I was trying to put together a menu for myself to eat and I dont think the book touched on the importance of eating veggies and if it did I missed it

Is it important for me to eat veggies and to keep my carbs closer to 20 or can I skimp on eating all those carbs and just taking vitamins and some kind of fiber supplement? (I'm not much of a veggies guy)


I saw that some of you take a fiber supp and the name of it escapes me but I can do a search on it. But, how many of you take vitamins and what kind? Would a multi-vitamin just be fine or should I take specific vitamins?

Thanks
