I dont know how many times I went forth and back trying the vegetarian diet. I even had stints with vegan and raw. In my mid 20s I became a vegetarian for about 8 years. I remember the last years I had tons of allergies, was often sick, my skin did not heal well, I was B12 deficient, I was always hungry it seemed, and got fatter by the year. Looking at some of those vegetarian websites its mostly grains, beans, breads, and pastas it seems.
It appears its even more difficult to eat balanced being a vegetarian. I wont go back to be vegetarian, since I hate beans, rice and tofu (GMO), but will tolerate lentils, mung beans, and chickpeas. Maybe once a month I can find a vegetarian recipe worth making. I think I rather juice or fast for a day then eat beans.
