Gee, a WHOLE egg and some tuna?
You He-man, you.
You eat like a third grade girl. That is likely why you are still so freaking hungry all night long.
Eat like a man looking to build some muscle mass and I doubt you would experience the same.
If you are dieting, by guess is you are a newb...or else you wouldn't be eating so little unless you just hated having muscles on you.
