What are the two categories of anorexia nervosa?

We have two categories of anorexia nervosa, we have anorexia nervosa restrictive type and anorexia nervosa binge purge type. Now the primary component you want to remember is that both of them, by the definition of anorexia nervosa, there's the drive for thinness. So for one person, what they do, the restricting type is they primarily restrict on what they eat so they don't engage in any kind of purgative behaviors such as throwing up or excessive exercise or laxatives or anything like that. And then the binge purge type, they have the drive for thinness, which is what defines it as anorexia nervosa, however within that what they do is they do extreme exercise or they may throw up or they may do laxatives or other kinds of things like that.
