I used to be able to eat loads. I was at a debating tournament early in the year and they were making pizzas for everyone, me and my partner slyly managed to eat 2 and a half pizzas each. And at home I would have a second meal pretty much every night.
But since I've started eating a lot healthier and drastically reducing calories, if an opportunity to pig out comes around I literally can't eat that much anymore, which is a shame because I love eating!
