What happens if a long-time vegetarian eats meat?

It can have an affect, but nothing serious, try eating small portions, adding something like yougart or fruits with a high enzyme content like papaya or mango even persimmons, I am a lacto-ovo vegetarian 90% of the time, I still eat a burger here and there, chicken once in a blue moon, fish and seafood at chinese restaurants, mainly for the protein and minerals.

But if you intersperse your diet with the occasional meat or fish meal, just be careful on the portion size and help it with a digestive helper, even papaya extract tablets juices or a great drink is a mango lassi, an Indian youart and fruit like shake serve in Indian restaurants to aid with the heat of the food, it also aids with digestion and tastes great too.

Vegetarian Eats Meat

Your body is pretty good at what it does, so it doesn't keep making things it isn't using. If you are vegetarian, your body will stop making the enzymes that digest animal protein. If you eat meat after being a vegetarian for a long time, you will probably throw up, or at least feel queasy. Your body will start making the enzymes again if you eat meat a few times.

I've been a vegetarian for 2 years and the first time I ate a meal with a lot of meat in it it made me feel sick. Sure you would digest the meat but meat takes much longer to digest then plants do.

Some people admit to not feeling well when they eat meat or other animal products after a long respite, but others feel stronger. So I would say it's to do with an individuals body rather than loosing the enzymes to break down meat.

It will take much longer to digest leaving the person bloated. This usually happens after not eating meat for a month. When I first tried to go vegetarian I went cold turkey. Then I ate a cheeseburger. I was bloated for 2 days.

the most that will happen is that you get a little bit of an upset stomach for the first 3 or 4 times you eat meat, providing that you eat one portion that is (and most eat well over a portion of meat in one go, one portion of meat is surprisingly small) if you eat to much it might make you sick, but otherwise, it will (sorry it sounds so crude) come out of the other end.

the enzyme would be reproduced by the body when it recognises it and the effects of an upset stomach will go .

It depends. I've stopped being vegetarian before and sometimes I get sick. Sometimes I don't. It depends, I think, on how long you've actually been meat-free and on what specific meat product you eat. For example, if you got fish sauce, you probably wouldn't get sick (other than from the nasty smell) because it's already fermented and taken in small amounts. If, on the other hand, you decided to eat a pound of bacon, you'd definitely get ill.

No-your body doesn't "lose" enzymes. Your small intestine and gall bladder may have a hard time dealing with that amount of fat all of sudden, so often people will feel ill at first.

I think this is propaganda intended to imply that not eating meat somehow alters your GI tract, making it weaker (by omnivores), or that our that specialized substances are required in order for the GI tract to deal with meat, showing how hard on your body it is (by vegetarians).

Our bodies were designed to deal with all types of foods-the decision to avoid killing other creatures to live is a function of the cerebrum, not the GI system : )

You may just feel ill for the first few times you have meat because your stomach won't be used to it. But you will still be able to digest it.
