Health Screenings and Assessments
Screening includes body fat percentage, lean mass percentage, and goal weight.
What is body composition?
Body composition is the proportion of fat, muscle, and bone making up the body. Body composition is usually expressed as a percent of body fat and lean body mass (bone, muscle, organ tissue, blood and everything else). For example, if you are 150 pounds and 10% fat, it means your body consists of 15 pounds of fat and 135 pounds of lean body mass (bone, muscle, organ tissue, blood and everything else).
Why measure body composition?
The test is used as a guide for determining ideal weight and for monitoring progress in a weight management program. Body weight alone provides little information with regard to the composition, or quality of an individual’s body weight.
How does electrode impedance body fat analysis work?
This test involves passing a small electric current through the body and measuring the resistance encountered. Lean body mass (bone, muscle, organ tissue, blood and everything else excluding fat) is a good conductor of electrical current allowing the electrical current to move through the body more easily whereas fat is not a good conductor of electrical current and therefore creates more resistance.
- Testing Method: Bioelectrical Impedance using ELG Metabolic Analyzer
- Results include % Body Fat, pounds of body fat, % Lean Mass and pounds of lean mass, goal weight, and basal metabolic rate (estimate of your calorie needs at rest). You will receive a body fat rating of Risky, Ultra Lean, Lean, Moderately Lean, or Excess Fat, depending on your body fat percentage.
- Length of test: 5 minutes
- Appointment length: 15 minutes
Resting Metabolic RateThis test will give you the exact measurements needed to succeed in weight loss or weight maintenance. The metabolic rate is used to calculate the target caloric zones. These zones will show you how to eat the maximum amount of food and still lose weight or maintain your current weight.
What is Resting Metabolic Rate (RMR)?
Resting Metabolic Rate is an estimate of the amount of calories your body uses at rest.
Why measure Resting Metabolic Rate?
By testing your RMR you will learn how your metabolism compares to an average person with the same age, height, weight, and gender as you. Whether you have a slow, normal, or fast metabolism, you will know how many calories it will take to maintain your current weight, lose weight safely, or gain weight.
What does the test involve?
In order to determine your resting metabolic rate, you need to fast for at least 4 hours and avoid exercise prior to the test. For 10 minutes, you will be asked to breathe exclusively into a metabolic machine while at rest. Once you have completed your 10 minute test, you will receive a thorough printout listing your calorie needs at rest, with lifestyle and activity, calorie burn during exercise, calories needed for weight maintenance and loss and an estimate of time that it will take for you to reach your target weight.
