It's called binge eating if you're gorging for the one meal and I also practice this.
Sometimes it will be 600 calories sometimes 3000. Last night was an entire corned beef and entire French bread, made a massive corned beef sub
I find it satisfying to eat all my designated calories in one shot.
It's like a little reward for making it 24 hours every day.
I am also the same sometimes I'm like 5 bites in and push the plate away.
I chug water when im hungry to fill up a bit.
