How do vegetarians live without meat?

Nutrition

The main nutritional content of most meats are protein, iron and fat. There are many foods that contain these things, and can easily be substituted for meat.

Protein can be found in eggs, cheese and pulses.

Iron can be found in chick peas, bran flakes, spinach and other dark green leafy veg, etc.

Fat can be found in anything greasy! Chips/fries, nuts and seeds, cooking oils, etc.

And if you're referring to the taste, vegetarians often don't like or want the meaty taste and texture. Those that do have another reason to exclude it that's important to them, sometimes moral or religious or environmental. For some it's hard to imagine, but it's the same as some people not liking toast or not wanting to drink alcohol.

A lot of people might see it as an unbalanced diet, but vegetarians are generally healthier because they're more thoughtful about what they eat. They're often no more likely to become weak or anaemic for this reason.

Vegetarians survive quite well without eating meat or dairy products.
