What are you eating?
I eat one meal most days. I just eat 3 or 4 t-bone steaks (or similar). It's quite easy to wolf them down and then I'm not hungry for 20 hours.
If you don't get enough fat or eat too many carbs, you won't feel full and will end up eating too much.
It's not about eating three meals at once, it's eating until you are satiated.
It's very easy to eat this way and it ties in well with afternoon strength training.
