Yeah, that’s not really true, because physics. The article’s “myth busting” is overstating the evidence. Human metabolic systems do have some adaptation. It slows down a bit when we’re not eating enough to maintain status quo, and it speeds up a bit when we’re exercising more. But it doesn’t come anywhere close to compensating for all of the effort. If you read more carefully, you will find that the article is talking about compensating behaviors, in fact quite similar to what happens to me when I overeat. The other compensating behavior mentioned in the article is becoming more sedentary after exercise, this has some of the same effect as eating, however it’s far easier to accidentally over-compensate by eating than by following exercise with couch time.

I absolutely unconsciously eat more when I exercise. I know because I measured it. And once I measured it and focused on exercising while also eating a constant amount, surprise surprise, I actually lost weight. This is well known to many many people, well studied and understood, and has a metric ton of actual data to back it up. If this article is claiming to challenge that, then this article is wrong. (But IMO it’s not actually challenging known physics, it’s just written in a misleading way.)
