Climbing Mount Kilimanjaro is a physically demanding experience that challenges both your endurance and strength. Many trekkers wonder if they will lose weight during the climb due to the physical exertion, high altitude, and long days of hiking. The answer depends on various factors, including your fitness level, diet, and how your body responds to the mountain’s conditions. This guide explores how much weight you might lose, the calories burned on the trek, and how to stay healthy while climbing Kilimanjaro.
Plan your Kilimanjaro climb with expert advice.
1. How Much Weight Do You Lose Climbing Kilimanjaro?
Most climbers experience some weight loss while trekking Kilimanjaro due to the high physical demands of the hike. The combination of intense hiking, reduced calorie intake, and the effects of altitude can contribute to weight loss.
Factors That Influence Weight Loss:
- Calorie Burn: On average, you can burn between 2,000 and 4,000 calories per day depending on the intensity of the trek and your body weight.
- Appetite Changes: Altitude can suppress appetite, leading to reduced food intake.
- Water Loss: Dehydration can lead to temporary weight loss, though this is quickly regained after rehydrating.
On average, climbers can lose between 4 and 10 pounds over the course of the trek, but this varies widely depending on individual metabolism and activity levels.

2. Calorie Burn on Kilimanjaro: What to Expect
Trekking up Kilimanjaro requires a significant amount of energy, and your body will burn more calories at higher altitudes due to the increased physical exertion and thinner air. The exact number of calories burned depends on factors like your weight, the route you take, and your pace.
Daily Calorie Burn Estimates:
- Moderate Trekking (e.g., Marangu Route): 2,000-3,000 calories per day.
- Challenging Trekking (e.g., Machame or Lemosho Routes): 3,500-4,000 calories per day.
- Summit Night (Uhuru Peak): Up to 5,000 calories due to the intense final push to the summit.

3. Effects of Altitude on Weight Loss and Appetite
One of the most noticeable changes at higher altitudes is a reduction in appetite. The thinner air and altitude can cause altitude sickness in some climbers, which can lead to nausea, headaches, and loss of appetite. Even without altitude sickness, many people find they eat less than usual during the climb, leading to a calorie deficit.
Altitude Effects on the Body:
- Appetite Suppression: You may feel less hungry at higher elevations.
- Increased Calorie Needs: Despite the reduced appetite, your body requires more calories to fuel your climb.
- Hydration Is Key: Dehydration can also suppress appetite, so it’s important to stay hydrated.

4. Staying Healthy: Balancing Nutrition on Kilimanjaro
While some weight loss is expected on Kilimanjaro, it’s important to focus on maintaining your energy levels and staying healthy throughout the climb. You’ll need to eat regularly to fuel your body, even if your appetite decreases.
What to Eat on the Trek:
- High-Calorie Foods: Choose foods high in carbohydrates and proteins to provide sustained energy. Nuts, energy bars, and dried fruits are excellent choices for snacks.
- Small, Frequent Meals: Eat smaller meals more frequently to help manage appetite loss and maintain energy.
- Stay Hydrated: Drinking water is crucial to prevent dehydration, which can further suppress appetite.
