Hmm, well, creatine will help add some bulk, but you really have to make sure that you get enough water in your system if you are going to dose creatine enough to make a difference. You will also likely want to be consuming more pottassium (those bananas and potatoes), you might look at getting something called nu-salt which is pottassium chloride as a replacement for table salt.

I would caution against raw eggs as well. Besides the salmonella threat, you don't need all that cholesterol added to your system. There are good egg substitutes out there that are a lot safer pathogenically and also no fat and no cholesterol.

As far as consuming fish goes, I would caution that you be very suspicious of where the fish comes from. Unless you have a very reliable source, you face a siginificant risk of chemical contamination. Shellfish also are higher in Cholesterol. Before I eat any fish, I find out where it was caught, where it was processed, and how it will be prepared. If it is farm raised anything fish, forget it.

Also, be careful about eating chicken breasts. You would be surprised how much cholesterol there is in a chicken brest.

Man, eating has never been so scary.
