Only if you eat about ten thousand of them! Yucky, yuck, yuck! I can't tell you how many people have asked me this strange question throughout my 18 years in the fitness industry. Too many to count. So! To anyone else who may be concerned about the belly bulging effects of fingernail chewing, here is my answer.

I'm not exactly sure how many calories are in each nail per se, but since they are made of keratin, a sturdy fibrous protein....it couldn't be much.They'd probably just run right through you. In fact, I think you'd have to chew through the hands and feet of everyone you know to even equal a moderately satisfying snack. Hmmmmmm. Yummy!
