“You can’t outrun a bad diet” gets repeated so often it has almost stopped meaning anything. So here are the actual numbers, side by side, for how many calories different activities burn and how many different foods add.
We’ve also explained what this guide means for those taking or thinking about taking a GLP-1 medication for weight loss. Some people think you don’t need to exercise on a GLP-1, but that’s simply not true. Anyone on semaglutide or tirzepatide needs a narrower version of this: how much protein on a GLP-1, and whether exercise on Ozempic still earns the hour once the medication is doing the work.
Some of them will annoy you. That is the point. Most people have no idea how little a single workout moves the needle compared with one extra muffin, and the fitness industry has no incentive to tell them.
Exercise calories burned are unique to each individual
The figures on this page represent an approximation for an adult of about 155 pounds (70 kg). Calorie burn varies with body weight, so a 200-pound person doing the same 30-minute walk burns roughly a third more than a 150-pound person, and a 120-pound person burns even less. Fitness level matters too, as does terrain, temperature, and intensity.
Nobody, including the treadmill display and your watch, can give you a precise number. Use these as ballpark figures for comparison, not as gospel.
How much of your total daily calorie burn is from exercise?
Your resting metabolism, or what it costs to keep a human alive doing nothing, burns most of your total daily energy expenditure. Physical activity typically accounts for something like 15%–30% percent of the total, and formal exercise is only a portion of that.
An hour in the gym can end up worth about one slice of pizza. That does not make the hour worthless, but it does mean movement works best alongside what you eat rather than as a way of canceling it out. One also must not discount the cardiovascular and other benefits of exercise besides weight loss alone.
What drives the number
- Body weight: Moving heavier mass costs more energy, which is why the same walk burns less as you lose weight.
- Intensity: Sprinting burns far more per minute than strolling, though it’s harder to sustain for long periods.
- Duration: A long, easy effort often beats a short, brutal one on total calories though may not have the same cardiovascular benefits.
- Fitness: Trained athletes tend to exercise more efficiently, so they burn slightly less doing the same task. A tragic physiological irony is that the fitter you are, the harder you have to work to burn calories.
Researchers standardize this with METs, or metabolic equivalents. One MET is roughly what you burn at rest. A 4 MET activity costs about four times your resting rate. The published MET tables behind most calorie calculators come from the Compendium of Physical Activities (Ainsworth et al., 2011).
How much protein do you need on a GLP-1?
As you can see by the table below, exercise as a tool for weight loss is often less powerful than people realize. On its own, that is. However, when you’re on a GLP-1, it’s truer than ever because of how weight falls off. When semaglutide or tirzepatide drops your calorie intake, a lower protein intake may result, which can cause muscle loss either in addition to or instead of fat loss.
This makes resistance training, as well as protein intake, important for GLP-1 users.
Aim for light-to-moderate weight lifting two or three times a week, and you’ll get more bang for your buck if you do it before cardio. This is in addition to prioritizing your protein intake as much as you can on a suppressed appetite.
Despite slightly different needs for the GLP-1 patient, exercise is still key to overall wellness, even if weight loss from exercise isn’t the sole goal, and the calorie-burn figures from a 30-minute exercise are still accurate.
Calories burned in 30 minutes
All figures are estimates for a 155-pound (70 kg) adult, with the kilojoule equivalent in parentheses.
