Calories Burned Hunting at 85 kg — 425 kcal per Hour
calories burned hunting 85kg — the short answer is 425 kcal per hour. That figure is for a 85 kg (187 lb) person hunting at the intensity the 2011 Compendium of Physical Activities assigns to it, and this page works the number out in full so you can check it, scale it to any session length, and see how it compares with other activities at the same body weight.
The headline number is an estimate, not a measurement of your body. Two people of the same weight doing the same activity for the same hour will burn different amounts, because fitness, technique, temperature, and how hard they actually push all move the real figure. What the formula gives you is a fair, standardised comparison — the same method researchers use when they rank activities by energy cost — and that is exactly what it is useful for: comparing options, planning a week, and setting a realistic expectation before you start.
Hunting is a walking activity with weight: covering rough ground, often uphill, carrying a rifle or bow, a pack and sometimes a heavy load back out. The Compendium rates general hunting at 5.0 METs, a moderate effort — the same as a brisk walk — but that average blends long still periods in a stand with hard walking and carrying. A day of still-hunting through hills costs considerably more than a morning sitting in a blind.
Work out your own number
Use the calorie calculator to get your own daily figure: it combines your basal metabolic rate with your activity level and your goal, so a single activity session slots into a full-day picture instead of floating on its own. If you want the activity alone at your exact weight rather than the 85 kg worked example on this page, the running calorie calculator takes any weight and duration and applies the same MET method. Both tools show their working, and both label their results as estimates.
The formula, shown and cited
The calculation comes from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8):1575–1581), which assigns every activity a MET value — a multiple of your resting metabolic rate. One MET is the energy you use sitting quietly. The formula is:
Calories per hour = MET × body weight (kg)
For this page the MET value for hunting is 5, which makes it a moderate-intensity activity by the usual classification (under 3 METs is light, 3 to 6 is moderate, above 6 is vigorous). The worked example uses the midpoint of the 80-90 kg band, 85 kg:
5 MET × 85 kg = 425 kcal per hour
For any other duration, multiply by the hours: calories = MET × weight (kg) × hours. A 30-minute session is half the hourly figure, a 90-minute session is one and a half times it, and the table below does that arithmetic for the common session lengths so you do not have to.
Your numbers at 85 kg
| Session length | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 5 × 85 × 0.25 | 106 kcal |
| 30 minutes | 5 × 85 × 0.50 | 212 kcal |
| 45 minutes | 5 × 85 × 0.75 | 319 kcal |
| 60 minutes | 5 × 85 × 1.00 | 425 kcal |
| 90 minutes | 5 × 85 × 1.50 | 638 kcal |
| 120 minutes | 5 × 85 × 2.00 | 850 kcal |
A useful way to read the table is backwards: to burn roughly 500 kcal from hunting alone at 85 kg you would need about 71 minutes. Three one-hour sessions a week come to about 1275 kcal a week from this activity, and five 45-minute sessions come to about 1594 kcal a week. Those weekly totals are the numbers that matter for weight management, because a single session is a small fraction of a week's energy balance — consistency across weeks is what moves body weight, not one heroic session.
Note also that the table scales linearly with weight. A heavier person burns more doing the same activity for the same time, because there is more body to move; a lighter person burns less. That is not a judgement about fitness — it is physics, and it is why every calories-burned figure on this site states the weight it was calculated at. If you weigh 10 kg more than the 85 kg example, add roughly 50 kcal per hour; 10 kg less, subtract the same.
How hunting compares at 85 kg
| Activity | MET | kcal per hour | kcal per 30 minutes |
|---|---|---|---|
| Hunting | 5 | 425 | 212 |
| Playing baseball | 5 | 425 | 212 |
| Playing softball | 5 | 425 | 212 |
| Kayaking | 5 | 425 | 212 |
| Walking briskly (4 mph) | 5 | 425 | 212 |
The comparison is the honest way to choose between activities. A higher MET is not automatically better: an activity you enjoy and repeat three times a week beats a harder one you quit after a fortnight, and joint-friendly options matter more than raw burn for anyone with knees or a back that complain. Use the table to see the trade-offs — for example, swapping a lower-MET activity for a higher one for the same 30 minutes — and then choose on enjoyment and sustainability, not on the biggest number.
