Resting Metabolic Rate

It is no secret that the best method to lose or gain weight is through proper diet and exercise. 

Any change in body weight is the result of a calorie imbalance between energy intake and energy expenditure.  When people gain weight it is because they are in a positive energy balance.  That means that they are taking in more calories than they are expending.  To lose fat our bodies need to be in a negative energy balance (expending more calories than you are taking in) for an extended period of time.  When a state of energy balance is achieved our weight remains constant.

Now the question becomes…

How do you know how many calories to intake and expend???

This is where resting metabolic rate (RMR) comes into play

Resting Metabolic Rate (RMR) Assessment

Your resting metabolic rate is the key to successful weight management.      

It can be defined as the amount of energy your body uses at rest.                      

Why is this important?

If you can determine your resting metabolic rate you can then determine how many calories you can eat in a day to maintain, lose, or gain weight.  The key is finding the actual number.  If you can accurately determine the amount of energy your body needs to function each day, you can determine the number of calories your body requires.  Resting metabolism makes up the largest part of the expenditure portion of the energy equation.  It typically constitutes 60-75% of the total energy usage in healthy individual.

The Harris Benedict equation which is typically what is used to estimate RMR has a 1000-calorie margin of error

Gary Foster, University of Pennsylvania, 1988.

The New Leaf RMR assessment measures gas exchange (O2 & CO2) through inhalation and exhalation at rest. 

Using a lifestyle correction factor a BodyFit trainer can then determine the amount of calories that you burn which can be used to identify your individual caloric intake needs per day.
