«It looks like I was wrong about low-carb diets.
Specifically, I've always said low-carb diets do not affect energy expenditure. There used to be concern that low carb intakes tanked your thyroid and thyroid hormone metabolism does indeed change on lower carb intakes, but this does not affect total net energy expenditure.
However, a recent meta-analysis by Ludwig et al. (updated from their previous one) finds low-carb diets result in a higher total energy expenditure than high-carb diets in longer-duration studies, whereas in shorter-duration studies, high-carb diets win out slightly.
"Among 23 shorter trials, total energy expenditure was reduced on lower-carbohydrate diets (−50.0 kcal/d) [...]. Among 6 longer trials, total energy expenditure was increased on low-carbohydrate diets (135.4 kcal/d) [...]. Expressed per 10% decrease in carbohydrate as percent energy intake, the total energy expenditure effects in shorter and longer trials were −14.5 kcal/d and 50.4 kcal/d, respectively."
These effects are significant but not major. Moreover, a re-analysis by Guyenet & Hall with slightly different methods, arguably better ones, finds the effects are overestimated. By their account, low-carb diets on average only result in a 70 Calorie higher energy expenditure than high-carb diets.
The small effect size explains why most studies find find equal fat loss in high- and low-carb diets in carb-tolerant individuals.
There is no established mechanism by which low-carb diets increase energy expenditure, which is why I was very skeptical of this finding, but now that these data have been reanalyzed multiple times with consistent findings, it appears so far the effect is real. These analyses controlled for protein intake and body weight and all food was provided to the participants.
A nice little bonus for low-carb diets.»
Here is the meta-analysis he refers to:

If exercise doesn’t raise your TDEE, cut down on carbs, lol

I have actually followed this specific literature and debate from both sides closely for a couple of years and have read all the relevant papers. Even if it does make a difference, the difference is not substantial enough to practically be meaningful in my opinion.

Agreed. I don’t find this plausible - just hilarious given all the recent TDEE stuff on the forum.Originally Posted by Heisman2

you seem very, very focused about this TDEE thing....

You know what the key to understanding TDEE is?Originally Posted by EiFit91
Track calories and bodyweight.
Don't need a study for that

For sure. I don't think I've ever seen a study past a simple one that wasn't without it's flaws. People taking something simple and making it complicated and more times than not the studies were flawed anyway which always brings us back to the basics. However without these flawed studies we wouldn't have anything to argue aboutOriginally Posted by EiFit91

I would say it is definitely plausible in theory. IOriginally Posted by EiFit91
For example, if shifting from predominantly carbohydrate-based metabolism to fat-based leads to increased futile cycling of fatty acid esterification/metabolism with ketone bodies then you could have more calories burned. Similar to how the TEF can vary by macronutrient. You can theoretically come up with explanations for almost anything. 🙂
In this case some of the methodology is still questionable so it is hard to know for sure, but either way it is going to be at most a small impact.
