To lose weight by walking, aim for at least 150 minutes of brisk walking a week, and work up to 250-300 minutes a week (about 35-45 minutes a day) if walking is doing most of the work. The American College of Sports Medicine found that more than 250 minutes a week of moderate activity was linked to clinically meaningful weight loss.
Pair the walking with a modest calorie cut. A 155-lb (70 kg) person burns about 175 calories in 30 minutes of brisk walking, so food still decides most of the result.
Key takeaways
- 150-250 minutes a week brings modest weight loss; more than 250 is where loss becomes meaningful.
- Calories: about 150-235 per 30 brisk minutes at 130-205 lb, depending on your weight.
- A pound of fat takes roughly 35-50 miles of brisk walking, so combine walking with eating a little less.
- Pace matters less than time and distance. Hills add the most per minute.
How much should you walk a day to lose weight?
The CDC recommends at least 150 minutes a week of moderate activity such as brisk walking for health. For weight loss, the 2009 ACSM position stand found that 150-250 minutes a week gives only modest loss on its own, helps when combined with a moderate diet, and that more than 250 minutes a week is linked to clinically significant loss.
Here's what those amounts burn for a 155-lb (70 kg) person walking at 3.5 mph. "Above resting" is the extra the walk adds, which is the number that counts toward a deficit.
| Walking per week | Per day (7 days) | Calories burned (kcal) | Above resting (kcal) | Fat equivalent, rough |
|---|---|---|---|---|
| 150 min | about 21 min | 886 | 701 | 0.2 lb (0.1 kg) |
| 250 min | about 36 min | 1,476 | 1,169 | 0.3 lb (0.15 kg) |
| 300 min | about 43 min | 1,772 | 1,402 | 0.4 lb (0.2 kg) |
The fat column uses the rough rule of 3,500 calories per pound, which overstates loss over months. Walking alone gets you a steady but slow result. Add a daily cut of 250-500 calories from food (1,750-3,500 a week) and your weekly deficit grows several times over. Use the calorie deficit calculator to set the food side, or read how to calculate a calorie deficit.
Calories burned walking by weight and pace
Calories in 30 minutes, from the 2024 Compendium of Physical Activities (calories = MET x 3.5 x body weight in kg / 200 x minutes). These include the calories you'd burn at rest.
| Pace (Compendium code, MET) | 130 lb (59 kg) | 155 lb (70 kg) | 180 lb (82 kg) | 205 lb (93 kg) |
|---|---|---|---|---|
| Slow, 2.0-2.4 mph (17152, 2.8) | 87 | 103 | 120 | 137 |
| Moderate, 2.8-3.4 mph (17190, 3.8) | 118 | 140 | 163 | 186 |
| Brisk, 3.5-3.9 mph (17200, 4.8) | 149 | 177 | 206 | 234 |
| Very brisk, 4.0-4.4 mph (17220, 5.5) | 170 | 203 | 236 | 269 |
| Uphill 1-5% grade (17034, 5.3) | 164 | 196 | 227 | 259 |
| Uphill 6-10% grade (17035, 7.0) | 217 | 258 | 300 | 342 |
Double the numbers for an hour. Heavier people burn more for the same walk, which is why weight loss from walking slows a little as you get lighter. For other activities, try the calories burned calculator.
How many miles do you have to walk to lose a pound?
Per mile, the calories above resting are what matter for fat loss.
| Body weight | Per mile at 3 mph, above resting (kcal) | Per mile at 3.5 mph, above resting (kcal) | Miles per pound of fat at 3.5 mph, rough |
|---|---|---|---|
| 130 lb (59 kg) | 58 | 67 | 52 |
| 155 lb (70 kg) | 69 | 80 | 44 |
| 180 lb (82 kg) | 80 | 93 | 38 |
| 205 lb (93 kg) | 91 | 106 | 33 |
So walking 4 miles a day at 3.5 mph adds about 320 calories a day for a 155-lb person, or about 2,240 a week. That's a little over half a pound, if your eating doesn't change. To burn 500 calories in total, the same person needs about 85 minutes at 3.5 mph; at 180 lb it's about 73 minutes.
Do you have to walk fast to lose weight?
No. Per mile, walking faster burns only a little more: for a 155-lb person, about 69 calories above resting at 3 mph, 80 at 3.5 mph, 83 at 4 mph and 98 at 4.5 mph. Per minute the difference is larger, so a faster pace helps most when your time is short.
Hills are the best upgrade. A 155-lb person burns about 140 calories in 30 minutes on flat ground at 3 mph, 196 on a 1-5% grade and 258 on a 6-10% grade. On a treadmill, the incline button does the same job. Pick the pace you can keep up for the planned time; adding minutes and hills beats a speed you dread.
What about 10,000 steps a day?
At a normal 3 mph pace, a mile is about 2,270 steps; at 3.5 mph it's about 2,080. So 10,000 steps is roughly 4.4 miles and 88 minutes, and burns about 410 calories for a 155-lb person. Our page on 10,000 steps calories breaks it down by weight and speed, and 15,000 steps a day goes further.
The 10,000 target itself has limited scientific basis. For health, the benefit levels off earlier:
- A 2022 analysis of 15 studies (47,471 adults) found the risk of dying kept falling up to about 6,000-8,000 steps a day in people 60 and older, and 8,000-10,000 in younger adults.
- A 2019 study of 16,741 older women found the benefit leveled off at about 7,500 steps a day.
- A 2023 meta-analysis of 226,889 people linked each extra 1,000 steps a day to a 15% lower risk of death.
For weight loss, think in minutes of purposeful walking each week, plus everyday steps on top.
Why walking alone often isn't enough
Exercise at public-health levels tends to produce modest weight loss, about 2 kg (4.4 lb) on average in a 2014 review, with big differences between people. Two things usually explain it:
- Eating creeps up. A 30-minute walk burns about 175 calories for a 155-lb person. A large flavored coffee or a handful of snacks replaces it.
- Burn gets overestimated. In a Stanford test of seven wrist devices, none estimated calories burned with less than 20% error.
Walking still helps you keep weight off once it's gone, and it's good for your heart. It just works best alongside a food plan. Our guide to cardio vs strength training for fat loss explains how to add lifting, which helps you keep muscle while you lose fat.
A 12-week walking plan for weight loss
Build time first, then pace and hills. If you're starting from very little activity, or have a heart, joint or other health condition, talk to your doctor before you start.
| Weeks | Minutes per walk | Walks per week | Weekly total | Pace and focus |
|---|---|---|---|---|
| 1-2 | 20 | 5 | 100 min | Comfortable, you can talk easily |
| 3-4 | 30 | 5 | 150 min | Brisk, you can talk but not sing |
| 5-6 | 35 | 6 | 210 min | Brisk; add one hilly route |
| 7-8 | 40 | 6 | 240 min | 2 walks with 2 min brisk / 1 min fast intervals |
| 9-10 | 45 | 6 | 270 min | 2 hill or incline sessions |
| 11-12 | 45-50 | 6-7 | about 300 min | Keep one longer walk of 60 min |
Splitting a walk into two shorter ones counts the same. Recalculate your calorie target as your weight drops, because you'll burn a little less per mile.
Walking vs running for weight loss
Running burns about twice as much per minute: a 155-lb person burns about 343 calories in 30 minutes running at 6 mph, against 177 walking briskly. Per mile the gap is smaller, about 102 calories above resting for running against 80 for brisk walking. See running calories for the full tables.
If you enjoy running and your joints are fine with it, it saves time. If you'll actually walk every day but would quit running in a month, walk.
