## How Many Calories Do You Burn a Day

Being health-conscious means that you need to know how many calories you burn in a day. Figuring out how much energy you expend any given day can help you determine how many calories you need to consume to either maintain a healthy weight, lose weight, or even gain lean muscle mass.

While you won’t burn exactly the same number of calories every day, you can calculate an estimation of your total daily energy expenditure (TDEE) based on your basal metabolic rate and your general level of activity.

### How to calculate TDEE

To calculate your TDEE, or the amount of energy you burn each day, you need to first determine your basal metabolic rate (BMR) using a BMR calculator. The most common formulas used for this equation are the Mifflin St Jeor^{[1]} and Harris Benedict^{[2]} equations.

By simply inputting your weight in kilograms, age, and gender, you can get a rough estimate of the number of calories that your body requires to function at rest.

After calculating your BMR, you then multiply this by an activity factor to establish your total daily energy expenditure. The activity factor is based on how much energy you use above your resting metabolic rate.

This chart provides a guide to determine what your individual activity factor is based on your lifestyle.

Level of Activity | Example | Activity Factor |
---|---|---|

Sedentary | Little to no exercise, such as a desk job with no additional physical activity | 1.2 |

Lightly Active | Light exercise 1-2 days/week | 1.375 |

Moderately Active | Moderate exercise 3-5 days/week | 1.55 |

Very Active | Hard exercise 6-7 days/week | 1.725 |

Extremely Active | Hard daily exercise and physical job or two times a day training | 1.9 |

The TDEE formula is BMR x your activity factor.

TDEE = BMR × Activity Factor

## How Many Calories Do You Burn Exercising

Using an activity factor is a good way to estimate your total daily energy expenditure on any given day. However, you can also calculate the number of calories burned during specific activities based on the type of exercise and the intensity.

The energy expended in any activity can be expressed as a standard number known as the metabolic equivalent of task, or MET.

When your muscles move, they require oxygen to produce energy. Activities that require more energy will burn more calories.

The metabolic equivalent of a task is the ratio of the metabolic rate during exercise in a given activity compared to the metabolic rate at rest.

One metabolic equivalent is the amount of oxygen consumed while sitting at rest, or 3.5 milliliters of oxygen per kilogram of body weight per minute.^{[3]}

METs are used to calculate how many calories are burned during exercise and physical activity.

### How to Calculate Calories Burned

To calculate calories burned during an activity, all you need to do is know the MET value of that activity, the amount of time spent doing the activity, and your current weight. This can then be used in the following formula to calculate the calories burned during that activity.

kcal = time [minutes] × ((MET × 3.5) × weight [kg] ÷ 200)

The Compendium of Physical Activities provides a comprehensive list of activities and their corresponding MET values.^{[4]} Some common activities and their MET values are provided in the table below.

Activity | MET Value |
---|---|

Sleeping | 0.95 |

Sitting quietly watching TV | 1.3 |

Walking, less than 2.0 mph | 2.0 |

yoga, Hatha | 2.5 |

Resistance (weight) training | 3.5 |

Bicycling, <10 mph | 4.0 |

Elliptical trainer, moderate effort | 5.0 |

Walking, 2.9 to 3.5 mph, uphill | 5.3 |

Jogging, general | 7.0 |

Circuit training, vigorous intensity | 8.0 |

Running, 6 mph (10 min/mile) | 9.8 |

Running, 8 mph (7.5 min/mile) | 11.8 |

Bicycling, 16-19 mph | 12.0 |

#### Sample calculations

##### Walking calories burned

For example, if you went for a slow walk for an hour, you could calculate the amount of calories burned during this activity by using the MET value above. First, you would need to divide your weight in pounds by 2.2, which will give you your weight in kilograms.

For a 180 pound person, weight in kilograms would be:

1802.2 = 81.8 kg

By inserting this number into the calories burned equation, you would have:

kcal = time [minutes] × ((MET × 3.5) × weight [kg] ÷ 200)

kcal = 60 minutes × ((2.0 × 3.5) × 81.8 kg ÷ 200)

kcal = 172 calories

On the other hand, if you were to walk uphill at a faster pace, the MET value would be closer to 5.3. In this instance, you would burn:

kcal = 60 minutes × ((5.3 × 3.5) × 81.8 kg ÷ 200)

kcal = 455 calories

##### Jogging calories burned

Jogging is slightly more intense and will therefore burn more calories. For the same person, jogging (MET of 7.0) for 60 minutes would burn:

kcal = 60 minutes × ((7.0 × 3.5) × 81.8 kg ÷ 200)

kcal = 601 calories

##### Running calories burned

Increasing the pace to a run at 7.5 minute miles requires more oxygen consumption and will expend even more energy. (MET of 11.8)

kcal = 60 minutes × ((11.8 × 3.5) × 81.8 kg ÷ 200)

kcal = 1,013 calories

As you can see, the more intense or vigorous the activity, the more oxygen is consumed and more energy is expended. This all corresponds to more calories burned. You can also burn more calories by simply increasing the time spent doing each activity.

## Using Calories Burned to Determine Calorie Intake

For people involved in fitness programs, figuring out how many calories they burn during exercise is a good way to gauge how many calories they should eat. On days that involve more intense physical activity, more calories will be burned.

Increasing physical activity is one way to aid with weight loss. Creating a calorie deficit of about 500 calories a day is a safe way to shed pounds. Since one pound is approximately 3,500 calories, this would result in losing about one pound a week.

However, it should be noted that this is only an estimate as there are a number of other factors that play a role in weight loss. Still, this provides a good guideline in a fitness program.

Studies have found that when exercise is sufficient to produce an energy deficit of 500–1,000 calories per day, substantial weight loss can occur.

Also, the addition of physical activity to healthy eating substantially increases the odds of long-term weight-loss maintenance.^{[5]}

While calculating your TDEE is a great way to estimate your daily calorie needs, using the MET equation may be even more helpful on days when you engage in more strenuous activity. This can give you an idea of how many calories you burn in each type of physical activity you participate in daily.
