The author's thesis, backed by a mountain of data, is that the only safe level of animal based food is zero. No milk or cheese either. Moderation simply doesn't work when it comes to eating meat. That's the data talking, not me, according to this expert. I haven't seen any data that contradicts that notion. Provide a link if you have.
As a practical matter, it would be impossible to ban meat from the diets of average Americans. But when you are talking about insurance of any sort, whether it is health or auto or hurricane, we accept the principle that risk factors can be considered in pricing. So all we need to do is charge meat eaters four times as much as vegetarians for health insurance. Over time it will create more vegetarians, for economic reasons alone, and healthcare costs will plummet.
You might say it is unfair for the insurance company to charge a higher premium for earthquake insurance to people who actually live on a fault line. But I say that's just good business.
Insurance companies shouldn't charge more to people who have preexisting or genetic problems of course, as these are things which can't be controlled. But people can certainly control their diets if they want to save money. As it stands now, vegetarians are subsidizing your cheeseburgers by paying more for health insurance than they should. (Insert counterpoint involving the non-existence of free will here.)
I want to stress that I'm not the sort of vegetarian who cares if you live or die, so long as you're enjoying yourself along the way. You can eat rusty tin cans and medical needles for all I care, so long as I don't have to subsidize it.
