How vegetarian do you want to go? You would need some kind of replacement protein that you normally find in meat. Would you eat fish, or eggs? How about beans, legumes and lentils? I think soy has a lot of protein in it. I am not a big vegetarian, but I think those are a few options. Sorry I am not much help.

I take a daily vitamin that contains all the essentials, especially iron. i have had low iron since before i was a vegetatrian so now i have to watch that evenmore closely.

what type were you trying to become? I am a lacto-ovo vegetarian, so i still eat dairy and eggs, which i think helps me get more nutrients

Nuts, nuts, nuts. They are high in protein, zero hormones and cholesterol, and they will help keep your weight up. What type of athlete are you - strength or endurance?

Thanks everyone!

I'm probably going to become a semi vegetarian, just because I don't think its realistic for me to completely give up meat and I'd like to pick something I could actually stick to right now. I'm just going to ease my way into this.

I'm a swimmer, but training involves stregnth and endurance.

Just curious, how many meals a day does a healthy vegetarian eat? How big are the meals? How often do you snack? Is someone by chance comfortable explaining what they eat during a typical day?

Why do you want to give up meat? If you should, you will need to take a B-12 vitamin so that your B-12 will maintain at a healthy level. I would not think that giving up meat would keep weight off. There are a lot of carbs in pasta, some vegetables and fruits.

I have a hard time keeping weight on, so the fact that I'm not giving up large amounts of carbs doesn't really bother me. I've also noticed a common addition to fruits and veggies is daily vitamins, and you really don't need that much B12 anyways.

As far as I know, people become vegetarian for all around better health (like less risk for heart disease). For many, losing weight when giving up meat is just a pleasant byproduct of becoming healthy all around.

The only reason I was asking is because I started having less energy and just not feeling well, and my blood work came back B12 deficient. The doctor asked me if I was a vegetarian, and I told her no. She told me I needed to take a sublingual B12 each day and that I should be feeling better and have more energy. Yes, red meat is not exactly heart healthy. I take fish oil supplements as well which is good for your heart healthwise. Bread is what I always have to cut back on if I want to lose weight. Good luck with the diet.

Eating fish is not vegetarian. It drives me crazy when people suggest fish.
Anyways nuts!! I went nut crazy when i gave up flesh and gained about 5 pounds. My fav treat is cashew hummus! You will find you will become more creative with food, cooking has become a more enjoyable expirence for me.

Your correct becoming deficient in Vit b 12 is very rare. Your body can hold onto it for up to three years! Be more concerned with getting your iron.
