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.

Researchers have developed a simple yet powerful method that has the potential to reduce the use of expensive bacterial cultures by up to 80%, while also extending shelf life.
