There are lacto-ovo-vegetarians which consume dairy products (the "lacto" part of that title) and eggs (the "ovo" part of that title), but they do not consume any meat, poultry, or fish.
Then there are vegans which consume no animal products whatsoever.
Of course, you can also have a ovo-vegetarian which excludes meat, poultry, fish, and diary but does eat eggs. Or lacto-vegetarian which consumes dairy products but no meat, poultry, fish, or eggs.
After doing a quick search on [url="http://www.google.com"]www.google.com[/url] I found a couple of definitions that I wasn't aware of. There is the pesco-vegetarian that eats dairy, eggs, and fish, but no other animal foods and the semi-vegetarian that mostly follows a vegetarian diet but eats meat, poultry and fish occasionally. I'm not sure either of these cases really meet the definition of vegetarian since they involve some form of meat in the diet, but what do I know. I thought I understand the definition of "is" at one time, but that has changed also.
If you are following one of these types of diet in an attempt to lose weight you will likely still have to limit your intake of sugars and starches as well if you want to be successful. Excess sugar and starch gets converted to fat and stored rather easily. Too much fruit can also hinder weight loss. If you feed your body all of the glucose (created from sugars and other carbohydrates) that it needs for energy, then it never has any need to go to its fat stores for energy.
