I don't think so, unless you're dieting down. I can kill half a dozen at breakfast without batting an eye. I plan on pounding the hell out of them once I hit my cycle. We get them for about $.069 a dozen around here, so it's definitely cost effective.
i have been eating more than that for years,i have 10 whites just a t lunch,you are only gettin 3-3.5 grms protein in the white,at my morning break at work i eat another 10,
