Role of Non-Activity Thermogenesis in Resistance to Fat Gain
|
Nice article Lyle,
I have a question about NEAT though. If I understand correctly, NEAT is actually caused by extra movement correct, not just the burning of extra calories for no reason? So, just for illustrative purposes, if a person realized that subconciously he was moving more (neat) and purposely fought the urge, would he now be taking away all his NEAT? So if two people sat side by side, one person having very low NEAT and the other very high but both sat on the couch perfectly still (one person having to consiously do so) the person with high NEAT would lose his advantage right? |
Yes. NEAT is calories burned due to the moving around/fidgeting/etc. If you somehow consciously prevented that, you'd lose the benefit.

Interesting stuff. Thanks Lyle.
I took the liberty to look up the paper. If I'm reading it right, 8 out of the 12 male subjects got a boost of activity that generated 400 calories or more a day. That's pretty surprising and intriguing. I was curious about this because I wasn’t sure if most got a boost of 100-200 (for example) and then there was one freak at nearly 700. It looks like there were actually two individuals over 600 and 3 others fairly close to 600. 1. Considering how many calories are burned in a typical hour of formal exercise, I think 400+ is a lot of activity via NEAT. 2. I'm sort of surprised that 400+ seems to be somewhat common among the males (although maybe this is skewed because they only chose fairly lean subjects to begin with) 3. Makes total sense why some can make muscular gains on a 500 cal surplus and others don't (for example). Eh, just some of my thoughts. Very cool paper and article. |
I've read, I think from you, that a drop in metabolism of 10% while dieting would be a big deal. I assume this is RMR.
I wonder if "all-in" daily metabolic change has been expressed as a percentage anywhere. For instance, these guys, on overfeeding, if their starting diet was like 2000-2500 calories, may have had increases in daily burn of 33% to nearly 50% once all sources (RMR, TEF, NEAT) are factored in. |

That's a 20% total increase. |

Lyle do you have any idea what if any the affect the macro nutrient ratios would play in regards to NEAT when running 1000 calories over maintenance levels?
IE how would less fat and a higher percentage of protein and/or carbs affect things? |
Overkill: what chart are you looking at, I have the paper here in front of me and see no indivdiual data.
Incindium: To my knowledge nobody has examined the impact of different macros on this. |
