I'm all for solid foods PWO, personally I've experimented at length with both oats and rice, and for SURE prefer rice PWO. Faster acting, still filling, less fiber and fat as well. Oats are great for low GI carbs during the day when you are cutting, but for PWO, even a half cup adds 3.5g of fat, which obviously slows absorption, and 4g of fiber, so 4 of the 27g of carbs are fiber, so you are really only getting 23 ish g of carbs from it PWO. quarter cup of rice is only about 10 more cals than a half cup of oats, and I'd rather have my cals come from carbs that are going to be immediately used rather than fat.
