Daily Energy Expenditure Calculator

Firstly - If you are considering starting a new fitness regime, it's always best to seek your doctors advice first. This calculator doesn't know your medical history, only you and your doctor knows that, so check with your doc before starting.
You can use the Daily Energy Expenditure Calculator below to find out how many calories you burn in a day.

Knowing how many calories you burn in a day is the first step to weight loss, and is also essential to maintain your current weight if that's what you want to do.

Everyone burns a different amount of calories in a day, thanks to differences like age and gender, so a one size-fits-all number won’t be accurate for everybody. This calculator will calculate how much energy you expend in a day – not how much the average person burns.

The Daily Energy Expenditure Calculator requires the following inputs -

1.  Weight (lbs.)

2.  Height (in.)

3.  Age

4.  Sex

All of these variables are important. After you input all of the variables, the calculator will calculate the energy you burn over the course of a day.

Weight - Weight is one of the primary determinants of your metabolism. The more you weigh, the more calories you will burn. This is true if you are working out or just sitting at the computer. This health calculator is set up to use imperial measurements, so you must input your weight in pounds.

Height - The more surface area your body has, the more energy you will expend in a day. This means that taller people naturally burn more calories than shorter people. Your height must be in inches when you put it into the calculator. If you are 5’6” tall, for example, you height input will be 66 inches.

Age - Metabolism is strongly determined by age. When we are young we burn up a lot of energy. As we get older, our metabolism gradually slows down. The metabolic peak is usually around age 20. Beyond that, our BMR goes down by approximately 2% every 10 years.

Sex - Your sex also plays an important role in determining your metabolic rate. Sorry ladies, but us men naturally burn more energy than women do. This is because we have less body fat and more muscle mass.

Your Daily Energy Expenditure - After you have entered all of the variables into the calculator you will find out your daily energy expenditure. But what does this number mean?

Your Basal Metabolic Rate is how much energy you have to expend every single day just to stay alive. It is how much energy you need just to keep going. The formulas only consider a person at rest, so it does not take into account calories burned as you do things during the day. Basically, your BMR is how many calories you burn if you stay in bed and watch TV or sit in front of a computer screen all day. Exercise and other activities will increase the amount of calories you burn. BMR is often used as a starting point when someone is designing a weight-loss or maintenance programme.

Variations - There are some variations which just can't be accounted for by the calculator. Genetics can often play a role in determining a persons BMR and some people naturally have a very high or very low metabolism. Your environment can also play a role. Those who live in colder climates tend to have higher BMRs. Regular exercise will also increase your BMR.
