My experience has been enough to make me not willing to pick up and cast any stones.

How many calories do you burn? It would take quite a bit to offset that. I can sometimes burn 2,000 on a high exercise day, but I’m also taking in 3500-4000 or more on a day like that. I would also lose weight quickly if I sustained that.
Also, it’s fair to not cast stones. I would argue that the general rules, whatever they might be, should be expected to work in most cases. If people aren’t achieving their weight goals, then they are overestimating or underestimating either caloric intake or caloric burn (or both). That’s a far more likely case than people who just have the metabolism of a hummingbird.
