Apple Watch and Apple Health Data

FaunalFantasy

This year I have transitioned from fitbit to apple watch and I'm unsure if I am reading the data correctly. The Health app has a resting energy category and an active energy category. The resting energy, I assume, is BMR, while the active category is everything on top of that. So, if I were to add those two numbers together, I should get my TDEE, correct?

I've averaged 1,300 resting energy and 400 active energy since January 1, so my average TDEE should be the sum of those two figures, 1,700, correct?

In theory, the resting energy is a sedentary activity factor. The Active calories are anything that you do that is 3 METS or higher -- so your non-sedentary stuff.

But yes -- how you're calculating it is how you'd find your TDEE. To find your true RMR, though, divide the resting by 1.2.

I found that for me, the resting energy needed to be increased by 20 percent to get to a true TDEE between the two. (I had my RMR lab-tested, so had a baseline of where I needed to start adjusting from.)

@collectingblues So if I am understanding you correctly, the resting energy is slightly higher than your true RMR because it is assuming some sedentary activity, not simply catatonia. The active energy count kicks in when you are doing something that is 3 METS or higher than the resting energy.

Regardless, I should be getting a reasonable average TDEE by summing the two.

Correct.

Just to check this... you measured this over a 24 hour period?
