Hey everyone I've started going primal recently and my dad as been going crazy over the fact that all I eat is meat, fat, and veggies but no potatoes, rice , bread and all that other stuff. Basically he's convinced that if I continue on this primal diet that I'll end up dying from liver failure or a heart attack.

Can anyone think of ways to convince him that I won't kick the bucket because of this diet? He's starting to get angry with me (Out of fear for my health).
