Post Workout (PWO) Nutrition



"The idea of a PWO meal containing carbs (and protein) is to take advantage of a period of time in which the muscles are particularly insulin sensitiveve. We can fly nutrients into the muscle “under the radar” via a mechanism called “non insulin mediated glucose transport”. Amino acids are also taken in during this time and may play a synergistic role in both glycogen repletion but also decreasing inflammation that accompanies hard training. Said another way, you recover from exertion faster. 


So, what should ya eat? We actually want a starchy carb as our primary carb. Yams and sweet potatoes are great options as they are also highly nutritious. Fruit should be used sparingly in this meal if one is focused on optimized glycogen repletion as fructose refills liver glycogen first, and once liver glycogen is full we up-regulate the lipogenic activity of the liver and start down the road towards fat gain and insulin resistance.


...part of what we want with this PWO meal is the MAINTENANCE of insulin sensitivity. If we totally top off our glycogen stores PWO we impair insulin sensitivity and make it damn tough to lean out. So, one way to look at this is the a LC-PWO meal is focusing on muscular recovery and growth, while minimizing or limiting the effects of insulin or carbohydrate. This is in stark contrast with what we will see in the case of the high carb PWO meal. From my perspective this is THE PWO meal of choice from a health promotion standpoint.


For low carb meals, in this situation the PWO meal of whey protein + coconut milk is providing quickly digested protein which will reverse catabolic actions of training, with just a bit of fat to suppress the normal glucose release of a large protein meal via glucagon."
