How many calories burned equals 1 pound?

It’s a common goal for many people trying to lose weight: “I want to lose X pounds.” But what does it actually take to lose a pound of body fat? The answer lies in understanding the relationship between calories burned and weight loss.

The Basics of Calories and Weight Loss

At its core, weight loss boils down to a calorie deficit – you have to burn more calories than you consume. To lose one pound of fat, you need to have a calorie deficit of approximately 3,500 calories. This calorie deficit can be achieved either through diet, exercise, or a combination of both.

Here’s a quick overview of how calories relate to weight loss:

  • There are 3,500 calories in one pound of fat
  • To lose one pound, you need to burn 3,500 more calories than you consume
  • A calorie deficit of 500 calories per day = 1 pound lost per week (500 x 7 days = 3,500 calories)

So in simple terms, if you want to lose one pound of fat, you need to burn an extra 3,500 calories total, which can be broken down into a daily calorie deficit.

Calories Burned Through Exercise

Exercise is one of the main ways you can burn extra calories to create a deficit for weight loss. But how many calories does different types of exercise actually burn?

Here are estimates for calories burned per hour for a 155 pound person:

Exercise Calories Burned (Per Hour)
Walking (3.5 mph) 300
Jogging (5 mph) 570
Bicycling (leisurely) 290
Bicycling (vigorous) 590
Swimming (freestyle, moderate effort) 510
Aerobics 480
Elliptical trainer 365

As you can see, the number of calories burned varies widely depending on the exercise. Low-impact activities like walking and leisurely cycling burn 200-300 calories per hour. More intense exercises like running, vigorous cycling, and aerobics burn 500-600 calories per hour.

How Many Calories to Burn Per Day

If you create a 500 calorie per day deficit through exercise, you can lose about 1 pound per week. Here’s how many calories you would need to burn each day to lose 1 pound in a week:

  • Walking: 60-90 minutes per day
  • Jogging: 30-45 minutes per day
  • Bicycling: 60-90 minutes per day (moderate effort)
  • Aerobics: 45-60 minutes per day
  • Swimming: 45-60 minutes per day

For most people, a calorie deficit through exercise alone can be challenging to sustain in the long-term. Combining exercise with dietary changes is often more realistic for lasting weight loss.

Calories Burned Through Diet

In addition to exercise, you can create a calorie deficit through your diet and eating habits. Here are some estimates for calories burned from various dietary strategies:

  • Reducing 500 calories per day from your diet = 3,500 weekly deficit = 1 pound lost
  • Intermittent fasting (16 hours fasting/8 hours eating window) can burn 400-500 calories per day
  • Ketogenic diet may burn 200-400 calories more per day than a standard diet

As you can see, making simple reductions in your daily food intake and modifying your eating schedule or diet type can also lead to meaningful calorie deficits. Combining these dietary changes with exercise can accelerate weight loss.

Putting It All Together

To summarize, here are some key points on calories burned and weight loss:

  • A deficit of 3,500 calories = 1 pound lost
  • You can create a 500 daily calorie deficit through about 1 hour of moderate exercise daily
  • Dietary changes like calorie reduction, intermittent fasting, and keto can also burn 200-500 calories per day
  • For optimal weight loss, combine exercise with dietary changes to maximize calorie deficit

A Sample Plan

Here is a sample one-week plan to lose 1 pound by combining exercise and diet:

Day Exercise Diet Calorie Deficit
Monday 45 min jog (burns 500 calories) Reduce food by 200 calories 700 calories
Tuesday 60 min brisk walking (burns 300 calories) 16 hour fast (burns 400 calories) 700 calories
Wednesday 30 min swim (burns 300 calories) Reduce food by 200 calories 500 calories
Thursday 45 min elliptical (burns 325 calories) 16 hour fast (burns 400 calories) 725 calories
Friday 60 min cycling class (burns 500 calories) Reduce food by 200 calories 700 calories
Saturday Rest day 16 hour fast (burns 400 calories) 400 calories
Sunday 60 min aerobics class (burns 480 calories) Reduce food by 200 calories 680 calories
Total Weekly Deficit 4405 calories

As you can see from this example, creating a 500-700 calorie daily deficit through exercise and diet can lead to burning 3,500+ calories per week, which equals about 1 pound of fat lost.

Variables That Affect Calories Burned

It’s important to note that the actual number of calories burned through exercise and dietary changes can vary significantly based on individual factors like:

  • Body composition – People with more muscle mass tend to burn more calories than those with higher fat percentages
  • Fitness level – More fit individuals tend to burn more calories for the same exercise duration
  • Age and gender – Younger adults and men tend to burn more calories than older adults and women
  • Genetics – Some people inherenty have a faster or slower metabolism

Due to every person’s individual variances, the actual number of calories burned for you may be higher or lower than these general estimates. It’s best to use a calorie tracking app or heart rate tracker to get a more personalized view of your daily calorie burn through exercise and dietary changes.

Other Considerations for Weight Loss

While a calorie deficit is the key driver of weight loss, there are some other factors that can impact your progress including:

Macronutrient Balance

Getting the right balance of protein, carbs, and fat can help optimize body composition during weight loss and preserve metabolism:

  • Protein intake should be 0.5-1g per pound of bodyweight to preserve muscle mass
  • Carb intake less than 130g per day can help induce ketosis for fat-burning
  • Limiting added sugar and refined carbs can decrease fat storage hormones
  • Healthy fats should make up 25-30% of total calories

Strength Training

Including 2-3 strength workouts per week can help prevent muscle loss and increase metabolic rate:

  • Lifting weights triggers muscle protein synthesis
  • Building muscle increases resting metabolic rate
  • Total calorie burn will be higher with more muscle mass

Cardiovascular Exercise

Getting in 150-300 minutes of cardio exercise per week provides many benefits:

  • Burns additional body fat
  • Improves cardiovascular fitness
  • Increases endurance
  • Boosts metabolism through EPOC (excess post-exercise oxygen consumption)

Sleep and Stress Management

Prioritizing sleep and managing stress can also optimize weight loss results:

  • 7-9 hours of sleep per night supports fat burning hormones
  • Chronic stress increases cortisol which can increase fat storage
  • Relaxation, yoga, meditation helps lower stress and cortisol


In summary, burning approximately 3,500 calories through diet and exercise leads to about 1 pound of fat loss. There are many ways to create this weekly deficit through combinations of diet, aerobic exercise, strength training, and lifestyle factors. Tracking your calorie burn along with macro intake, body composition, and other metrics can help optimize your rate of weight loss while preserving muscle mass.

Sustainable weight loss requires patience and consistency with both exercise and nutrition over the long-term. But understanding the relationship between calories burned and pounds lost can give you an informed foundation for setting effective weight loss goals and plans.
