Have you ever tried Veganism? I know its both a diet and philosophy, ever tried it?
No I haven't tried veganism and I don't really have any desire to do so. Have you?
I have not, although I have considered the diet before for heath reasons.  But there are a lot of distinctions between different categories of Veganism  
Can you tell me more about the different categories of Veganism and what are the health benefits?
Well if you have a well planned diet, it can reduce the risk of some types of chronic disease including heart disease
What exactly can an individual eat on a vegan diet plan? What is restricted?
Vegans refrain from eating animal products, not just meat but also eggs and dairy products.
Eggs contain a large amount of protein and nutrients and I believe they are beneficial to one's health.
They are yes, but those nutrients are not limited to just those foods.  The American Academy of Nutrition has approved the use of vegan diets in every stage, including pregnancy 
Although I can see the health benefits of such a diet, I would never be able to give up meat and dairy.
