About the vegetarian diet
Being a vegetarian means consuming no meat, chicken or fish, or items that contain by-products of animals. It is something most people do for moral reasons rather than as a diet per se.
Not quite as extreme as becoming a vegan, vegetarians still eat dairy products and eggs and a plant-based diet with eggs, legumes and tofu as a source of protein is ideal for promoting weight loss.
If giving up meat cold turkey (ahem) is too much for you there’s always the option of becoming flexitarian – being sort of vegetarian but with some meat products allowed every now and then.
