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.

MyFitnessPal, Striiv Play, and Breezing Metabolism Tracking
Breezing’s study has just been published by the Global Journal of Obesity, Diabetes and Metabolic Syndrome. Our study, “Study of the Effect of Mobile Indirect Calorimeter on Weight Management” takes a closer look at calorie-counting, step-counting, and REE-counting.

Metabolism during Pregnancy: What Happens?
Metabolism changes greatly during pregnancy, and the way it changes can be different for each woman. Despite an increased need for calories, excessive gestational weight gain still affects many women, contributing to adverse maternal and child health outcomes. Extensive research has shown that real-time tracking of health parameters may improve prenatal health.
To better understand how pregnancy and metabolism are related, the Breezing Metabolism Team is working with The Human Placenta Project, a collaborative research effort launched by the NICHD to study the role of the placenta in health and disease.
(The.pdf version of this presentation is available for download here.)
Looking at three pregnancy cases, the results showed that REE during pregnancy can increase, stay the same, or even decrease. In the first case, REE increased during the second trimester and remained relatively stable through delivery. In the second case, REE stayed the same throughout pregnancy. In the third case, REE decreased with nausea and remained low later in pregnancy.
These results show that REE is unique for each woman, and it is a complex variable that depends on a number of different factors. “Calculating” REE is no different from estimating it. And, as studies have shown, these estimates can be very wrong. When considering the health of both the mother and the child, it’s more important than ever to measure and track metabolism, not just “calculate” a number.
Success Story: Dennis
We love to hear about the experiences of our Breezing users. This is Dennis’s inspiring success story, in his own words.
“My name is Dennis Bell. I am 67 years old in excellent physical condition and health but not too many years ago I couldn’t say that.
I remember returning to my hometown of Knoxville Tennessee over 4 years ago after spending almost 3 years in Washington State on my last consulting engineer assignment before retiring at age 62. Although I was elated to return to my hometown, I had let my weight get out of hand. I weighed 289 lbs.
