I exercise semi regularly and use a watch + phone combo to watch my health stats regardless of my physical activity, to include calories, so I feel like my experience is decent data. On a day that I don't work out, I burn about 2000 calories. On days that I work out (weekly run), I burn 2800 calories, but I am so hungry that I have to eat huge meals and I have consumed the additional 800 I burned within 12 hours. Perhaps weekly runs are sufficiently infrequent for my body to not get "used to" the run, fitting it into the 2k calorie burn, thus I go way over on those days no matter what, but my body is getting those extra calories no matter what, to make up for it due to how significantly more hungry I am after. Everyone I know who lost weight basically just starved themselves (net calorie loss).
