Inmates that are in disciplinary hold, also called the Special Housing Unit (SHU), or the hole, or the "box" are given three square meals. In fact, they are given hefty portions to keep them calm. Food is the least of their worries while isolated there. Inmates in this situation are usually restricted from buying too many items from the commissary making it near impossible to feed themselves.
