Are smart scales accurate to 5% in measuring resting metabolic rate? My Omron says 1950 calories but I swear others can have much more junk food and alcohol.
Not even close. They probably take the estimated fat-free mass (which comes with huge error bars), run it through something like the Katch–McArdle/Cunningham formula, which has IIRC something on the order of a 200 kcal stddev.
Re others having much more junk food and alcohol: you don't see what they're eating when you're not around. I'm one of those "fast metabolism" people, but what that also tends to come with is a very responsive appetite: left to my devices I eat a lot less the day after a big meal.

> That is a lot, or about as much intraindividual variance (when dividing the mean by the standard deviation) as something like IQ.
Isn't iq an arbitrary scale? Does this make sense?
I need gwerns take on this
Sigh.. bro makes the classic mistake of using the physics terminology vs how people understand the terminology.
