Now if I were to eat a meal after lifting, it would typically consist of some brown rice and ground beef or chicken, or a burrito consisting of chicken, beans, whole wheat tortilla, and cheddar cheese.

Hmmmm...should I say, it depends?
But really...lets think for a moment...
Exercise activates biochemical reactions in muscles that allow them to respond to insulin. As you might expect, you can't get those reactions going by sauntering over to the water fountain and even schmoozing with the "poon." There are designations to relieve insulin resistance explicit to all sorts of acitvity types, muscle fiber types, as well as how long you can rest in the aftermath to re-achieve these states of insulin-sensitivity and this "ain't no PWO window" I'm talking about either because I am not trying to sell you my oober-doober PWO shake.
My concern with oats as a PWO source of energy (not carbs nor protein nor fat) is that it can offer trouble in assimilation of other molecules as it is fiber. All the myths that exist on what will and won't cause the prototypical (and fictitious) insulin-spike "required" in prolific manner by sports supplement companies is a whole lot of hoo-ha and hocus pocus and has NEVER been based in science as ALL MACRONUTRIENTS raise insulin, just at different rates, but this is important as is governed more importantly by pre-workout requirements.
There is a reason I focus on fat and protein consumed 2 hours pre-workout rather than silly (and fattening) post-workout carbs (YAWN!).

Perhaps, but teh research is predominantly sponsored and unnecessary for body comp change as it is sports specificity - which aren't mutually exclusive but also aren't synonomous nor homologous terms.

I might agree with this protocol, but I do PWO shake, then wait 1 hour prior to having PWO meal myself.

more current studies have shown that elevated protein synthesis levels last much longer.....upwards of 24hrs following a physical bout.
of course if your business is selling fast digesting whey protein....it is not in your best interest to promote these types of findings.
consumming fat does not make you fat......excess calories do.
excess calories from protein, fat, or carb will all be converted and storred as fat.
in a caloric equilibrium or deficit, dietary fat will be oxidized for energy and converted to glucose to replinish glycogen stores.
being in the "post workout window" does not change these facts.
i would be interested in hearing doc's take on this subject.

We don't have enough time in a day, PLUS I am working on something that will truthfully solve this particular puzzle once and for all and it won't be supplement-based either. Again, I leave you with "soon."
Well, at least its not a qualified "it depends."
