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.

Do alternatives to metabolism measurements actually work?

Are there other ways to know metabolism without measuring it?

Alternatives to Metabolism Tracking

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.

Chili Peppers and Metabolism

What other foods might increase metabolic rate? With the Breezing Tracker, the possibilities of discovery are endless.

Why Calorie Calculators DON’T Work

Not knowing your true resting metabolic rate can sabotage your weight loss efforts. Our newest video shows why calorie burn estimates from activity trackers, BMI, and other 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.
