My brother has, for years, told me that I "eat like a lizard" because I go for so long (in his eyes) without eating every day. I never eat breakfast and I almost always have one "large" meal and one "small" meal a day, though whether the large meal is lunch or dinner depends on my plans for the day.

I don't think I ate like that when I was a kid, but I started doing it in college I think, and over time I just no longer felt hungry in the mornings; I almost never feel hungry now until at least noon or 1 o'clock in the afternoon. And on the rare occasions where I do eat a normal breakfast it kind of screws with my stomach to where I almost feel ill, overstuffed way too early in the day.

For reference, my brother is pretty healthy and at a healthy weight like I am, he just eats tiny amounts consistently throughout the day. I eat like a lizard, he eats like a chicken, haha.
