As with most absolutist statements, the truth is somewhere in between--the inverse is true there as well. If you don't do anything to keep caloric expenditure constant and just restrict intake, your body will reduce expenditure to match the reduced intake.

And to the person you're replying to's point, where the walking/stairs/etc. involved in city life might serve keep that expenditure constant for someone who's otherwise sedentary, that's not the case for someone driving everywhere and topping out at 1000 steps a day.

There's a floor to how far your body can compensate for reduced intake - starvation. There's not such a simple ceiling to stop you from eating back up to what you exercise.

No, it won't. You need about 2000 kcal/d just to maintain body temperature. That's assuming a constant heat output of 100W. A bit less is surely possible, muss less isn't. Reduce food intake below that, and you will lose weight. Because physics.

Lots of people maintain or even gain weight on under 2000 kcal/day. BMR varies greatly with the size of the individual.

Research shown that those expenditure doesn't matter. Your body adjusts. Nevertheless, we should create an environment that encourages everyday physical activity.
