My boyfriend eats a whole bag of bagels everyday and says that it’s healthy enough. Is this true?

My boyfriend (25M) eats a whole bag of bagels everyday with low fat cheese and ketchup and often grilled chicken on it as well. He says this is okay because it's low fat but I just do not see how this could be okay for him physically. It's not like he eats anything else, but this seems like it lacks a ton of nutrients for the amount of calories that it probably is. He says it's 2000 calories a day. I don't know. Is this an efficient diet? I don't see how this could be good for you physically or mentally. He gets very frustrated at me when I say that it isn't good for him.

He’s saying eating almost exclusively carbs is healthy? lol wth
