Okay, so if you’re here, you’re likely curious about keto backpacking. Maybe you’ve already begun your keto journey. Whether you’re an experienced ketovore or just getting started, there are 3 key ways to eat keto smart while keto backpacking. Let’s first start with…

What is Keto Backpacking?

Keto backpacking means backpacking while following the keto diet. The keto diet (also known as the ketogenic or ketovore diet) consists of high-fat, low-carbohydrate meals, snacks, and beverages. This diet encourages your body to make ketones from fat. Ketones are then used as fuel. To be keto fueled, you generally shouldn’t eat more than 50 grams of carbohydrates daily. 75-90% of total daily calories come from fat.

Is Keto Backpacking Healthy?

Scientists still have a lot of research to do when it comes to the keto diet. But one thing is for sure: many backpackers are trying it out. Our focus here at Backcountry Foodie is to support keto backpackers in staying fueled as safely as possible. So, we will go over potential problems that you might run into on the keto diet and how to avoid them. After reading about of top 3 keto diet tips, be sure to check out our Keto Hiking Performance post.

Foods Included in the Keto Diet

  • Meats
  • Fatty fish
  • Poultry
  • Low-carb dairy
  • Low-carb veggies
  • Nuts, seeds
  • Avocado
  • Coconut products
  • Oils – olive, coconut, MCT, avocado
  • Butter

As you can see, the keto diet eliminates many foods from plant sources, such as fruit, grains, beans, and lentils, to name a few. Because of this, the diet is sometimes low in certain nutrients. Keep reading to learn more about potential vitamin and mineral deficiencies as a keto backpacker.

Now, let’s start with our keto backpacking deep dive and how to eat keto smart.


Keto Backpacking: Eating Keto Smart – Tip #1

Don’t Let Vitamin & Mineral Deficiencies Slow You Down

Ketogenic backpacking meals can be great for meeting your energy demands on the trail. However, in addition to eating adequate calories, keep in mind that your body also needs vitamins and minerals while backpacking. Due to the restrictive nature of the diet, keto foods can be high in fat-soluble vitamins (vitamins E, D, and K) but low in water-soluble ones (B vitamins and vitamin C). Not getting enough of these vitamins for an extended period can cause nutritional deficiencies, resulting in fatigue and an early end to your trek. If you’re following a ketovore diet for a long time (for example, a 5-month thru-hike), you might find our post 5 possible nutrient deficiencies when backpacking to be an eye-opening read.

Did you know that up to 50% of vitamins are lost in the food dehydration process?

Many keto backpackers rely on dehydrated meals while in the backcountry. Unfortunately, the process of dehydrating food can decrease its nutritional content. This is due to the extended heat exposure food undergoes during the dehydration process. Also, blanching before dehydration causes losses in the B-complex vitamins and vitamin C. Up to 50% of these vitamins can be lost in typical dehydrated foods. Remember that ketogenic diet foods are typically low in water-soluble vitamins anyway. Therefore, dehydrated keto backpacking meals have even fewer of these important nutrients than traditional backpacking meals. Ketovore backpackers should be aware of the following signs of vitamin deficiencies.

Thiamin/ Thiamine/ B1 Deficiency

  • Loss of appetite
  • Irritability 
  • Short-term memory problems 
  • Chest pain
  • Swelling of the extremities
  • Loss of feeling in the hands and feet 
  • Double vision
  • Memory loss
  • Confusion
  • Vertigo

Backpacking Foods High in Thiamine

  • Instant brown rice
  • Sunflower seeds
  • Beef (freeze-dried, dehydrated)
  • Yogurt (freeze-dried)
  • Oatmeal
  • Corn (freeze-dried, dehydrated)

How to Avoid Vitamin and Mineral Deficiencies while Keto Backpacking

Because ketogenic backpacking meals can be low in vitamins and minerals, consider taking a complete multivitamin and mineral supplement if you want to go keto for an extended period. In fact, whether you are backpacking or not, a multivitamin with 100% of most vitamins and minerals is a good safety net for just about anyone on a restrictive diet. (We recognize that being keto-fueled means you are eating this way as a lifestyle and not as a weekend warrior. Research shows it takes a minimum of 5 days and a maximum of 4 weeks to get your body to adapt to using fat as fuel1 ).

Don’t Let Dehydration Slow You Down

Many ketogenic backpacking guides seem to ignore the importance of hydration while in the backcountry. You may think, “I carry a hydration bladder with me on all my hikes; I’m definitely hydrated enough.” We want to share with you 3 reasons keto backpackers might be hitting the trail at a higher risk of dehydration.

1. Poor Water Absorption

Carbohydrates help your body absorb both water and sodium. Because the keto diet cuts out carbs, your body’s water absorption decreases substantially. This can be problematic for ketovores during physical activity when sweating increases sodium and water loss.

2. Frequent Urination

We’ve all been there. We’re out and about, on the trail, or just in our day-to-day lives, and it seems like our trips to find a restroom or off-trail location to relieve our bladder are never-ending. This could be even more likely on keto since the high amounts of ketones from fat breakdown are hard for our kidneys to process. Ketones are what get used for fuel. Our kidneys filter out waste and help our bodies maintain pH balance. This keeps us feeling nice and healthy. However, ketones are acidic, and this causes our kidneys to trigger more frequent urination to clear out the acid. If you don’t drink enough fluids to replace water lost from increased urination, you could become dehydrated.

3. Metabolic Acidosis

As mentioned above, using fat for fuel can be hard on your kidneys because acid is generated. The high acid production can actually overwhelm the kidneys’ ability to filter out the acid. When this happens, a condition known as metabolic acidosis may occur. This can be a serious issue and causes vomiting, lightheadedness, and fatigue.

Signs and Symptoms of Metabolic Acidosis

  • Rapid breathing
  • Fatigue
  • Confusion
  • Loss of appetite
  • Vomiting

Tips for Staying Hydrated as a Keto Backpacker

To keep your body hydrated, you’ll want to drink enough fluids and ensure you have electrolytes with those fluids. Sodium is the most important electrolyte to replace. It helps your body absorb and retain water. Other important electrolytes are potassium, chloride, calcium, and magnesium. You can get electrolytes by adding a supplement to your water or by eating electrolyte-rich snacks throughout the day. See What to Eat and Drink While Hiking in Hot Weather for more hydration tips.

Keto-Friendly Electrolyte Drinks:
  • Gatorade Zero
  • LMNT Recharge
  • Water with table salt
  • Pedialyte Zero Sugar

Keto Backpacking: Eating Keto Smart – Tip #3

Don’t Forget the Fiber

The keto diet tends to be low in plant foods. What comes along with plant foods? Fiber! Fiber keeps your gut healthy and maintains normal bowel function. That’s why cutting out plant foods like whole grains and fruits can cause constipation and other bowel issues. This can be disastrous on the trail. If you plan to be on the keto diet long-term, be sure to include sources of fiber. Nuts and seeds are great ways to add fiber to your diet. Just pay attention to the amounts, as many contain up to 8-10 grams of carbohydrates per ounce. Non-starchy veggies like dehydrated kale are also essential to include. Finally, you may want to consider a fiber supplement to fill the gaps.

  • I came across a ketovore book while at Shaw’s Hostel in Monson, ME this summer. It’s self-published and therefore may be harder to locate a copy, but here’s the info: Ausinheiler, Bryan. “Ketogenic Backpacking: How to Pack Lighter and Go Farther by Fueling with Fat.” (2018). Contains some of the theory and lots of recipes.
