Outside of the spaghetti which I assume has tomato sauce on it, I don't see any vegetables. Now granted vegetables are usually low in calories, but they are also loaded with nutrients your body needs. The walnuts are good for you but have you considered adding in some other kinds of nuts or seeds and possibly some avocado?
Are you really eating 8 peanut butter sandwiches every day? Or am I reading this wrong? And if you are you might consider other options just to keep you from getting board.
Without actually logging any of this I would tend to think that it's really high carb and possibly low fat, but maybe also low on protein, (although I'm not familiar with Cytogainer). Just exactly where are you hoping to add this weight? Because too many carbs will just add layers of fat, not muscles.
