Carbohydrates and protein eaten in the appropriate amounts are the foundation for good backpacking nutrition. Keep in mind that the goal for both of these nutrients is to meet your dietary needs. More is not better in this case, and I will explain why later in this post.
Backpacking Nutrition Tip #1:
Forget the low-carb diet.
Carbohydrate is your body’s preferred fuel source and an integral part of good backpacking nutrition. The trail is no place to skimp on carbs! You should always fuel up with a small amount of carbohydrates before a hike. Then, consume carbohydrate-containing foods throughout your day to sustain energy. If hiking for more than 2.5 hours, try to consume at least 60-90 g carbs (240-360 calories) per hour.
Which foods contain carbohydrates?
Fruits, vegetables, pasta, rice, crackers, chips, quinoa, cereal, and oatmeal are common hiker foods that contain carbohydrates. An easy way to remember this is that carbohydrate foods come from the earth. Those might seem obvious, but there are foods that you might not consider as sources of carbohydrates, such as milk, cheese, yogurt, non-dairy alternatives, and nuts.
Which foods do not contain carbohydrates?
That leaves pure animal products (without breading or sauces) and pure fat sources such as butter and oils.
How much carbohydrate is enough?
The recommended intake is 2 pieces of fresh fruit or 1 cup of dehydrated per day. This goal is typically easier to meet as dried fruit is included in various trail mixes and backpacking meals.
The recommended intake is 2 ½ cups of fresh vegetables per day or 1 ¼ cups of dehydrated per day. That’s a hard goal to meet at home, let alone while backpacking.
Now, here’s how backpackers can make up the carbs that aren’t consumed via fruit or vegetables. The recommended intake is 3-5 servings of whole grains daily. A hungry backpacker can easily meet or exceed this goal by including whole grains with each meal and possibly snacks. Whole grains not only fuel your muscles but reduce problems with constipation. This can be a real problem for long-distance hikers or folks on extended expeditions who consume low-fiber foods for weeks to months. Good backpacking nutrition can be achieved by consuming various dehydrated fruits, dehydrated vegetables, and whole grains.
Example 30 g carbohydrate serving sizes:
- 1 energy bar
- ½ cup dried fruit
- ½ cup couscous
- 1 cup oatmeal
Calculating carbohydrate needs
For hikes 1-3 hours in duration, which is considered an endurance activity, you’ll need 2.5-4.5 grams per pound (5-10 g/kg) of carbohydrate per day. Backpackers’ individual carbohydrate needs can be calculated using 8 grams of carbohydrate per 1 kg of body weight as an average.
To determine your daily carbohydrate needs:
- Divide your weight in pounds by 2.2 and multiply that number by 8.
For example, carbohydrate needs for a 150-pound adult:
- 150 lb /2.2 lb per kg = 68 kg x 8 g per kg = 545 grams of carbohydrate per day.
Are more carbs better?
Not if the source of carbs just sits in your stomach. Keep in mind that too much food taken in at once can slow the rate of digestion.
Backpacking Nutrition Tip #2:
The Goldilocks approach to protein.
Protein also plays an integral role in good backpacking nutrition. Protein is important for recovering from your hike and, when paired with carbohydrates, can prolong satiety. For most people, eating about 15-20 grams of protein at each meal and snack is plenty to meet your daily protein needs. Contrary to popular belief, exceeding protein needs does not enhance performance. In fact, it can be detrimental to performance because carrying extra protein will add unwanted weight to your pack. When thinking about protein, channel your inner Goldilocks to pack just the right amount.
Which foods contain protein?
Freeze-dried chicken and beef, tuna pouches, jerky, and textured vegetable protein (TVP). Those might seem obvious, but some foods are good sources of carbohydrates and protein, such as milk, cheese, yogurt, beans, nuts, and seeds.
How much is just right?
The recommendation for an average adult on a non-hiking day is 0.8 g of protein per kg of body weight per day. Backpackers, however, put a lot of stress on their bodies and require a greater protein intake.
Calculating protein needs
Individual protein needs for hikers and backpackers are calculated as 1.2-1.6 grams of protein per kg of body weight. This gives you a range for your protein goal. Protein needs can be higher or lower depending on factors like the length of your hike, elevation gain, terrain type, and the weight of your pack. The goal is to stay within this range.
To determine your daily protein needs:
- Divide your weight in pounds by 2.2, then multiply that number by 1.2 and 1.6.
Protein needs for a 150-pound adult:
- 150 lb / 2.2 lb per kg = 68 kg X 1.2 – 1.6 g/kg = 81-109 grams of protein per day.
Backpacking Nutrition Tip #3:
Protein and carbohydrates – better together.
Boosting your backpacking nutrition by consuming protein and carbohydrates together will help you prolong satiety and keep you going longer. This translates to less time eating and more time hiking. Each time you eat, aim to include around 30 grams of carbohydrates and 15 grams of protein at each meal or snack.
Examples of protein + carbohydrate pairing :
- 4 Tbsp nut butter + 1 cup oatmeal = 16 protein, 30 carbohydrate
- 1 oz beef jerky + ½ cup dried fruit = 15 g protein, 30 g carbohydrate
- 1 tuna pouch + 1.5 oz pita chips = 17 g protein, 28 g carbohydrate
Backpacking Nutrition Tip #4:
Don’t forget the fluids!
Another important consideration regarding backpacking nutrition on the trail is ensuring adequate fluid intake. Dehydration negatively impacts performance, and the signs of dehydration are rather unpleasant to experience. Learning your fluid needs will enable you to stay hydrated and energized throughout your hike.
Signs of dehydration:
- Reduced urine output
- Lack of energy
- Lack of appetite
- Rapid breathing
It is important to understand that thirst is not a good mechanism to tell you that you need to drink water. If you feel thirsty, you are already on your way to becoming dehydrated.
- Set a timer that will remind you to drink water periodically throughout your day.
- Fluid needs will vary from person to person, but everyone should begin a hike by drinking 8-16 ounces (230-470 mL) of water.
- After that, drink enough water to prevent losses of more than 2% of your body weight.
- If hiking for multiple days and weighing yourself is not an option, keep an eye out for signs of dehydration (see above).
- Climate and the type of sweater you are also influence fluid needs.
Are electrolytes necessary?
Electrolyte replacements are an unnecessary expense and add unwanted weight to your pack. Electrolytes can be sufficiently replaced with salty foods during and after your hike for most backpackers.
Backpacking Nutrition Tip #5:
Eat to hike, not hike to eat.
Improving your backpacking nutrition can require a lot of time and patience. However, the more time you spend on the trail, the more you will learn about how your body responds to food. From there, you will begin to identify what changes need to be made.
Stay curious throughout this experiment and use every hike as a learning opportunity. Once your nutrition is dialed in, you will hike faster and stronger without focusing so much on your food. This will improve your experience on the trail by removing unnecessary weight from your pack while meeting your nutrition needs with foods you enjoy.
