i agree with the supports here, as what
Malice_Kaiser said,
don't let anyone tell you becoming a vegetarian is an unhealthy descision.
many meat lovers always get the wrong impression of vegetarians.
MANY vegetarians and vegans have heard this statement
OVER AND OVER; "if you don't eat meat(etc), where do you get your protein?", "you know you're not getting enough protein!" or from others who tried it, "i felt weak" "got sick" "felt more tired"
first off, you don't need so much protein intake(all depends on your weight, research "calculating protein requirements") , in my opinion, meat isn't a great source of protein.
secondly, you can get your protein in these form, which is a great source!
-tofu
-nuts/seeds
-grains/whole grains
-beans
-vegetables(yes, there's protein in some vegetables)
-fruits
-tempeh
-soy products
-meat analogue/meat substitute/mock meat/fake meat/etc
people who felt weak trying a vegetarian lifestyle may be because you weren't eating healthy and getting enough nutritions. please do ton of research before starting anything!
to avoid living an unhealthy vegetarian lifestyle, be sure to consume a variety of whole foods, such as what i listed above.
vegetarian starters do have a tough time at first, but i assure you that you'll adapt to it soon! it didn't take me that long at all, you just need to know what to eat and how much. and even though you don't eat vegetables, you'll learn to love them soon! just go slowly. if you have the willpower, i'm sure you'll be fine! honestly, becoming a vegetarian isn't that hard. my friends who were meat lovers stopped eating meat slowly because of the foods i make. XD they started not liking meat and just simply became vegetarian without knowing it.
as for your parents, tell them you're serious about this, and that you've done research on how to get all the nutritions you need.
good luck!
