True, and our perception of calories out is equally flawed. The average healthy adult male is supposed to burn 2500 calories a day. What if you're not average?
Maybe those people who are naturally skinny are doing 2800 a day and the fat people are 2200. 300 extra a day will add up to some serious weight gain in the long term.
Not to mention, maybe 21yr old you was at 2500cal but 35yr old you is only 2300.
So many people blindly carry on as if they're either average or young, wondering why they're still gaining weight. Then they'll start saying silly things like the laws of thermodynamics don't apply to dieting...
