The lacto-ovo-vegetarian diet is one I do not recommend. This diet includes eggs as well as dairy products. It does not include the flesh of animals, so, technically, it is a vegetarian diet.
The yolk of the egg is the single highest source of cholesterol in the average American diet, as well as a source of highly saturated fats. Eating two eggs a day can dangerously increase your serum cholesterol, among other problems. Also, it is a very concentrated food and can, as a result, be highly loaded with chemical residues, pesticides, hormones and insecticides.
