Nope, never with chicken wings and/or onion rings, although that would be a quick way to do it...I've been called a bottomless pit most of my life; I could do it with any food, really.

In general, though, I don't really find it hard to eat a lot and eat clean...in fact, it's quite easy, really. It can just get REALLY expensive REALLY quickly. Produce, meat/poultry, fish, cheese/dairy, etc....that stuff is costly. Depending on your macro ratio, though, it's not so bad if you're trying to get in more carbs. Whole grain/wheat products are more expensive than their white counterparts, typically, but are still cheap for what you get (think a bag of pasta, box of couscous, bag of oats, etc.).
