Dr Romain Cadario, Assistant Professor at RSM, led the study about why humans eat the exact same breakfast every day. Researchers say we stick to breakfast routines because it has a ‘utilitarian goal’. The way we approach our other daily meals isn’t the same. Lunch and dinner have ‘hedonic’ goals, which means people look for pleasure, so most of us wouldn’t be content with eating the same thing for lunch or dinner every day.
