Are Nuts a no no?

I just tried them for the first time today post op. Had a 1 oz serving for lunch and adjusted the rest of my planned meals for today accordingly so that my calories are still reasonable. I was concerned I'd still be hungry and holy crap I'm still way full a few hours later. Not planning to eat them all the time but I've been looking for something portable I can eat and this is the first thing I've found that doesn't need refrigerated so I'm happy about that!
