From solely a body composition standpoint you could and still get the results you wanted. If you happen to value your health, you do need some modicum of micronutrients which GENERALLY are found in higher quantities in whole and minimally processed foods. Also, certain people have intolerances to certain foods and can perform better with a certain food vs a substitute. More intensity in the gym is great but that's not directly related to results. So my point is it is best to vary your food sources and no source of food is bad (besides artificially hydrogenated oils) in the context of a WHOLE diet. You cannot examine a food on its own as good or bad since its the diet that makes the difference not the food. To use a popular fallacy that was used in this thread, appeal to an extreme, "eating ONLY broccoli and nothing else for your macros is just as unhealthy as eating nothing but pizza". Macros and micros are lackin in both instances. Vary your food sources and don't have a heart attack if you decide to include the fries, burger, pizza, fast food or what have you IN MODERATION IN THE CONTEXT OF YOUR WHOLE DIET!
