well I'm not at all ashamed to say, though I hope I don't catch alot of flack, I'm a vegan so I don't get any casein or whey protein. Lots of soy from milk powder and fake meats, different beans nuts, grains and seeds etc. I stay away from tofu products for the most part though because I don't want those phytoestrogens or whatever else is present and potentially bad from straight tofu products.
But anyway I weigh 195 lbs (was 160 less than 6 months ago) with 11% body fat and I have been bulking up pretty well and seeing good strength gains with 150 -200 grams of protein and 2500 + calories per day. And basically what you're saying is that I should keep up or maybe even add some protein, but cut back on the carbs and fats a bit to maintain???
