Eric Helms Goes in Dry on Feiggenbaum, Claims Exercise Raises TDEE

Eric was on Mike Matthews this week and he made reference to the 2021 TDEE & exercise study that Feiggenbaum has now-famously misinterpreted. He alludes to the "Hadza" study I mentioned in the old thread, where the TDEE of highly active hunter-gatherers from the tribe was found to be the same as sedentary Westerners who were matched for body size/age/sex. He compares this with similar studies done on the highly active "Quaker" farming communities, who have very high TDEE's (up to 5k+) and are very lean. Helms argues that the difference is related to the "RED-S" syndrome, wherein the amount of energy intake is insufficient to match the output in activity, so the body compensates by down-regulating hormones and slowing other bodily processes. The Hadza had no increase in TDEE despite their activity because their bodies were halting or slowing processes in order to stay alive due to their meager intake. They in essence were experiencing RED-S. Helms argues that they likely have far lower testosterone and have much smaller adult heights due to their chronic low energy availability. The Quakers, on the other hand, had very high TDEEs due to their sufficient energy intake.

This adds a whole new variable to the equation. Does exercise effect TDEE less in people who are either exceptionally lean or dieting compared to healthier people eating at maintenance? Is this yet another reason why some studies show exercise to be far better for weight maintenance than weight loss?

I think this could be a very interesting factor to consider.

This specific discussion comes around 25 minutes in, but I highly suggest anyone interested listen to the whole thing.
