How Many Calories Does Walking a Mile Burn?
Walking one mile burns approximately 80 to 100 calories for a typical adult — roughly 88 kcal for someone weighing 68 kg (150 lb) and about 117 kcal for someone weighing 91 kg (200 lb). Body weight is the single largest driver of that number, followed by terrain and pace.
Why Body Weight Is the Biggest Variable
Calories burned during locomotion depend on how much mass you move through space. Exercise physiologists use the MET (metabolic equivalent of task) system to standardise this. Moderate-pace walking (3.0-3.5 mph on flat ground) carries a MET value of approximately 3.5 according to the Compendium of Physical Activities.
The formula is:
Calories per minute = MET x body weight (kg) x 0.0175
A 68 kg adult walking at 3.5 mph (MET 3.5) burns about 4.2 kcal per minute. A typical mile at that pace takes around 17-18 minutes, yielding roughly 72-75 kcal from movement plus baseline metabolic rate — netting out to approximately 88 kcal per mile above rest.
Per-Mile Burn Estimates by Body Weight
The table below applies a MET of 3.5 (flat-ground, moderate-pace walking) across common body weights. These figures represent net calories above resting metabolism for one mile.
| Body weight | Approx. pace | Calories per mile |
|---|---|---|
| 55 kg (121 lb) | 17-18 min/mi | ~70 kcal |
| 68 kg (150 lb) | 17-18 min/mi | ~88 kcal |
| 82 kg (180 lb) | 17-18 min/mi | ~105 kcal |
| 91 kg (200 lb) | 17-18 min/mi | ~117 kcal |
| 104 kg (230 lb) | 17-18 min/mi | ~134 kcal |
Adding a modest hill (5-8% grade) increases per-mile burn by 15-25% because the vertical work raises the effective MET toward 5.0-6.0. Carrying a weighted backpack adds a further 5-10% per 10 kg of load, consistent with ACSM metabolic equations.
Walking and the 3,500-Calorie Rule
The commonly cited figure of 3,500 kcal per pound of fat (roughly 7,700 kcal per kilogram) comes from foundational work by Max Wishnofsky published in 1958 and still referenced in NIH materials. It is an approximation — real fat tissue is about 87% lipid by weight, and actual weight-loss curves depend on adaptive thermogenesis and body composition changes — but it remains a useful planning anchor.
Practical implications for a 68 kg person targeting a 500 kcal daily deficit (the standard recommendation in the 2020-2025 Dietary Guidelines for Americans for roughly 0.5 kg per week of loss):
- Walking alone: would require approximately 5.7 miles daily — achievable but demanding.
- Walking 2 miles daily (~175 kcal) combined with a 325 kcal food deficit: hits the 500 kcal target more comfortably without requiring excessive daily step counts.

How Protein Fits In
When walking creates a calorie deficit, protein intake determines how much of the weight lost comes from fat versus lean mass. The ISSN (International Society of Sports Nutrition) recommends 1.6-2.2 g of protein per kg of body weight for active individuals aiming to preserve muscle during a deficit. For a 68 kg adult that is 109-150 g of protein per day.
Walking at low-to-moderate intensity (MET under 5) is primarily aerobic and does not strongly stimulate muscle protein synthesis, which makes dietary protein all the more important for maintaining metabolic rate during a prolonged walking-based weight-loss plan. For a full breakdown of how protein targets interact with energy deficits, see our post on protein targets for weight loss.
How to Apply This to Your Routine
- Establish your daily mile burn. Multiply your body weight in kg by 1.3 to get a rough per-mile calorie figure (e.g., 68 kg x 1.3 = 88 kcal).
- Pick a realistic daily walk target. Two to three miles per day is achievable for most people and contributes 175-350 kcal toward a deficit without dominating the day.
- Pair walking with a moderate food reduction. Closing the remaining gap — typically 150-325 kcal — through portion awareness is more sustainable than walking five or more miles daily.
- Track what you eat, especially post-walk. A single smoothie or energy bar after a two-mile walk commonly exceeds the calories just burned. Logging your meals closes that feedback loop.
The math is straightforward; execution is where most plans lose ground. Accurate food logging beside consistent walking is the combination that the evidence supports.

Frequently asked questions
- How many calories does walking a mile burn?
- Most adults burn 80-100 calories per mile walking at a moderate pace. A 68 kg (150 lb) person burns roughly 88 kcal per mile; a 91 kg (200 lb) person burns closer to 117 kcal per mile, based on MET-based calculations validated against indirect calorimetry.
- Does walking speed change the calories burned per mile?
- Surprisingly little — total calories per mile stay similar across walking speeds of 3.0-4.0 mph because a slower pace means more time at lower intensity while a faster pace means less time at higher intensity. Above 4.5 mph the calorie cost per mile rises noticeably as the gait becomes inefficient.
- How many miles must I walk each day to lose one pound per week?
- One pound of fat represents approximately 3,500 kcal. To lose it in seven days purely through walking, a 68 kg person would need to walk roughly 40 miles per week, or about 5-6 miles daily. In practice, combining a moderate calorie deficit with 3-4 miles of walking daily is a more sustainable approach.
