There is nothing childish about cereal and toast.

He didn't say "Lucky Charms" and "toast loaded with grape jelly".

I eat a low carb meals also, and I totally get not wanting a sugar crash due to eating a carb-loaded breakfast. But sheesh "Well, you could try eating like an adult" just sounds terribly condescending to me.

Plenty of adults eat cereal and toast for breakfast and are just fine doing so.
