If you’re a vegan, you’re a strict vegetarian, and you don’t eat anything from an animal — not even eggs or dairy. If you’re a really strict vegan, you may not even eat honey or wear leather.
A vegan diet is heavy on fruits, vegetables, nuts, and grains, and since only animal products contain cholesterol, vegans are often thinner and healthier than the steak-and-potatoes crowd. On the other hand, eating out with a vegan can be problematic, since it can be difficult to find a restaurant that serves something they can eat. As you no doubt noticed, vegan is related to vegetarian and vegetable.
