What is the best meat to treat when it comes to not being a vegetarian and has been vegetarian?

I would say fish or chicken because it has less fat. Also, start out will small amounts, maybe 2 ounces once a day and then after a couple of weeks, twice a day. Eventually you can try lean beef maybe once a week.

You'll need to start out slow, your stomach won't be use to digesting the proteins that come in meats. Maybe fish or chicken. You might wanna consult a doctor.

Anything that isn't highly seasoned or smoked, in small amounts. Try to get a lean cut of whatever you decide on.

might as well start killing animals now that you're taking a job killing people. Start with cheap hotdogs. The ones made from chicken beef and pork.
