Ever eaten a slice of pizza and wondered what it would take to work it off? The short answer, for a 150 lb (68 kg) person, is about 24 minutes of running at 6 mph — or about 73 minutes of walking at 3 mph. This calculator turns any snack into exercise minutes for your body weight, so you can see the trade-off before you order. For your total daily burn, start with our calories burned calculator and our TDEE calculator.
Because running burns about three times the calories per minute that easy walking does, the same slice of pizza costs 24 minutes of running but 73 minutes of walking for a 150 lb person. Pick your food and weight below to see all four activities side by side.
| Activity | Burn rate | Time to burn it off |
|---|
Burn-off time is simply the food's calories divided by how fast you burn calories during an activity, and that burn rate comes from the activity's MET value and your body weight. One MET is the energy you use at rest; walking at 3 mph is 3.3 METs, brisk walking at 4 mph is 5 METs, running at 6 mph is 10 METs, and moderate cycling is 8 METs. Multiply the MET value by 3.5 and by your weight in kilograms, divide by 200, and you get calories burned per minute — then divide the food's calories by that rate to get minutes.
| Activity | MET value | Formula (kcal/min) |
|---|---|---|
| Walking, 3 mph | 3.3 | 3.3 × 3.5 × weight (kg) ÷ 200 |
| Brisk walking, 4 mph | 5 | 5 × 3.5 × weight (kg) ÷ 200 |
| Running, 6 mph | 10 | 10 × 3.5 × weight (kg) ÷ 200 |
| Cycling, moderate | 8 | 8 × 3.5 × weight (kg) ÷ 200 |
Weight is the lever most people miss. A 200 lb (91 kg) person burns about a third more calories per minute than a 150 lb (68 kg) person doing the same activity, so the same donut takes roughly 19 minutes of running for the heavier person versus about 25 minutes for the lighter one. That is not a reward for weighing more — it is physics: moving a heavier body costs more energy. The MET values used here are the standard published values from the Compendium of Physical Activities, the same source behind most calorie-burn tables in the US and UK.
These are typical values for standard servings — a restaurant slice, a regular burger, a medium fries — and real portions vary, sometimes a lot. A loaded pizza slice or a double burger can run 100–200 kcal above the table value, which adds roughly 8–17 extra running minutes for a 150 lb person. If you know the exact number from a label or a menu, use the custom calories box for a sharper answer.
| Food | Typical serving | Calories |
|---|---|---|
| Pizza slice | 1 medium slice | 285 kcal |
| Burger | 1 regular burger | 550 kcal |
| Donut | 1 glazed donut | 300 kcal |
| Soda can | 12 fl oz (355 ml) | 140 kcal |
| Fries, medium | 1 medium serving | 365 kcal |
| Chocolate bar | 1 standard bar | 235 kcal |
| Ice cream, one scoop | 1 scoop | 140 kcal |
| Cookie | 1 large cookie | 160 kcal |
| Latte | 1 medium, whole milk | 190 kcal |
| Bagel | 1 plain bagel | 280 kcal |
| Burrito | 1 large restaurant burrito | 650 kcal |
| Beer | 12 fl oz (355 ml) | 150 kcal |
Example 1 — 150 lb person, one pizza slice (285 kcal). First convert weight: 150 lbs × 0.4536 = 68.0 kg. Running at 6 mph: 10 × 3.5 × 68.0 ÷ 200 = 11.9 kcal/min, so 285 ÷ 11.9 = 23.9 minutes, about 24 minutes. Walking at 3 mph: 3.3 × 3.5 × 68.0 ÷ 200 = 3.9 kcal/min, so 285 ÷ 3.9 = 72.5 minutes, about 73 minutes. Brisk walking (5 METs) gives 5.95 kcal/min and about 48 minutes; moderate cycling (8 METs) gives 9.5 kcal/min and about 30 minutes.
Example 2 — 180 lb person, one burger (550 kcal). Weight: 180 lbs × 0.4536 = 81.6 kg. Walking at 3 mph: 3.3 × 3.5 × 81.6 ÷ 200 = 4.7 kcal/min, so 550 ÷ 4.7 = 116.6 minutes, about 117 minutes. Running at 6 mph: 10 × 3.5 × 81.6 ÷ 200 = 14.3 kcal/min, so 550 ÷ 14.3 = 38.5 minutes, about 39 minutes. The burger is the clearest warning in the table: nearly two hours of walking, or a hard 39-minute run, for a single item.
Example 3 — 200 lb person, one donut (300 kcal), running. Weight: 200 lbs × 0.4536 = 90.7 kg. Running: 10 × 3.5 × 90.7 ÷ 200 = 15.9 kcal/min, so 300 ÷ 15.9 = 18.9 minutes, about 19 minutes. The same donut takes a 150 lb runner about 25 minutes (300 ÷ 11.9 = 25.2), which shows the weight effect in a single line.
Every number on this page is an estimate, not a meter reading. MET values are population averages: your actual burn depends on your fitness, your running efficiency, hills, wind, and whether you fidget afterward. Treat the result as accurate within roughly 10–20%, and treat the comparison between activities — running is about three times as costly per minute as easy walking — as the reliable part.
The bigger lesson is about diet, not exercise. A 650 kcal burrito needs about 55 minutes of running for a 150 lb person, and a burger plus fries plus a soda (about 1,055 kcal) needs roughly an hour and a half of running. Nobody sustains that kind of "eat it, then erase it" math day after day, and trying usually ends in guilt, not fitness. Exercise earns its keep by building strength, protecting your heart, improving sleep, and lifting your mood — the food side of the equation is handled far more easily by portion choices than by extra miles. If weight loss is the goal, pair this perspective with our weight loss calculator and calorie deficit calculator rather than chasing individual foods with workouts.
Use the table as a decision tool, not a punishment ledger. If the burger costs 117 walking minutes and you have 30 minutes at lunch, the honest options are a smaller portion, a walk plus a lighter dinner, or simply enjoying the burger and moving on — all three beat a guilt-driven two-hour slog. A practical habit that works for many people: a 10-minute walk after meals. It will not "burn off" a pizza, but it blunts the blood-sugar spike, aids digestion, and adds up to 70 minutes of easy movement a week without ever feeling like a workout. Save the running column for days you already run; do not start running to pay for food, especially if you are new to it — build up with our walking calories calculator first.
