For those that want to stick with thermodynamics, imagine an organism that stores 1% of consumed calories as fat, and uses the other 99%, and that cannot - for whichever reason - turn fat back into calories.
Completely in accordance with thermodynamics, and yet, "just eat less" doesn't work.

That organism has been outcompeted (darwinized-out) long ago by other organisms that are able to.
Being more specific, humans are not that organism.
