Can you rely solely on energy bars for hydration and nutrition while hiking?
April 5, 2026
Quick Answer
No, relying solely on energy bars for hydration and nutrition while hiking is not recommended due to their limited nutrient profile and potential for gastrointestinal issues.
Limited Nutrient Profile
Energy bars are often low in essential nutrients like fiber, vitamins, and minerals. A single serving of an energy bar typically ranges from 200-300 calories, far short of the 2,000-2,500 calories needed per day for a moderate to high intensity activity like hiking. To meet nutritional needs, consider adding whole foods like nuts, dried fruits, and jerky to your energy bar.
Gastrointestinal Issues
Consuming high amounts of energy bars can lead to gastrointestinal issues like diarrhea, constipation, and stomach cramps due to their high sugar and salt content. This can be devastating in a backcountry setting where access to medical care is limited. A general rule of thumb is to limit energy bars to 20-25% of daily calories and prioritize whole, nutrient-dense foods.
Alternative Strategies
To stay hydrated and nourished while hiking, aim to drink at least 2-3 liters of water per day and consume a variety of whole foods including fruits, vegetables, whole grains, lean proteins, and healthy fats. Consider packing a portable stove or camping stove to prepare hot meals, and don’t forget to bring a water filter or purification tablets to ensure access to safe drinking water.
