I once received a lot of blowback for an Upshot article in which I showed (with evidence) that exercise is not the key to weight loss. Diet is. Many, many readers cannot wrap their head around the notion that adding physical activity, and therefore burning more calories, doesn't necessarily translate into results on the scale. Well, here we go again because some of those folks also believe that fitness devices - Fitbit, Vivosmart, Apple Watch - must be helpful in losing weight. Unfortunately, evidence doesn't support this belief either. That's the topic of this week's Healthcare Triage. This episode was adapted from a column I wrote for the Upshot.