How to use the result
Terrain and load are the two big variables. Flat farmland with a light kit is close to the 5.0 MET figure; steep, uneven ground with a pack and a harvested animal to carry pushes it higher. The waiting itself is light, so the day's total depends on the ratio of walking to waiting.
Start with the session you can actually repeat. If you are new to hunting, two or three 30-minute sessions a week (212 kcal each at 85 kg) is a sensible first month, adding 10 minutes a session each week rather than jumping straight to hour-long efforts. If you already do it regularly, the 60- and 90-minute rows are your planning numbers: block them into your week the way you would any other appointment, and track the sessions rather than the calories, because sessions are what you control.
For weight loss, the activity calories sit on top of your daily food intake, and the safe frame is a deficit of roughly 300–500 kcal a day, aiming for 0.5–1% of body weight per week. Never let the activity numbers talk you into eating far less: the safety floors are 1,200 kcal a day for women and 1,500 kcal a day for men, and any intake below those needs medical supervision. A 425-kcal session does not "earn" an extra meal of the same size, either — the body compensates, appetite rises after hard sessions, and the deficit that matters is the weekly average, not a single day's maths.
Practical tips specific to hunting: Break in your boots before a long day — rough ground in new boots is a reliable way to end a hunt early with blisters. Carry water and food even for a short outing; a day outdoors in cold or heat dehydrates you faster than you expect. Plan your route and tell someone where you are going, especially in remote or mountainous ground.
What the number does NOT tell you
MET values are population averages, and the error on any single person is real. The Compendium value was measured on a sample of adults, not on you, and it assumes a standard intensity: a relaxed game, a steady paddle, a moderate slope. If you push harder than the standard, you burn more; if you coast, you burn less. Heart-rate monitors and power meters estimate the same thing from different signals and disagree with each other by 10 to 20% on a good day, so treat every figure — including this page's — as accurate to roughly that band, not to the single calorie.
The figure also counts gross energy, which includes the calories you would have burned sitting still during that hour anyway. The extra burn above rest is the gross figure minus your resting rate for that hour (roughly 85 kcal for a 85 kg person at 1 MET), so the net cost of an hour of hunting is about 340 kcal, not 425. That distinction matters when you add activity calories to a daily total that already includes your resting metabolism — counting gross calories on top of a full BMR double-counts the resting hour.
Finally, the formula knows nothing about your body composition, fitness, or health. Muscle burns more than fat at rest, trained people are more efficient at a familiar activity (and therefore burn slightly less for the same work), and illness, heat, altitude, and medication all shift the real number. If you have a medical condition, are pregnant, or take medication that affects heart rate or metabolism, treat this page as background information and talk to a clinician before building a training or weight-loss plan around it.

Frequently asked questions
How many calories does hunting burn in 30 minutes at 85 kg?
About 212 kcal. The calculation is 5 MET × 85 kg × 0.5 hours = 212 kcal, from the 2011 Compendium value of 5 METs. It is an estimate: your real figure depends on how hard you push, and a relaxed session will come in lower.
Is hunting good for weight loss?
It can help, because at 425 kcal an hour it is a moderate-intensity activity that makes a real contribution to a weekly deficit — three hour-long sessions are about 1275 kcal a week. But weight loss is decided by the weekly energy balance, not by one activity, so the food side matters at least as much. Keep daily intake at or above 1,200 kcal (women) or 1,500 kcal (men) unless a clinician supervises a lower intake.
How long do I need to go hunting to burn 500 calories?
About 71 minutes at 85 kg at the standard intensity. Splitting it across days is fine — two 45-minute sessions and one shorter one add up to the same total, and shorter, more frequent sessions are easier to sustain.
Is hunting good exercise?
It can be. A day of walking rough ground with a pack is solid moderate exercise, and the carrying adds a strength element. But a day spent mostly sitting in a stand is light activity at best — the exercise value of hunting depends entirely on how much of the day you spend moving.
How many calories does a full day of hunting burn?
That depends on the hours spent moving versus waiting. As a rough guide, eight hours at the 5.0 MET average would be about 40 times the hourly figure on this page, but real hunting days mix waiting (much lower) with walking and carrying (higher), so treat any day total as a very rough estimate.
Can I count hunting towards the weekly activity guidelines?
Yes — at 5 METs it counts as moderate-intensity activity, so it contributes to the guideline of 150 minutes of moderate activity a week. Five 30-minute sessions would give you 150 minutes of moderate activity; two or three longer sessions can reach the same total.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
