For many, fitness trackers have become indispensable tools for monitoring how many calories they’ve burned in a day. But for those living with obesity, who are known to exhibit differences in walking gait, speed, energy burned and more, these devices often inaccurately measure activity—until now.

Scientists at Northwestern University have developed a new algorithm that enables smartwatches to more accurately monitor the calories burned by people with obesity during various physical activities.

The findings were published in Scientific Reports. The study is titled, “Developing and comparing a new BMI inclusive energy burn algorithm on wrist-worn wearables.”

The technology bridges a critical gap in fitness technology, said Nabil Alshurafa, whose Northwestern lab, HABits Lab, created and tested the open-source, dominant-wrist algorithm specifically tuned for people with obesity. It is transparent, rigorously testable and ready for other researchers to build upon. Their next step is to deploy an activity-monitoring app later this year that will be available for both iOS and Android use.

“People with obesity could gain major health insights from activity trackers, but most current devices miss the mark,” said Alshurafa, associate professor of behavioral medicine at Northwestern University Feinberg School of Medicine.

Current activity-monitoring algorithms that fitness trackers use were built for people without obesity. Hip-worn trackers often misread energy burn because of gait changes and device tilt in people with higher body weight, Alshurafa said. And lastly, wrist-worn models promise better comfort, adherence and accuracy across body types, but no one has rigorously tested or calibrated them for this group, he said.

“Without a validated algorithm for wrist devices, we’re still in the dark about exactly how much activity and energy people with obesity really get each day—slowing our ability to tailor interventions and improve health outcomes,” said Alshurafa, whose team tested his lab’s algorithm against 11 state-of-the-art algorithms designed by researchers using research-grade devices and used wearable cameras to catch every moment when wrist sensors missed the mark on calorie burn.

The exercise class that motivated the research

Alshurafa was motivated to create the algorithm after attending an exercise class with his mother-in-law who has obesity.

“She worked harder than anyone else, yet when we glanced at the leaderboard, her numbers barely registered,” Alshurafa said. “That moment hit me: fitness shouldn’t feel like a trap for the people who need it most.”

By using data from commercial fitness trackers, the new model rivals gold-standard methods of measuring energy burn and can estimate how much energy someone with obesity is using every minute, achieving over 95% accuracy in real-world situations. This advancement makes it easier for more people with obesity to track their daily activities and energy use, Alshurafa said.

How the study measured energy burn

In one group, 27 study participants wore a fitness tracker and metabolic cart—a mask that measures the volume of oxygen the wearer inhales and the volume of carbon dioxide the wearer exhales to calculate their energy burn (in kilocalories/kCals) and resting metabolic rate. The study participants went through a set of physical activities to measure their energy burn during each task. The scientists then looked at the fitness tracker results to see how they compared to the metabolic cart results.

In another group, 25 study participants wore a fitness tracker and body camera while just living their lives. The body camera allowed the scientists to visually confirm when the algorithm over- or under-estimated kCals.

At times, Alshurafa said he would challenge study participants to do as many pushups as they could in five minutes.

“Many couldn’t drop to the floor, but each one crushed wall-pushups, their arms shaking with effort,” he said. “We celebrate ‘standard’ workouts as the ultimate test, but those standards leave out so many people. These experiences showed me we must rethink how gyms, trackers and exercise programs measure success—so no one’s hard work goes unseen.”

Other Northwestern authors include lead author Boyang Wei, and Christopher Romano and Bonnie Nolan. This work was also done in collaboration with Mahdi Pedram and Whitney A. Morelli, formerly of Northwestern.

Garmin has announced a new sleep-tracking band that can be strapped to your upper arm, which could make it more comfortable to wear overnight. The Index Sleep Monitor tracks sleep stages, heart rate, and even your breathing to create a “comprehensive view of overall fitness and recovery,” with a personalized sleep score delivered every morning so you know how well you slept, according to Garmin.

The Index Sleep Monitor is now available through Garmin’s online store in S-M and L-XL sizes for $169.99. The tracking is handled by a small, removable electronic module that features motion sensors and an optical heart rate sensor that Garmin says will run for up to seven days between charges.

In addition to tracking your light, deep, and REM sleep stages throughout the night, the Index can also measure your respiration rates, and, when paired with blood oxygen saturation measurements (a feature not available in all countries) it can help you “better understand shifts in breathing patterns while sleeping.”

A thermometer monitors skin temperature, which can provide insights into how your environment is affecting your sleep while also flagging possible illnesses. Those temperature measurements also provide more insight into women’s health monitoring, including menstrual cycles, “improved period predictions,” and past ovulation estimates. However, Garmin says the Index is “not a medical device and is not intended for use in the diagnosis or monitoring of any medical condition.” The company also says it should not be used as a conception or birth control tool.

Other health-related metrics that are monitored and made available through the Garmin Connect mobile app include estimates on stress levels based on sleep patterns, a Body Battery measurement letting you know if you’re low on energy and need more rest. Heart rate variability (HRV), which is a measure of the varying times between heartbeats, can also be used to assess if your body is dealing with increased stress or fatigue helping you know if you need to address issues with your sleep.

These are all metrics that can be measured using Garmin’s other smart wearables and many smartwatches, but only if you’re wearing them every single night. For those who prefer to charge their watches at night so their battery is full every morning, the Index Sleep Monitor provides an alternative way to track sleep metrics that’s also free of distracting notifications. The Index Sleep Monitor does have vibration capabilities, but they’re instead used as part of a smart alarm feature that only tries to wake you during lighter sleep stages.
