Body Composition Analysis

How it Works

The InBody 270 Biolectrical Impedance Scale calculates a person's percentage of body fat. High body fat percentage is directly correlated with increased risk of obesity, cardiovascular disease, diabetes, and certain types of cancer.

For a more accurate result please follow the suggested instructions:

  • Hydrate the day before
  • Avoid alcohol or caffeine 24 hours prior to testing
  • Avoid exercising 6-12 hours prior to testing
  • Eat 3-4 hours prior to testing
  • Avoid using lotion or ointment on your hands and feet
  • Try to drink 4 cups of water before your appointment
  • Use the bathroom prior to testing
  • If you will be menstruating during the time you scheduled your appointment, the results may not be very accurate
  • If possible, come to your appointment in activewear clothing (you will be asked to remove shoes, socks, jewelry and belts)

Bioelectrical impedance is not recommended for those who have medical devices or think they are pregnant.

The Body Composition Analysis is conducted by a trained peer health educator and requires you to stand barefoot (in light clothing) on a scale. This a 15-20 minute appointment. 

You will receive a computer generated analysis with the following information: body weight, body mass index (BMI), percentage of body fat, calculated basal metabolic rate (BMR), fat mass, fat-free mass, and total body water. 

NOTE:  Registered UCSD students receive one FREE body comp per academic quarter.

You can make an appointment with the Registered Dietitian for any follow-up concerns you may have by calling (858) 822-5926.
