What do you call a person who is supplied with regular meals and is typically a lodger?

The term used to describe a person who is supplied with regular meals and typically lives as a lodger is "boarder." A boarder usually pays a fee not only for accommodation but also for meals provided by the host, which distinguishes them from other living arrangements such as simply renting a room.

The role of a boarder involves a more integrated living situation compared to a tenant, who rents a property and may not receive meals. Unlike a roommate, who shares living space with others on equal terms, a boarder typically pays for their meals and lodging as part of a more structured arrangement. Additionally, a subscriber generally refers to someone who subscribes to a service or publication, which does not apply in the context of lodging or meals. Understanding these distinctions helps clarify why "boarder" is the most accurate term for someone in this situation.
