I've been a vegetarian for a year now and I love it!
Why go vegetarian? Well first of all it saves animals lives, and a lot of meat farms treat the animals badly. It's also really healthy, as long as you eat good foods like vegetables and fruits.
How to become one:
onsider your reasons for becoming vegetarian. These might include moral or ethical reasons regarding the treatment of animals on factory farms and in slaughter houses, equal food distribution, religious reasons, health reasons, environmental reasons, or a combination of any of these.
Get some vegetarian cookbooks and find some vegetarian recipes that interest you. Vegetarian dining is a great way to try tons of new foods that you may even like better than meat! There are many cookbooks, cooking shows, recipe websites, and fantastic vegetarian restaurants. You can have a great time trying so many new meals!
Take a look around supermarkets, food stores and health food shops and see the variety of vegetarian food that is available. Be open to trying and researching new fruits and veggies such as starfruit, pomegranate, grapefruit and others. Also, look in your grain isle for new grains like orzo, Joaquin, couscous, barley, alfalfa and others. They are all delicious! You'll also find that most supermarkets carry interesting foe meat foods, like veggie dogs, veggie burgers, vegan foe chicken, and veggie rib-lets!
Eat vegetarian as much as possible without giving up meat entirely. Learn to enjoy vegetarian food before you quit meat cold turkey (no pun intended).
Research your nutritional needs. Vegetarian eating is healthier than meat eating(it decreases your risk of cancer, heart disease, diabetes, stroke, and obesity), but it's still always good to make sure you're as healthy as possible. Read up on vegetarian nutrition and vegetarian eating in general. There is plenty of information on the internet and in books. Make sure that with your new diet, you're still getting enough vitamin B12, calcium, protein (most vegetarians get enough protein without giving it much thought), vitamins and minerals. It's a good idea to take vitamins and calcium tablets if you don't already.
ell parents or a significant other about your choice. Make sure you have some solid research to back you up, so that people can understand how your choice to go vegetarian will improve your health, help fit with your moral or religious views about the importance of kindness to animals, etc. When informing your family of your choice, stay calm and polite, even if they find it difficult to accept.
Start to eliminate the types of meat gradually, having "one last meal" with the relevant ingredient and resolving not to eat it again.Chicken and fish first (since these are the smallest animals, so cutting them out of your diet allows you to quickly save a large number of lives).
Pork, such as bacon and ham, after a week.
Red meat, such as beef after another week.
Shell-fish, such as crab and salmon, after another two weeks.
Make sure you eat enough food. There is protein in almost all kinds of food, so you can rest assured that you'll almost definitely get enough protein, as long as you eat 1200 calories or more a day. Still, especially if you are trying to gain weight it is important to eat a wide variety of legumes, nuts, and seeds into your diet to make sure you get enough calories and healthy fats.
Get a good variety of fresh fruit and vegetables to ensure that you keep high levels of B vitamins, iron and vitamin C.
Eat healthily. As with any change in what you eat, be careful to keep all of your food groups in balance. These are carbohydrates/grains, fats, protein, veggies, fruits and fiber
Find good meat substitutes. Some taste quite realistic, and can help when you're new to vegetarian eating and have meat cravings. Others tend to be less realistic, and are simply an interesting new food to try.
If you find yourself eating meat at times or "cheating", you can always start by just being vegetarian 6 days a week, or whatever number works for you.
