Is this suppose to be in my Minecraft hamachi server?

I have a minecraft hamachi server, i'm the only person that played on there before and i noticed that my player never gets hungry/never has to eat. Is this suppose to be like this? I'm on survival mode, not creative. I'm on peaceful if this helps. I have been playing on this server for a few days now, i would think that my player would have to eat eventually. Is there something that i have to enable in start.command or something? If so, please do tell. Thank you.

Added (1). sorry not start.command i meant in server.properties.

You are on peaceful mode, peaceful mode make this happen.
