Body Composition Assessment
BodPod: Body Composition
Scales provide you with your weight, but that is not the entire picture. Body composition analysis with an air displacement plethysmography device (BodPod) is a precise method to determine how much of your body is fat mass versus lean mass (muscle, bone and organs). It is nearly as accurate as a dual-energy x-ray absorptiometry (DEXA) test without the exposure to radiation and increased cost. Your unique body composition offers insight into your overall health, including disease risk, physical function, and athletic performance. This easy, non-invasive test will generate results that tell you your body-fat percentage and amount of fat-free mass. We pair this data with additional measures to determine your body-fat distribution and risk of chronic disease.
Establishing a baseline body composition before you embark on a health and wellness journey will allow you to track your changes and progress. We recommend follow up assessments every 6-10 weeks, depending on your goals, as a powerful tool to understand the impact of your lifestyle changes on your proportion of fat mass to fat-free mass.
Includes:
- 30-minute body composition assessment and body shape measures + post-test report
Metabolic Assessments
Resting Metabolic Rate and Resting Energy Expenditure
One of our signature tests, the Resting Metabolic Rate (RMR) assessment, measures your body’s resting rate of oxygen consumption. This highly accurate procedure allows us to determine the number of calories that your body burns over the course of the day to function normally, without accounting for any additional movement and activity. The data from this RMR allows us to generate three critical data points: your resting metabolic rate, your resting energy expenditure, and your respiratory exchange rate.
These 3 highly individual data points allow us to determine 3 powerful personal metrics:
- How your metabolic rate compares to the general population
- The exact number of calories that you are burning at rest in a day
- What type of fuel your body uses while resting (stored fat or stored carbohydrates)
Whether your goal is to lose, gain, or maintain your weight, this information is a critical part of designing and personalizing a weight management program.
Includes:
- One-Hour: RMR Assessment + Post-Test Counseling Session
FatMax Protocol: Personalized exercise to maximize fat-burning
Exercise recommendations are over-generalized. What works well for one person may not be effective for another. Our FatMax protocol allows us to create a personalized exercise plan, designed around your own metabolic measurements, to maximize the effectiveness of your exercise.
The FatMax test is a multi-stage bicycle exercise test that measures the ability of your body to burn fat at different exercise intensities. During this test, we capture a wide range of data including heart rate, oxygen consumption, rate of fat and carbohydrate burning, and total calorie burn at each intensity. With this data we will pinpoint the exercise intensity at which you are burning fat at the highest rate (your personal FatMax). We then develop a strategic exercise prescription, based on your personal data, to:
- Offer specific insights on your personal exercise goals and determine the ideal exercise prescription for you to achieve your goals
- Help you achieve your fitness and/or weight management goals
Includes:
- One-Hour: FatMax Assessment + Post-Test Counseling Session
- Biweekly Check-Ins with Registered Dietitian/Exercise Physiologist throughout lifestyle program period
24-Hour Metabolic Chamber: Total Energy Expenditure
Our metabolic chamber is a gold-standard research environment disguised as a comfortable windowed living room. The chamber allows us to capture your energy use in a “free-living” environment. Recording minute-by-minute energy expenditure and breathing rate over the course of a 24-hour period creates a comprehensive picture of your individualized caloric burn during rest, sleeping, exercise, eating, and performing any activities of daily life. We can then analyze how your individual data compares to that of the general population.
The 24-hour schedule will be planned in partnership with you to mimic your day-to-day life as closely as possible and help you achieve your goals. We can incorporate sessions of different types and intensities of workouts, allowing us to determine which exercise routine optimizes your calorie burn and fuel utilization, to design the most effective workout for you.
Using this data, we provide insights on the ideal way to achieve your personal goals and equip you with the knowledge and tools you need to make strategic lifestyle changes—or just better understand the mechanisms that fuel your body.
*We also offer a validated 3-hour chamber assessment that predicts 24-hour energy expenditure if you only want to know the total amount of calories you burn in a typical day
Includes:
- 24-Hour Assessment and Counseling Session
- Biweekly check-ins with Registered Dietitian/Exercise Physiologist throughout lifestyle program period
Fitness Assessments
Cardiorespiratory Fitness: VO2max
The gold standard measure of cardiorespiratory fitness, VO2max measures the ability of the heart, lungs, and blood to deliver oxygen to your muscles, and the ability of your muscles to use that oxygen during exercise. This test offers insight into overall health status and chronic disease risk, as well as your degree of cardiorespiratory fitness compared to the general population.
This protocol can be conducted on a stationary bicycle or a treadmill and will generate data that allows us to evaluate your overall cardiovascular fitness level and exercise performance. We then use this personal data to:
- Characterize your cardiovascular health status and chronic disease risk
- Prescribe an individualized exercise program designed for your health goals
We also offer submaximal VO2max testing for individuals with a lesser or no exercise background. This validated test estimates VO2max based on submaximal work rates and predicts cardiorespiratory response to exercise. Submaximal testing is appropriate for individuals who cannot perform maximal exercise due to health limitations.
Includes:
- One-hour assessment and post-test counseling session
Sport-Specific Testing: Exercise Energy Expenditure and Sports Nutrition
This hands-on, customizable protocol is designed to answer your most-pressing questions on fueling your body for your favorite sport. Prior to the session, we will have a discussion on your current routine and your upcoming goals. Based on this information, we will create a completely individualized sport-specific exercise testing protocol, designed to answer your questions on fueling for peak performance. With the data gathered from the protocol, we will provide you with a personalized plan including:
- An exercise plan tailored to your metabolic results and performance goals
- Nutrition guidelines that are most appropriate for your individual performance goals
Includes:
- Custom exercise protocol and pre- and post-test counseling session
- Biweekly check-ins with Registered Dietitian/Exercise Physiologist throughout lifestyle program period
Nutrition and Lifestyle Counseling
Data gathered from your metabolic tests is just one aspect of personalizing an approach to achieve your health goals. Our team of registered dietitians and certified exercise physiologists is available to help you take the next step with strategic, individualized diet and exercise analyses and prescriptions.
