I had a question about diets whether it is lean muscle gain or a bulk diet, I want to know how many stick to the same ones and just add/subtract the macronutrients. I just worry about that if I am constantly using the same foods my body will adjust and not get the effects I once did.

That’s one of the most unnoticed or unrealized facts about bodybuilding nutrition. Whether you are precontest, offseason, gaining and losing, whatever – the foods are the same and really the diets are the same. It’s just more or less of it. And another undeniable fact is that a diet that has worked for you before will work again.
I wouldn’t get too concerned about your body adapting to the foods. There are competitors who have been eating the same stuff for decades and still make improvements. But if you are concerned about it or just bored with what you’re eating, then you can switch back and forth from different meat and proteins sources. But of course the list of foods that work is pretty limited. Here’s a list of permissible bodybuilding foods (aka foods that promote muscle growth and fat loss):

Protein
Best sources of protein for building lean, shapely muscle while you are cutting your bodyfat percentage are: egg whites, turkey breast, chicken breast, fish, whole eggs, lean beef (90% or leaner), salmon and very lean pork. The best protein supplements are Ultimate Muscle Protein, Ultra Size, and Muscle Provider.
Mass amino acid tablets and Ultra 40 are invaluable to make sure that you utilize the protein you eat and they provide additional amino acids you need to build muscle.
Complex Carbohydrates
Best sources of complex carbohydrate for losing fat while you gain lean muscle are oatmeal, brown rice, sweet potatoes, and all black or red beans.
Low Carb Vegetables and Fruit
Low carb vegetables include salads, broccoli, cauliflower, spinach, green beans and just about any other green or yellow vegetable. Low carb fruits are blueberries, cantaloupe, grapefruit, peaches, and strawberries.
Fats
Fat is critical to your health and essential to your success as a dieter. Best sources are olive oil, coconut oil, flax oil, sunflower oil, safflower oil, canola oil, almond butter, walnuts, and avocado. We will also give you an option of using a tablespoon of heavy cream in your protein shakes and protein pudding formula - but only if using Beverly Proteins. Don't even think of adding cream if using another protein powder. You should also take an essential fatty acid supplement like Beverly’s EFA Gold or a fish oil supplement.

Thanks for the list BookerT....very helpful.

Maybe this is stupid, but would yams fall under the "sweet potatoe" category?

Thanks!
