To the degree the body diverts any housekeeping or thermogenic calories to exercise calories, which from basic biological adaptivity and thermogenic control must be true at some level, that math will be misleading. Not that doing x work doesn’t burn y energy, but that +x work in exercise does not burn +y energy at the end of the day. Exercise is an alternate heat source, approximately 1-to-1 with thermogenic heat (al…
>It is interesting that during periods in which I have a habit of daily low intensity exercise, I feel like I have more energy than periods I don’t do any exercise, even if my calorie intake is the same. In the same vein as much of the rest of what you're saying, the other thing that I feel like people always neglect with their "Calories in/calories out" and "Bodies can't violate thermodynamics" is that the human bod…
There have been so many of these threads where someone says "CICO!"
But, biology is complex! So, thank you for summarizing a few of the many complexities here!
