The Science Behind Measuring Metabolism vs Calculating Metabolism
A new study published by Dr. Yue Deng (ASU School of Engineering) and Dr. Barbara Scott (University of Nevada School of Medicine) compares resting metabolic rates calculated using predictive equations to metabolic rates measured using an indirect calorimeter.
The difference between the calculated and measured results was shown to be as high as 900 kCal/day. To put that into perspective, 900 kcal/day difference could explain a weight gain of 80 pounds in a year if the resting metabolic rate is not appropriately addressed with a measurement.

Breezing Invited to Pitch at MedCity Invest
Obesity Solutions: Breezing Metabolism
How does metabolism affect your daily lifestyle decisions? New research shows that the breath analysis used in the Breezing Metabolism Tracker can help demonstrate metabolic progress, reflecting changes in diet, nutrition, and exercise. In other words, metabolism tracking shows us a revolutionary new way to think about health and fitness measurement.
Breezing Wins Fall 2018 AIC
Breezing Announced as AIC Finalist
The Arizona Commerce Authority (ACA) has just announced Breezing as one of twenty finalists in the Fall 2018 round of the Arizona Innovation Challenge, a bi-annual business plan competition for promising early-stage companies in high-growth industries.
“The technologies being developed by each of our 20 finalists is truly impressive, and we congratulate them on being named finalists,” said Sandra Watson, President & CEO of the Arizona Commerce Authority. “I wish all of them the very best of luck in the next round of the competition and look forward to watching their final pitches!”
Breezing Announces Andrew Steele as Chief Executive Office
Tempe, AZ, September 10, 2018 – Breezing today announced the appointment of Andrew Steele as Chief Executive Officer, effective on August 16th, 2018. Steele is a Silicon Valley veteran and brings over two decades of success in leadership roles at high growth technology companies.
“This is exactly the right time to bring a seasoned CEO into the company, and we are thrilled to have Andrew join us,” said Dr. NJ Tao, Breezing’s co-founder and Chief Science Officer. “We have made incredible progress since spinning out Arizona State University in 2011. Our product is already in use by thousands of people around the world, and we have received multiple patents recognizing our innovative work. We have conducted successful clinical trials with partners including Mayo Clinic, University of Arizona and Penn State University that have proven the efficacy of Breezing’s metabolic tracking technology for improving the outcomes of clinical obesity programs, diabetes management and pre-natal care, as well as reinforcing positive behavioral changes related to individual health, fitness and weight management goals,” said Dr. Tao. “Andrew has already proven his ability to create significant growth and shareholder value, and so as we transition from a focus on product development and market validation to a full commercial launch of our product, he is the ideal person to lead the continued success of the company.”
Do alternatives to metabolism measurements actually work?
Are there other ways to know metabolism without measuring it?
Dr. Sachiko St. Jeor, co-creator of the Mifflin St. Jeor calculator, reveals differences between a calculation and an actual measurement can be as much as hundreds of calories. Check out the poster here.
Meanwhile, a team of researchers, led by Banner Health’s Dr. Soto, demonstrate the major pitfalls of using a body composition analyzer to estimate metabolism for patients undergoing bariatric surgery. You can read the details here.
Eating chili peppers might increase your metabolic rate
Using the Breezing Tracker, a team of researchers were able to determine a positive correlation between capsaicinoids (an active component found in chili peppers) and resting metabolic rate. You can read the full study here.
What other foods might increase metabolic rate? With the Breezing Tracker, the possibilities of discovery are endless.
Why Calorie Calculators DON’T Work
How accurate are activity trackers, really?
According to researchers at Stanford University, most fitness trackers can’t be relied on to accurately track number of calories burned. Here’s what happened:
Apple Watch, Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn and Samsung Gear S2 were tested in a group of 60 people. The results showed that measuring heart rate had an error rate of less than 5% on 6 of the devices, while none of the devices were accurate when measuring energy expenditure. The most accurate device was incorrect by 27% on average while the least accurate was off by 93%.
Thirty-one women and 29 men volunteered to help test the accuracy of the devices. Each volunteer wore the 7 devices while walking or running on treadmills or while using stationary bikes. Their heart rates were measured using a medical-grade electrocardiograph and the metabolic rate was measured with an instrument that measured the oxygen and carbon dioxide in their breath. The researchers then compared the results from the actual medical devices to the fitness trackers.
“The heart rate measurements performed far better than we expected,” said Ashley. “But the energy expenditure measures were way off the mark. The magnitude of just how bad they were surprised me.”
Since each device uses its own custom algorithm for calculating energy expenditure, the researchers aren’t sure why the measurements are so wrong.
“All we can do is see how the devices perform against the gold-standard clinical measures,” Shcherbina said. “My take on this is that it’s very hard to train an algorithm that would be accurate across a wide variety of people because energy expenditure is variable based on someone’s fitness level, height and weight, etc.”
And that’s why any activity tracker that claims to tell you “resting calorie burn” or “metabolic rate” is just plain wrong. Luckily, Breezing’s Calorie Corrector is here to correct the numbers generated by activity trackers, bridging the gap between activity trackers’ estimates and true metabolic rate.
