[Star Trek] You get your own personal holodeck and go live there. All your food is holodeck food. Does it provide the nutrition you require? What happens if you eat nothing but holofood and then leave the holodeck?

For question one: We need to determine how real things are in the holodeck. I can think of sources both ways that things are completely real, and not real that real. 

For question two: Say the eating holofood is for a year. Enough time to have a significant portion of your body created from / sustained by holofood.

The Holodeck also uses replicator and transporter technology.  Some items that people interact with, that would need a high fidelity, are replicated and transported into place.  The program/computer determine this as needed. The same goes for food.  It is replicated and transported into the simulation.  The food you eat is real, as you can't eat something that is made up of holograms and forcefields.

If you eat food on the holodeck and leave, you are just fine.
