How is Metabolic Factor calculated?
First, we will use a machine to measure your Resting Metabolic Rate through a process calledindirect calorimetry. Then, that number is divided by your weight.

What does my number mean?
If your RMR is 2,000 and you weigh 200 pounds, your Metabolic Factor would be 10.0, meaning your body burns 10 calories for every pound that you weigh. Metabolic Factor is a measure of how efficient a body is with food. A person with a Metabolic Factor of 6.0 is much more efficient than a person with a 16.0. In times of famine, someone with a 6.0 may outlive the person with a 16.0 because of the greater efficiency with limited food. However, in times of plenty, the person with a 6.0 is much more likely to become obese. Here are the averages:

Obese             8.3
Overweight         10.6
Normal Weight     12.8

What is Metabolic Factor?
People are biologically wired to have certain traits, such as height or curly hair. Similarly, there is a predisposition to have a particular weight. Obesity is a complicated mix of biology and behaviors, but Metabolic Factor can tell you a natural weight for your unique body.

Research on Metabolic Factor published by Dr. Davis in peer-reviewed journals:
Archives of Medical and Biomedical Research
Obesity Surgery (in press)

Can I speed up my Metabolic Factor?
Although more research needs to be done, unfortunately it does not appear that Metabolic Factor can be increased. Research suggests that it does not change even after significant weight loss from bariatric surgery. In fact, Metabolic Factor seems to slow a bit as we age. 

How is Metabolic Factor used?
Metabolic Factor can be used to set weight loss goals. For example, people with a Metabolic Factor of 12.8 whose Body Mass Index is in the obese range are obese even though they are biologically predisposed to be a normal weight. This suggests the basis for their weight problem is primarily behavioral. Dr. Davis can help them adjust their lifestyle to get their weight in line with their biological makeup. For people whose Metabolic Factor is 8.3 but their Body Mass Index is in the overweight range, they are overweight even though their body wants them to be obese. These individuals are likely working hard to eat well and exercise to manage the body they were given. Body acceptance will be an important task for these people.
