depends on how you do it. Your pre workout meal should always have protein. That said if the meal is also high in carbs (40+) you would want a smaller amount of fat (less than 10). If its high in fat (25+) then get a small amount of carbs (less than 30). Or do moderate carbs (20-35) and moderate fat (10-20). So if your eating a half cup of oatmeal and 2 tbsp of peanut butter your fine, but if its a whole cup of oatmeal id only do 1 tbsp of peanut butter.
For me personally I prefer an slice of whole wheat bread, apple + 7 oz of top sirlon (35 carbs, 51 protein, 13 fat), red meat seems to make a profound difference for me
