I find that runners can pretty eat whatever they want and still stya pretty thin. But it is important that everyone (including runners) make 40-55% of their diet carbohydrates, 30% fats and about 20% protein. Of course, limit your intake of trans fats, saturated fats and highly processed foods and eat as much as you can of fresh fruits and vegetables.

The majority of runners in a race will not vomit after they run. However, if you eat/drink dairy products or foods that upset your stomach before a race and/or run very, very hard, there is a chance that it will happen to you. I think it happens to all runners at least a few times in their running careers.
That depends on how flat your stomach already is. If it is really flabby its going to take a lot more than a week to get a really flat stomach. If your tummy is already reasonably flat, then it might be possible to get it flat in a week. However, you are going to have to be doing a lot of working out.
Stomach in the body is a good example. Also recycling plats, garbage cans are examples
