eli5: How are many male prisoners very muscular whilst in prison despite prison food often being very poor and small?

Question

Doesn’t make sense to me as many prisoners have said that meals are “about as big enough for a 5-year-old” and often are lacking in healthy elements

Answer 1

Prison food is actually not that bad. Its jail food that sucks. In jail you will likely lose weight only eating meager portions of something i wouldn’t give a stray dog. In prison to keep the inmates more content to prevent further violence you get what i would call real food. Its not 5 star quality by no means, but you get actual meats and vegetables. In the jail for my county they serve green bologna. If you complain about the bologna being green their response is, and i quote “ It’s not bologna, its protein loaf.”
