Is food the most inconvenient thing after starting orthodontic treatment?

I'm looking up various things while considering orthodontic treatment.
I was drawn to the comments saying that eating was actually more inconvenient than the surgery or pain.

I usually tend to like chewy foods or things that need chewing, like nuts.
I wonder if I'll have to change my eating habits quite a bit if I get braces.

Some people say that it gets better once you get used to it at first.
I heard some people said it was a hassle to be careful about food until the very end.

For those of you who have actually had braces, what food was the hardest to eat?
