Learn moreKnowledge is power, the saying goes, so you may be tempted to use wearables to track your health data in the hopes of preventing or managing an illness or hitting certain fitness goals.
Plus, it's important to take the data, which might not be entirely accurate, with a pinch of salt, Probert said.
That doesn't mean the best fitness trackers aren't helpful, it just means you shouldn't take their data as gospel.
Fitness trackers can't know our metabolic rates and how much muscle we have compared to body fat, which affects our energy expenditure.
And, Probert cautioned, it's important not to stop listening to your body and checking in with how you feel when using such devices.
