I have become a vegaterian for the last while now, how can I stop loosing weight?

a few have said some pretty good things, like eating starches etc. Also, your body might be detoxifying, so don't worry about it too much, but I'd like to add this.

If you drink milk, (try to find a good source of milk, preferably raw milk) it can greatly help your losing weight problem, and also that empty feeling experienced by many who are going off of meat.
When I say drink milk though, I'm talking about eating too... you can turn milk into curd and whey by bringing the milk to a boil, and then adding lemon or any acid, (citric acid, vinager).
After straining out the curd, you can press it a bit, and it is wonderful food, which you can fry, or just add to any veggie stir fry, bake with etc.
Also there's cheese, cheese will always make you feel that solid feeling, and it's packed with protein etc. (i like to use the raw milk cheeses from the healthfood stores.)

don't forget your lactic acid milk products. These are the nicest and healthiest of foods. They are full of beneficial bacteria.

One thing that is probably of paramount importance, is just the fact that you have cut something out of your diet that was a major portion. Now, you have to replace this. You must find out recipes, and or places that cook vegetarian foods. If you just stop eating meat, you will find that you may be feeling weak and skinny. But you must replace the meat with wonderful foods, of which there are almost limitless varieties!

I hope this helped you a little.
