I actually recall reading recently that that's not necessarily the case outside of extreme levels of exercise, because the body can compensate by spending fewer calories on other things - some of which it may be beneficial to put less energy into, like producing inflammation.
Just did a quick search and found this paper, which suggests an average rate of compensation of 28%, but notes that it varies significantly: https://www.sciencedirect.com/science/article/pii/S0960982221011209 https://www.sciencedirect.com/science/article/pii/S096098222...
- trnl 3y agoI believe Chris van Tulleken recently cited another paper in his book – "Ultra-Processed People": https://journals.physiology.org/doi/full/10.1152/physiol.00027.2018?rfr_dat=cr_pub++0pubmed&url_ver=Z39.88-2003&rfr_id=ori%3Arid%3Acrossref.org https://journals.physiology.org/doi/full/10.1152/physiol.000... In it Herman Pontzer investigated the daily calorie burn of different lifestyles: hunter-gatherers, farmers, and office workers. Studying the Hadza tribe in Tanzania, he discovered that their calorie expenditure was surprisingly similar to that of Americans and Europeans. Results suggest that increasing activity won't impact total energy expenditure. But without exercise, the energy spent by bodies on other things like stress, inflammation, etc.
