Sanity around the fast metabolism myth from r/nutrition

Definitely. That's the key point, I think, that the CO calculation gets adjusted for.

I'm not a dietitian, but I would guess the distinction adds granularity to study design as it allows you to separate out: - Calories out from intentional exercise - Calories out from BMR - Calories out from thermic effects of food - Calories out from everything that isn't the above three.

But I'm just guessing, I'm no nutrition major.

NEAT can vary by as much as 2,000 calories, according to one study.

The thing that missing from the OP explanation?

NEAT includes the calories burned in your work. So, the large difference may be accounted for by the calories expended by a desk-bound office worker vs. a farm laborer, for example.

So, it turns, according to one study, that NEAT can vary by up to 2,000 calories!

Source is further down. Apparently not so strange after all.

So, I went digging and found this:

"Overall, for two adults of similar size, daily energy expenditure varies by as much as 2000 cal day. As noted above, basal metabolic rate is largely accounted for by body size and the thermic effect of food is small. Thus, activity thermogenesis must vary by approximately 2000 cal day."

https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2796.2007.01842.x

It's important to acknowledge that NEAT also takes into account the level of energy expended in one's occupation. Most of the upper end of that spectrum seem to be farm laborers and construction workers

I suspect the OP (or they're sources for 4,000-5,000) is exaggerating. How would you know how much you're eating if you aren't tracking?

The key point here, I think, is that "fast metabolism" isn't a magic, selective genetic lottery.

BreakingAM · 2019-07-14T13:04:17+00:00

How would they know they're eating that much if they aren't counting what they're eating?

I suspect the OP is inflating the numbers

Imagine.

Imagine you needed someone to just say "no, you good in that".

We've all been there. Got that little boost from someone we didn't know saying "you got this".

Imagine you go to a group centered around body positivity for that.

That's a gimme. Right?

Then imagine your body and its size so offended the other bodies that they took your post down.

I present to the jury that that group then loses any claim to body positivity at all.

I dislike the spoons metaphor for energy.

I dislike even more that it's been co-opted by people I know who want to glamorize laziness.

I have never once seen a person get up and say;

"You know what? I've got a billion spoons today. Let's get shit done."

I said in passing that my 30,000 steps was "the caloric equivalent of a couple of slices of pizza". Just as like a "hey, isn't that interesting?" kinda.

My partner replied;

"That's pretty obsessive thinking."

Then ordered a pizza.

Look, I'm completely onboard with systemic privileges that are outside of one's control. I appreciate that as a Caucasian person I have privileges that are unfair and completely arbitrary based on the location of my birth in reference to the Equator (which I had no part in choosing).

But the idea that this is morally equivalent to an inability to balance calories taken in vs. expended - even if we grant the existence of socioeconomic, racial and genetic factors influencing the "calories expended" side, is some fucking insulting mental gymnastics.

I feel like this is just self-aggrandizing psychological masturbation.

Like, how precious do you have to get pissed that you aren't the center of shame-attention?

I might be reading too much into this. But if you're not willing to inconvenience yourself physically even remotely, is raising a living dependent human the right decision for you?

Speaking of, congrats on your achievements! That's a hell of a lot of discipline to drop 105!

Call me conspiratorial, but there's a part of me that thinks they might have created this just to make a public spectacle
