I would hesitate to call anyone's choice of eating style stupid. It is simply a matter of preference. Not all diets are about fat or weight loss. The benefits of cooking food are apparent, but so are the benefits of not cooking food. I'm sure that somewhere along the line you have heard that overcooking vegetables is the best way to boil out all the nutrients, yes? This just takes the entire menu one step further. While the diet may be limiting, it's certainly not harmful in any way. In fact, the benefits far outweigh the fact that the menu can seem so restrictive. An imaginative person with just a tiny bit of skill can do quite well eating only raw foods. It's always disturbing to hear remarks that denegrate another person's choices.
