how many calories in a day per personCalories are simply energy that is burned by your body to sustain regular body movement and functions.  This energy comes to us in the form of food broken down into proteins, carbohydrates and fats.  So what is the amount of calories a person burns in a day?  Well, that is dependent upon several factors such as your gender, age, height, weight and activity level.  Let’s take a look at these factors individually. You can also briefly visit our how many calories to lose weight page to learn more about calculating how many calories you need to burn to lose weight or go here to immediately calculate it.

Men vs. Women

Gender plays a huge role in calorie burning.  Men are blessed with much more natural lean mass and less body fat.  As a result, they burn calories at a much faster rate than women.  The outcome is that it is much easier for men to lose weight than their female counterparts.

The Importance of Age

Age becomes a factor in calorie burning because the human body is designed to slow down its metabolism (or the rate at which you burn calories at rest)  as it ages.  Therefore, the older you are, the fewer calories you will be burning while doing normal activities.  This is also why older people have more difficulty losing weight(especially to lose weight fast) than individuals in their teens and twenties.

Height and Weight

Height and weight are also important. The bigger you are, the more calories you will be burning to keep your digestive system and brain working at full capacity.  This explains why when an overweight person adds vigorous exercise to a normally sedentary life; they experience very quick and massive weight loss.

The Importance of Exercising

Activity level may be the most important factor when assessing how many calories you burn during the day.  Exercise forces the body to burn calories to reduce body temperature and to recover from strain.  It also acts to permanently speed up your metabolism.  However, the best form of exercise for burning calories is actually weight training.  Now, obviously running three miles will burn more calories than an hour of weightlifting.  Yet, weightlifting builds lean mass or muscle.  Lean mass burns calories at a much higher rate than fat.  So in essence, the more muscular you are, the faster you are burning calories at rest. Another good tip is to exercise twice a day, this will give you maximum weight loss results. A good diet to follow to speed up your metabolism is the 6 meals a day diet.

Don’t Starve Yourself

It is also important to keep in mind that fasting or starving to lose weight has the exact opposite effect of burning calories. You do not want your body to enter starvation mode.  In this case, the body senses it is starving and shuts down its calorie burning capability to the lowest level possible.  The solution is to eat very small meals constantly to keep your body digesting throughout the day which also raises your metabolism.
