I think you're making a common mistake in thinking about food, which is that protein is good and carbs are bad. This isn't at all true -- the majority of your diet should be carbs. Vegetables, for example, the core of a healthy diet, are carbs, whereas beef is very high in fat on purpose and hard to digest despite being high in protein and so is never weight-loss food. In general, nuts, beans, animal food, and seeds are examples of high protein foods, while most of the rest is carbohydrate. In both categories you'll find fats, which come in good healthy ones and other not so healthy ones. Some high fat foods, such as fatty fish, won't be a weight gainer, while some lower fat foods, such as white flour, will be because of how quickly the body converts the latter into sugar and if not burned quickly stores as fat. I'd suggest you find some books on nutrition to get a basic understanding of food categories before you make a plan of action.
are you looking to gain / lose weight / muscle?
Are you male / female and your age?
Scientists at the University of Illinois designed a weight-loss program in which one group ate the RDA for protein, while a matched group ate two times the RDA recommended amount. Both groups also exercised. The RDA group lost 12 pounds of fat in 16 weeks, while the higher-protein group lost nearly 20 pounds during the same time period. The RDA group also lost two pounds of muscle. This suggests that you need more protein during a weight-loss program, both to lose fat and to preserve your muscle.
When you eat a meal, your body breaks down carbohydrates into individual sugars and sends them into your bloodstream. It doesn’t matter if those carbs come from vegetables or breads. Your body needs energy, and this is how it’s produced. The result is an increase in your blood-sugar levels.