Light
| Activity | 30 minutes |
|---|---|
| Sleeping | about 35 calories (145 kJ) |
| Sitting quietly | about 45 calories (190 kJ) |
| Standing | about 65 calories (270 kJ) |
| Gentle stretching or slow yoga | about 90 calories (375 kJ) |
| Light housework | about 95 calories (400 kJ) |
| Slow walking, 2 mph | about 100 calories (420 kJ) |
Moderate
| Activity | 30 minutes |
|---|---|
| Brisk walking, 3.5 mph | about 150 calories (630 kJ) |
| Mowing the lawn or yard work | about 175 calories (730 kJ) |
| Dancing | about 175 calories (730 kJ) |
| Swimming, easy pace | about 210 calories (880 kJ) |
| Cycling, 10 mph | about 240 calories (1,000 kJ) |
Vigorous
| Activity | 30 minutes |
|---|---|
| Circuit training or interval work | about 280 calories (1,170 kJ) |
| Running, 5 mph | about 290 calories (1,215 kJ) |
| Rowing, vigorous | about 300 calories (1,255 kJ) |
| Basketball or soccer, playing a game | about 300 to 350 calories (1,255 to 1,465 kJ) |
| Jumping rope | about 380 calories (1,590 kJ) |
Food-to-exercise equivalents
- A medium latte with 2% milk: Roughly 150 calories (630 kJ) equal about a 30-minute brisk walk.
- A 5-ounce glass of wine: Roughly 125 calories (525 kJ) equal about 40 minutes of gentle yoga.
- A standard candy bar: Roughly 250 calories (1,050 kJ) equal nearly an hour of brisk walking.
- A Big Mac: Around 590 calories (2,470 kJ) equal about an hour of running at 5 mph. Add fries and a soda and you’re approaching a half-marathon.
You can look up the calorie content of almost anything in the USDA’s FoodData Central database, which is where most of the numbers you see quoted online originally come from.
These figures aren’t meant to food shame but rather to help you balance your dietary intake with exercise without expecting a workout to erase a meal, which it usually cannot.
Why exercise still earns its place
If those numbers made you want to skip the gym, hold on. Exercise isn’t only about counting the calories you burned. Its other benefits can directly and indirectly impact weight as well. Here are a few less obvious ways exercise contributes to weight loss:
- Resistance training preserves muscle while you lose fat, which changes what you lose and where, rather than how much (Willis et al., 2012).
- Regular activity improves insulin sensitivity and blood pressure, often before the scale changes at all.
- Movement helps sleep, and sleep helps appetite regulation (Taheri et al., 2004).
- Exercise reliably improves mood, which can help control cravings and emotional eating.
The federal Physical Activity Guidelines for Americans recommend 150 to 300 minutes of moderate activity a week, or 75 to 150 minutes of vigorous activity, plus muscle-strengthening work on two or more days. Every one of those recommendations is justified on health outcomes, not on calorie burn alone.
The movement you are not counting
Most people track the 45 minutes they spend in a gym and ignore the other fifteen and a half waking hours. That’s backwards! All the incidental movement in your day, walking to the mailbox, standing at the counter, cleaning, pacing while you talk, adds up to a category researchers call non-exercise activity thermogenesis, and it varies wildly from person to person (Levine, 2007).
Three brisk 15-minute walks across a day come to roughly 225 calories (940 kJ), which is more than many people get from a gym session they had to drive to. Frequency beats perfection here.
Why exercise alone rarely works for weight loss
If you’ve spent weeks exercising daily only to see no movement on the scale, or worse, upward movement, you know too well that exercise alone won’t cut it for most people. But why is that?
Two things get in the way.
First, vigorous exercise makes you hungry, which can then jeopardize the calorie deficit you earned by exercising. Second, your body quietly compensates by reducing energy spent elsewhere, so total daily expenditure climbs less than it otherwise would have (Pontzer et al., 2016).
A GLP-1 medication lowers appetite overall, which changes how to balance training against the calories you burn. It makes it easier to achieve the calorie deficit necessary for weight loss.
This is why people who train harder without changing how they eat so often stall and then conclude something is wrong with them—and give up. Nothing is wrong with them. They simply don’t have all the information they need.
Practical takeaways
- 20–30 minutes most days will do more for you over a year than one heroic weekend session.
- Combine some resistance work with some cardio. They do different jobs, and each enhances the effects of the other.
- Pay attention to your movement outside your workouts, since for most people it is the larger number.
- Don’t use exercise to “pay off” food. It rarely balances, and it turns something good for you into a chore you resent. Rather, see nutrient-dense food as the fuel you need to move your body.
