Tendinitis is often caused by repetitive movements, injuries, or built up inflammation. It can affect people of all ages, sizes, and physical ability, and it’s quite painful. Inflamed tendons are more prone to stress, strain, and tears. Traditionally, treatment involves rest, ice/heat packs, PT, and anti-inflammatory medications.

How To Combat Tendinitis with Diet & Supplements

Follow an Anti-inflammatory Diet

Because tendinitis is an inflammatory condition, the first thing to implement, if you’re not already doing so, is an anti-inflammatory diet. Food can have a dramatic effect on inflammation levels, with some foods combating inflammation and others feeding the fire. This is something I talk about a lot with your trail diet.

An anti-inflammatory diet is one that’s heavy in plants, especially cruciferous veggies (like broccoli, cabbage, cauliflower, and kale). This is because plants tend to be high in antioxidants. Antioxidants combat oxidative stress and free radical damage, which are the primary drivers of inflammation. Vitamin C is an antioxidant found in high quantities in berries, and it helps rebuild collagen, a key component in tissues.

It’s also important to eat high-quality proteins sourced from grass-fed, pastured animals. This helps the body repair and rebuild damaged tissue. Aim for 4-6 ounces with each meal. Examples include cage-free eggs, grass-fed beef, and wild-caught fish. Fish are also a great choice because they contain anti-inflammatory omega-3 fatty acids.

Also aim to include a wide variety of herbs and spices, which are potent sources of anti-inflammatory compounds. Ginger and turmeric are great options.

On the other hand, inflammatory foods to avoid include alcohol, excess caffeine, sugar, processed foods, and hydrogenated oils.

Supplementation

It’s best to get your nutrients from whole foods, but if you want to supplement, consider the following.

  • Zinc: supports the immune system and tissue repair
  • Curcumin (found in turmeric): very effective anti-inflammatory properties
  • Fish Oil: contains high amounts of anti-inflammatory omega-3 fatty acids
  • Magnesium: supports muscle recovery and restful sleep
  • Bone broth: contains collagen, which helps form tissue in the body

That’s my A to your Q, Lemuel. Hope you heal up quickly and get #backonthetrail.

Herb Crackers

Easy Herb Crackers

(gluten free, grain free, paleo, vegan, refined sugar free…nothing but the good stuff)

Unless you’re new here, you may know that I have a strong affinity for salty, crunchy snacks. I’m always on the look-out for convenient foods that will make my body function optimally, and of course, snacks should be tasty.

Hit with a crunchy craving recently, I went rummaging through my cupboard and nary was a salty snack to be found. Not feeling like going to the store, it was time to get creative, and thus these Herb Crackers were born. They’re gluten free, grain free, vegan, contain no refined sugar, and are made up of few simple ingredients. They’re also ridiculously simple and result in a house filled with savory scents while they bake.

I’ve had a couple bags of tapioca flour in my freezer that a friend gifted me while I was on the Autoimmune Paleo diet as part of a protocol to heal my adrenal fatigue and hashimoto’s thyroiditis. Prior to these crackers, I hadn’t baked with tapioca flour, so I’d put off using it for over a year. Today was the day.

I searched online to generate ideas and inspiration for the basic cracker process and to see if there was anything special to know about baking with tapioca flour. Tapioca flour is the starch extracted from the cassava root, while cassava flour is the whole root. Generally, tapioca is well-tolerated and avoids causing an immune response, as happens with many other grains. Plus, it’s fairly neutral and lends itself well to taking on any flavor you want. However, it’s still a starch and will therefore raise insulin, so eat in moderation and pair these crackers with a fat and a protein.

These crackers are quick and easy to make, even if you’re not an experienced baker and  have never worked with alternative flours. They only have a handful of ingredients, most of which you likely already have. The tapioca flour could be swapped out for other fours like cassava, almond, or coconut.

In addition to making your house smell glorious, and being able to tailor the herbs to your personal preferences, another benefit of homemade crackers is that you don’t get the myriad of preservatives, food coloring, and additives that are often found in commercial baked goods. That alone makes it worth the little bit of effort it takes to whip up these savory little crunchies.

Easy Herb Crackers (grain free, gluten free, vegan)

Prep Time: 10 minutes

Cook Time:  55-60 minutes

Ingredients:

  • 1½ cups tapioca flour
  • ½ cup coconut flour
  • ½ teaspoon Himalayan salt
  • ½ teaspoon garlic powder
  • ½ teaspoon ground fennel seed
  • ½ teaspoon celery seed
  • 2 teaspoon basil
  • 2 teaspoon oregano
  • 1 teaspoon tomato powder
  • ½ teaspoon baking powder
  • 6 tablespoons extra virgin olive oil
  • 8 tablespoons filtered water

Preparation:

Preheat oven to 300 degrees. Combine the dries in a mixing bowl. Feel free to use the combination of spices listed above, or create your own concoction. This is just what I had on hand. Add in olive oil and water. Combine thoroughly.

dough

Dough should be a somewhat sticky consistency, but it will stick together in a lump. It won’t be overly loose nor will it be so dry that it doesn’t stick together. You should be able to hold it without it falling through your fingers. Add more flour and/or liquid to adjust consistency as necessary.

crackers

Dump the dough onto a piece of parchment, flatten it into a rough rectangle with your hands, and place another piece of parchment over it. Smooth dough and press into an even 1/4″ rectangle(ish) with a rolling pin. Remove the top piece of parchment and pull the bottom piece onto a baking sheet.

crackers

Bake at 300 degrees for 30 minutes. Remove from oven and use a pizza wheel or knife to cut the dough into roughly 1 inch squares. Return squares to baking sheet with some space in between each. Bake another 25-30 minutes until golden brown and lightly crisp.

Cool completely and store in airtight containers. Enjoy with soup, nut butter, hummus, cheese or cured meat.
