QUICK ANSWER
Walking burns roughly 80 to 100 calories per mile for most people, depending on body weight and pace. A 30-minute brisk walk typically burns between 150 and 200 calories. Combined with a modest calorie balance, walking consistently every day can produce meaningful changes in body composition over weeks and months. The calculator below gives you a personalised estimate based on your specific numbers.

How to Use Your Walking Calculator Results
The calculator gives you three main numbers: calories burned per session, total weekly calories burned if you walk every day, and an estimated weekly change in body weight based on your walking alone. The calorie figure is based on the MET (Metabolic Equivalent of Task) value for your chosen walking pace, multiplied by your body weight in kilograms and the duration of your walk. MET values are published by the Compendium of Physical Activities, a research database used by sports scientists and public health organisations worldwide. The weekly calorie total shows you what consistent daily walking adds up to across seven days. This is useful because individual sessions can feel modest, but the compounding effect over a week becomes quite significant, particularly for people who were previously sedentary. The estimated weekly weight change is based on the principle that a sustained deficit of roughly 3,500 calories corresponds to approximately one pound of body fat. This figure assumes walking is the only change you are making, with food intake staying the same. In practice, most people find their appetite changes slightly when they start walking regularly, so real-world results vary.
Why Walking is One of the Most Effective
Exercise Habits You Can Build
Walking gets overlooked in favour of more intense exercise, but the research on its long-term benefits for health and body composition is genuinely impressive. A large study published in JAMA Internal Medicine tracking over 16,000 women found that higher daily step counts were associated with significantly lower mortality rates, with benefits plateauing at around 7,500 steps per day. Research from the University of Utah found that every additional 2,000 steps per day reduced mortality risk by roughly 10 percent. For body composition specifically, walking has several practical advantages over more intense exercise. It is low impact, meaning most people can do it every day without significant recovery time. It does not significantly suppress appetite in the way that intense training sometimes can. And it is accessible: no gym membership, no special equipment, no skill requirement. The key variable is consistency. A 30-minute walk every day for a year produces far more cumulative calorie expenditure than sporadic intense exercise sessions with days of rest in between. Walking also tends to be sustainable long term because it does not feel punishing, which means people actually stick to it. For people who are new to regular exercise, walking is often the single best starting point. It creates the habit of daily movement without the physical stress that comes from jumping straight into high-intensity training.Water fasting is not suitable for everyone and it does carry real risks if done without proper awareness. Here is what the research says about fasting safely. Fasting for up to 24 hours is generally considered safe for healthy adults who are not pregnant, not diabetic and not on medication that requires food intake. Beyond 24 hours, the risks increase and medical supervision becomes advisable for most people. The main risks of extended water fasting include electrolyte imbalances which can affect heart rhythm and muscle function, refeeding syndrome when food is reintroduced too quickly, dizziness and fainting from low blood pressure, and muscle loss if the fast extends beyond 48 to 72 hours. The most common mistake people make is breaking a long fast with a large, carbohydrate-heavy meal. This causes a rapid spike in insulin and can be genuinely dangerous after a fast of more than 3 days. Refeeding should be gradual, starting with small amounts of easily digestible food such as diluted juice, broth or small portions of soft fruit. If you have any underlying health condition, including high blood pressure, type 1 or type 2 diabetes, a history of eating disorders, or heart disease, please speak to a doctor before attempting any extended water fast.

Frequently Asked Questions
About Walking for Weight Loss
How many calories do you burn walking for 30 minutes?
A 30-minute brisk walk at around 3.5 mph burns approximately 150 to 200 calories for most adults, depending on body weight and exact pace. Heavier individuals burn more calories for the same distance because they are moving more mass. The calculator above gives you a personalised figure based on your specific weight and pace.
How much weight can you lose by walking every day?
Walking every day without changing anything else can produce roughly 0.5 to 1 pound of weight loss per week for many people, depending on the duration and pace of walks and starting body weight. This estimate assumes a 30 to 45 minute brisk walk each day. Longer or faster walks, or combining walking with modest dietary adjustments, can increase this rate.
Does walking really help you lose weight?
Yes, consistently. Research published in journals including JAMA Internal Medicine and Obesity shows clear associations between regular walking and reductions in body weight and body fat. Walking is particularly effective for people new to exercise and for long-term weight maintenance because it is sustainable, low impact and accessible every day without recovery concerns.
Is walking better than running for weight loss?
Running burns more calories per minute than walking, so it produces faster results in less time. However, walking can be done every single day for most people without the recovery demands that running creates, and many people find it far easier to maintain as a long-term habit. Over a year, a daily 30-minute walk and a three-times-weekly run may produce comparable total calorie expenditure for many individuals.
How many steps a day do you need to lose weight?
Research suggests that 7,000 to 10,000 steps per day is associated with meaningful health benefits and can contribute to weight management when combined with an appropriate diet. The calorie burn from 10,000 steps is approximately 300 to 500 calories for most people, which over a week adds up significantly. Even 5,000 additional steps above your current baseline produces a measurable increase in daily energy expenditureLight exercise such as walking and gentle stretching is generally fine during a short water fast. Intense exercise is not recommended because it increases the risk of dizziness, low blood sugar and electrolyte depletion. Stop immediately if you feel lightheaded or unwell.
Does walking speed affect how many calories you burn?
Yes, significantly. A faster pace increases your MET (Metabolic Equivalent of Task) value, which directly increases calorie burn per unit of time. Walking at 4 mph burns roughly 40 to 50 percent more calories per minute than walking at 2.5 mph. However, at lower speeds you are also covering less distance per session, so the total calorie burn depends on both how fast and how long you walk.
Is it better to walk on an incline for weight loss?
Walking uphill or on an incline significantly increases calorie burn compared to flat walking at the same speed. A 5 to 10 percent incline can increase calorie expenditure by 30 to 50 percent for the same pace and duration. If you use a treadmill, increasing the incline is one of the most effective ways to raise the intensity of your walk without increasing speed.
How accurate is this walking calculator?
This calculator uses published MET values from the Compendium of Physical Activities, which is the standard reference for exercise calorie estimation used by researchers and public health organisations. Results are a good estimate for most people but will vary based on individual fitness levels, terrain, walking form and metabolic rate. Use the result as a reliable guide rather than an exact figure.
