How Accurate are Smart Watches?
Wearable devices have as much as 20% error when measuring heart rate, and caloric expenditure measurements can be off by as much as 100%. Most wearable fitness devices overestimate total sleep time and underestimate wakefulness after sleep onset.

Key Quotes
"Stop making weight loss your New Year's resolution, because that's why you continue to fail. If you really dial down on small, permanent lifestyle changes that you know are going to ultimately optimize your health at the end of 12 months, you're gonna have lost."
"The things that I think people overlook when they're looking to optimize their health, number one would be sleep. Sleep is absolutely most people's missing link. You know, I think that there's a set of people that are just not getting sleep at all. The quality of their sleep is poor. It's at epidemic proportions."
"I also know that there's some really good research around, I mean, if we take it back to nutrition just for a second. And overeating because when you don't get enough sleep, leptin and ghrelin, which are our hunger hormones, are impacted. And so we tend to eat more."
"And then I think that there's also the, um, the exercise piece. You know, we, we talked about that, that consistency piece. But I also think that, you know, people, they go all in on their, their exercise plan in January, and then they can't sustain it. They get burnt out. They, you know, they're sore. They're, you know, not seeing the progress that they want to see, and then they just throw in the towel."
"But I think that stress management is key. You know, we, we talked about, you know, managing our nutrition and managing our exercise, but if we're not managing our stress, it's going to impact everything else."
