Vegetarianer -äter oftare och mer?

Om jag inte äter kött så blir jag snabbt hungrig igen, är det så för vegetarianer?
De måste väl även äta mycket mer för att få i sig tillräckligt med proteiner?

Protein intake in vegetarian diets is only slightly lower than in meat diets and can meet daily requirements for any person, including athletes and bodybuilders.[48] Studies by Harvard University as well as other studies conducted in the United States, Great Britain, Canada, Australia, New Zealand and various European countries, have confirmed that vegetarian diets provide sufficient protein intake as long as a variety of plant sources are available and consumed.[49] Proteins are composed of amino acids, and a common concern with protein acquired from vegetable sources is an adequate intake of the "essential amino acids", which cannot be synthesised by the human body. While dairy and egg products provide complete sources for lacto-ovo vegetarians, the only vegetable sources with significant amounts of all eight types of essential amino acids are lupin, soy, hempseed, chia seed, amaranth, buckwheat, and quinoa. It is not necessary, however, to obtain protein from these sources—the essential amino acids can also be obtained by eating a variety of complementary plant sources that, in combination, provide all eight essential amino acids (e.g. brown rice and beans, or hummus and whole wheat pita, though protein combining in the same meal is not necessary). A varied intake of such sources can be adequate, a 1994 study found.[50] Some years later, it became clear that even "combining proteins" is not necessary. As reported by Dr. Weil in 2000 in his print newsletter, and as reiterated in a 2002 post on his website, and again in the 2005 update:

"You may have heard that vegetable sources of protein are 'incomplete' and become 'complete' only when correctly combined. Research has discredited that notion so you don't have to worry that you won't get enough usable protein if you don't put together some magical combination of foods at each meal"[51]
