How Much To Run to Lose Weight: A Guide to Effective and Sustainable Weight Loss


Losing weight is a common goal for many people, and running is a popular form of exercise that can help you achieve this goal. However, determining how much to run in order to lose weight can be a confusing task. There are several factors that come into play, such as your current weight, fitness level, and diet. In this article, we will provide a comprehensive guide to help you calculate how much to run in order to lose weight effectively and sustainably.

Factors Affecting Weight Loss

Before we dive into the specifics of how much to run, it’s important to understand the factors that affect weight loss:

  1. Caloric Deficit: In order to lose weight, you need to consume fewer calories than you burn. This is known as a caloric deficit.
  2. Metabolism: Your metabolism plays a role in how many calories you burn each day. Some people naturally have a higher metabolism, meaning they burn more calories at rest.
  3. Body Composition: Muscle burns more calories than fat, so individuals with a higher muscle mass tend to burn more calories.
  4. Overall Activity Level: The more active you are throughout the day, the more calories you will burn.

Calculating Caloric Deficit

In order to calculate how much to run to lose weight, you need to determine your caloric deficit. This can be done by calculating your Basal Metabolic Rate (BMR) and factoring in your activity level.

BMR Calculation:

To calculate your BMR, you can use the Harris-Benedict equation:

For Men:
BMR 88.362 (13.397 x weight in kg) (4.799 x height in cm) – (5.677 x age in years)
For Women:
BMR 447.593 (9.247 x weight in kg) (3.098 x height in cm) – (4.330 x age in years)

Once you have calculated your BMR, you can adjust it based on your activity level:

Activity Level Multiplier
Sedentary (little to no exercise) 1.2
Lightly active (light exercise/sports 1-3 days/week) 1.375
Moderately active (moderate exercise/sports 3-5 days/week) 1.55
Very active (hard exercise/sports 6-7 days a week) 1.725
Extra active (very hard exercise/sports physical job or 2x training) 1.9

Multiply your BMR by the appropriate activity level multiplier to determine your Total Daily Energy Expenditure (TDEE).

Next, you need to determine your desired caloric deficit. A moderate caloric deficit is often recommended for safe and sustainable weight loss. Aim for a deficit of 500-1000 calories per day, which can lead to a weight loss of 1-2 pounds per week.

Once you have determined your desired caloric deficit, subtract this from your TDEE to calculate your daily calorie intake for weight loss.

Calculating Calories Burned from Running

Now that you have determined how many calories you need to consume in order to lose weight, let’s calculate how many calories you can burn from running.

The number of calories burned from running varies based on your weight, running speed, and duration.

A general estimate is that you burn about 100 calories per mile when running. However, this can vary depending on your weight.

You can use the following formula to calculate the calories burned from running:

Calories burned (body weight in kg) x (distance in km) x (calories burned per kg per km)

It’s important to note that this formula provides a rough estimate and may not be entirely accurate for everyone. Factors such as running form, terrain, and individual differences can also affect the number of calories burned.

How Much to Run for Weight Loss

Now that you have calculated your daily calorie intake for weight loss and the calories burned from running, you can determine how much to run to achieve your weight loss goals.

The formula to calculate how much to run for weight loss is as follows:

Distance in km (caloric deficit – calories burned from running) / (calories burned per kg per km)

Let’s say your daily caloric deficit is 500 calories and you burn 100 calories per km when running. To calculate the distance you need to run:

Distance in km (500 – 100) / 100 4 km

So, you would need to run 4 km per day to achieve a caloric deficit of 500 calories.

Tips for Effective and Sustainable Weight Loss

While running can be an effective way to lose weight, it’s important to approach weight loss in a sustainable and healthy manner. Here are some tips to help you achieve your weight loss goals:

  1. Gradually increase your running distance and intensity to avoid injuries.
  2. Include strength training exercises in your routine to build muscle and boost your metabolism.
  3. Focus on consuming nutritious, whole foods that are rich in vitamins and minerals.
  4. Stay hydrated by drinking plenty of water throughout the day.
  5. Get enough sleep to support your overall health and weight loss efforts.
  6. Seek support from a healthcare professional or a registered dietitian for personalized guidance.
  7. Stay consistent with your exercise and eating habits to see long-term results.

Frequently Asked Questions (FAQs)

Q1. How often should I run to lose weight?

A1. The frequency of your runs depends on your current fitness level and schedule. Aim for at least three to four days of running per week to see results.

Q2. Can I lose weight just by running?

A2. While running can contribute to weight loss, it’s important to combine it with a balanced diet and other forms of exercise for optimal results.

Q3. How long should my runs be for weight loss?

A3. The duration of your runs depends on your fitness level and goals. Start with shorter runs and gradually increase the distance over time.

Q4. What should I eat before and after running?

A4. Before running, opt for a light snack that includes carbohydrates and a small amount of protein. After running, focus on consuming a balanced meal that includes protein, carbohydrates, and healthy fats to aid in recovery.

Q5. Can running help me lose belly fat?

A5. Running can contribute to overall fat loss, including belly fat. However, spot reduction of fat is not possible, so it’s important to combine running with a balanced diet and strength training exercises for best results.

Q6. How long will it take to see weight loss results from running?

A6. The rate at which you see weight loss results can vary depending on several factors, including your starting weight, caloric deficit, and consistency with running and healthy eating habits. It’s important to be patient and focus on long-term, sustainable weight loss.

Q7. Can I lose weight by only running on a treadmill?

A7. Yes, running on a treadmill can be an effective way to lose weight. However, incorporating outdoor runs can provide variety and additional physical and mental benefits.

Q8. Should I run on an empty stomach?

A8. Running on an empty stomach can be beneficial for some individuals, especially for fat burning. However, listen to your body and fuel up with a light snack if needed before your run.

Q9. Can I lose weight by walking instead of running?

A9. Yes, walking can also help with weight loss. It may take longer to burn the same number of calories as running, but it is a low-impact exercise that can be sustainable and suitable for individuals with joint or mobility issues.

Q10. How can I stay motivated to run for weight loss?

A10. Find what motivates you, whether it’s signing up for a race, joining a running group, or setting goals. Additionally, mix up your running routine with different routes, music, or podcasts to keep things interesting.


Running can be an effective and enjoyable way to lose weight. By calculating your caloric deficit and adjusting your daily calorie intake, you can determine how much to run to achieve your weight loss goals. Remember to approach weight loss in a sustainable manner by combining running with a balanced diet and other forms of exercise. Stay consistent, be patient, and seek professional guidance if needed. Happy running!
