Adopting natural food diet as a weight trainer

Ive been into weight training now for about 7 years on and off, over that time ive tried adopted the typical bodybuilder style diet, high protein, low fat with varying carbs. This type of diet is supposed to support a lean muscular physique. Im not sure the diet did me any favours to be honest, i consumed lots of artificial vitamins, whey protein powders, skimmed milk, lean meats, egg whites etc etc ive had some terrible bouts of insomnia and bladder irritability during the night which could have something to do with the diet?Anyway i happened to stumble across nourishing traditions and after reading the first few chapters scrapped my current bodybuilder diet in favour of a more traditional one.The thing is my protein consumption has now dropped in place of more fat and im not sure whether this will support my bodybuilding goals? I want to remain lean around 10-12% bf with a good level of muscularity.Has anyone any knowledge or experience of this? high fat diets are certainly unheard of in any bodybuilding literature i've come across.Heres a typical comparison of the two diets on a day during week:Bodybuilder diet:0730 hrs - 80g Porridge oats (not pre soaked) with 300ml skimmed milk + Brown Sugar cooked in microwave. Protein shake with 30g whey protein powder with 300ml skimmed milk + cheap honey1000hrs - 500g natural low fat yoghurt with raisins and nuts and a banana1200hrs - sandwich with dry wholegrain breadcake, turkey (Real turkey) and cranberry sauce and an apple.1600hrs - four eggs lightly fried in sunflower oil with two pieces dry wholemeal toast, glass of orange juice1930hrs - chicken breast lightly fried in sunflower oil with onion and peppers, commercial spice mix e.g old el paso2200hrs - protein shake with 500ml skimmed milk, 30g whey protein and cheap honeyTraditional diet:0730hrs - 80g porridge (pre soaked overnight in 300ml raw milk), gently heated in pan until luke warm, Maple syrup or raw honey added,1 pint of raw milk to drink.1000hrs - 500g natural low fat yoghurt with raisins and nuts and a banana1200hrs - 2 tins mackeral and a banana1600hrs - four poached eggs with 2 buttered pieces of wholemeal toast1930hrs - homemade shepards pie, or homemade chicken broth with chicken breast and vegetables blended in.2200hrs - 1 pint raw milk and 1 piece raw honey and butter on toastOh and ive started supplementing with dessicated liver and fermented cod liver oil.
