Skiing is a legitimate calorie-burning workout, with downhill skiing burning roughly 350 to 520 calories per hour depending on your weight and intensity. Cross-country skiing pushes that number even higher, closer to 900 calories per hour. Whether skiing translates into actual weight loss depends on how often you ski, how hard you push, and what you eat when you come off the mountain.
How Many Calories Skiing Actually Burns
A 155-pound person skiing downhill at a light effort burns about 352 calories per hour. At moderate effort, that climbs to 422 calories. Vigorous skiing or racing pushes it to 563 calories per hour. If you weigh closer to 190 pounds, those numbers jump to 431, 518, and 690 calories respectively. These figures put downhill skiing roughly on par with moderate cycling or a brisk swim.
Cross-country skiing is a different animal entirely. It burns around 900 calories per hour and registers at 12 METs (a standard measure of exercise intensity), compared to 8 METs for downhill skiing. That makes cross-country skiing one of the most energy-demanding activities you can do, rivaling running at a fast pace. The difference comes down to propulsion: on cross-country skis, you’re powering every inch of forward movement with your own body, while downhill skiing lets gravity do much of that work.
One important caveat with downhill skiing: your actual skiing time is less than you think. A full day on the mountain includes lift rides, waiting in line, and breaks. If you’re on the slopes for six hours, you may only be actively skiing for two or three. That still adds up to a meaningful burn, but it’s worth being realistic about the math.
The Cold Weather Bonus
Skiing in cold temperatures gives your metabolism a nudge beyond what the exercise alone provides. A meta-analysis published in Frontiers in Physiology found that cold exposure increases daily energy expenditure by about 188 calories compared to being at room temperature. Your body activates specialized fat tissue (brown fat) to generate heat, and this process burns through stored fatty acids. In healthy adults with active brown fat, resting metabolic rate increased by 14% after cold exposure.
This doesn’t mean shivering on a chairlift is a weight-loss strategy on its own. But the combination of physical exertion and cold air means your body is working harder than it would doing the same exercise in a gym at 72°F. It’s a modest bonus, not a game-changer, but it’s real and measurable.
What Skiing Does to Your Muscles
Alpine skiing is heavily leg-dominant, relying on your quadriceps, hamstrings, glutes, and calves through sustained, forceful contractions. What makes skiing unusual is that much of the muscle work is eccentric, meaning your muscles are lengthening under load as you absorb the forces of each turn. Elite skiers show significantly increased knee extensor strength, and competitive runs can push oxygen uptake to 75 to 100% of maximum aerobic capacity in giant slalom.
Skiing also depletes muscle glycogen stores substantially. After a full day of intense skiing, glycogen (your muscles’ stored fuel) can be nearly emptied. Your body then needs to replenish those stores during recovery, which costs additional energy. The anaerobic demands are high enough that more than half of the total energy during a ski run comes from anaerobic metabolism, which is why your thighs burn on a long mogul field.
Building and maintaining leg muscle through regular skiing supports your resting metabolic rate. Muscle tissue burns more calories at rest than fat tissue, so the strength component of skiing contributes to weight management beyond just the calories you burn on the slope.
Downhill vs. Cross-Country for Fat Loss
If your primary goal is weight loss, cross-country skiing has a clear edge. Research comparing alpine skiing, cross-country skiing, and indoor cycling found that alpine skiing produced lower post-exercise calorie burn (about 33 calories in the 10 minutes after high-intensity effort) compared to cross-country skiing (44 calories) and cycling (45 calories). This afterburn effect reflects how hard your cardiovascular system was working during the session.
The reason is straightforward: cross-country skiing demands continuous, full-body effort. You’re using your arms, core, and legs simultaneously with no built-in rest periods. Downhill skiing, while intense during runs, involves natural recovery windows on the lift and between turns. That intermittent pattern keeps heart rate and overall physiological loading lower across a session.
That said, downhill skiing has one advantage cross-country doesn’t: most people find it more fun. Enjoyment matters for consistency, and any exercise you’ll do regularly beats one you avoid. Fat is the dominant fuel source at low to moderate intensity (around 50 to 60% of your maximum effort), which describes recreational downhill skiing well. At higher intensities, your body shifts toward burning carbohydrates. So relaxed, steady skiing may actually burn a higher percentage of fat per calorie, even though cross-country burns more total calories.
The Après-Ski Problem
The biggest threat to skiing as a weight-loss strategy isn’t the exercise itself. It’s what happens after. A day of cold, physically demanding skiing leaves most people ravenous, and ski resort food tends to be calorie-dense. A serving of raclette runs about 800 calories. A bowl of ramen at the lodge is 536. Even a relatively modest plate of fondue is 492 calories per serving. Add a couple of beers and you can easily erase half a day’s calorie deficit in one sitting.
This isn’t unique to skiing. Any vigorous exercise can trigger compensatory eating. But the ski culture of heavy, warming meals and celebratory drinks creates a specific trap. If you’re skiing for weight loss, paying attention to your post-ski meals matters as much as the skiing itself. You don’t need to eat like a monk, but choosing a polenta dish (205 calories) over raclette saves you nearly 600 calories, which is roughly what you burned in an hour of moderate skiing.
How to Get the Most Out of Skiing for Weight Loss
Skiing works best for weight loss when you treat it as a genuine workout rather than a leisurely vacation activity. That means minimizing time standing around and maximizing runs. Skiing harder terrain, taking fewer breaks, and choosing steeper or more technical lines all increase the calorie burn. If you have access to both, mixing in cross-country sessions on some days will dramatically increase your total energy expenditure for the trip.
For people who ski regularly throughout winter (weekends or multiple days per week), the cumulative effect is significant. Burning an extra 1,000 to 2,000 calories on a ski day, even accounting for increased appetite, creates a meaningful weekly calorie deficit over several months. Pair that with the strength-building effects on your legs and the metabolic boost from cold exposure, and skiing becomes a genuinely effective part of a weight-loss plan.
The people who struggle to lose weight while skiing are typically those who ski a handful of vacation days per year and treat each one as a food-and-drink celebration. That’s a perfectly fine way to enjoy a ski trip, but it won’t move the scale. Frequency and dietary awareness are what separate skiing-as-exercise from skiing-as-vacation.
