I think they are trying to say that you can technically lose weight without changing how you eat by spending more calories. Which... is technically true. But obviously doesn't relate to the point I was making, and I feel like they're purposefully avoiding talking about the fact that the biological mechanics of how one loses weight have nothing to do with the general population's inability to lose weight with willpower alone.

They're trying to spring some sort of "gotcha" on the fact that I didn't over-explain my terminology in a throwaway example, ignoring the rest of my comment and the meaning behind it.
