Fiber takes a while to break down, specially raw, so makes you feel full. Protein can have the same effect, but it's much more calory dense so you might inadvertently be consuming more calories than you need - but if that's your goal, go for it, just pointing out that not feeling satiated does not mean you didn't eat enough for your body. Vegetables also have more micro nutrients than meats, specially raw. Legumes (bens, peas, etc) are a good compromise between vegetables and proteins too.
