Test a portable device that measures your resting metabolism weekly

Recruiting

What is this trial?

This research study is testing a portable device called Breezing that measures your resting metabolic rate—essentially how many calories your body burns when you're at rest. Researchers want to see if this handheld device works reliably and if people are willing to use it regularly over six weeks. The study will compare measurements from the Breezing device with a larger, standard machine to make sure both give similar results.

Currently, measuring resting metabolic rate requires expensive equipment and trips to a clinic. If this portable device works well, it could make it much easier for people managing their weight or metabolism to track this important health marker at home.

Do you qualify?

You likely qualify if…

you are between 19 and 65 years old
you can read, understand, and speak English fluently
you exercise less than 300 minutes per week at moderate intensity
you live within one hour of the University of British Columbia Okanagan campus
you have access to a smartphone or tablet with Bluetooth and WiFi
you are willing to fast (no food or drinks except water) for 12 hours before each study visit

You likely don't qualify if…

you have cardiovascular disease, diabetes, cancer, thyroid disease, or HIV/hepatitis
you have uncontrolled high blood pressure, high cholesterol, sleep disorders, or severe depression
you are currently taking medications that affect metabolism or sleep, or started new medications in the past two weeks
you have a history of weight loss surgery, eating disorders, or have lost significant weight recently (more than 5 kg in the past year)
you work night shifts, travel across time zones frequently, or use tobacco or nicotine products

What participation looks like

You would attend two in-person visits at the university (each lasting about 3–3.5 hours): one at the start and one six to eight weeks later. Between visits, you would use the Breezing device on your own smartphone once per week for six weeks, fasting for 12 hours beforehand. At both visits, you'll have your metabolism measured with two different devices, answer health questionnaires, wear an activity monitor, and keep a three-day food diary. At the second visit, you'll also have a body composition scan and answer questions about your experience using the device.
