Peter Singer the "father of the animal rights movement" and really interesting philosopher, is I think a vegan but he argues for a disclosure number on eggs and chicken saying how many chickens there were per acre, because he argues that IF the chickens lived a happy life and were killed without distress, it's ethical to eat them, and at some really low density the evidence shows they are happy.
He also makes a claim that there are circumstances where it's ethical to eat meat like if the airplane serves you the wrong meal and if you reject it they will throw it away, because the animal is already dead and your decision doesn't incentivize more death, and demanding a new meal wastes food.
So, that's what living true values sounds like to me. Not picking a rule and sticking by it, but taking each decision and weighing it against your values.
