THE ANABOLIC WINDOW IS A MYTH: POST WORKOUT NUTRITION EXPOSED

If you’ve been around the fitness industry for even a small amount of time you’ve likely heard the echo chamber proclaiming that you have a small window of opportunity after your workout to get specific post workout nutrition into your body in order to have your muscles recover properly with nutrient timing.

This seems like a reasonable claim. However, does the research back this up? Or is it just a convenient and cleverly devised way to sell you another protein shake?

In today’s video we’re going to do a deep dive into the actual research, and I’m going to show you that – the anabolic window and this type of nutrient timing in general – is indeed a myth.

Claim – eating immediately after workout can inhibit the proper inflammation response to signal recovery pathways to begin. The increase in muscle protein synthesis and insulin sensitivity lasts far longer than the proclaimed 30-45 min window.

Definition – Also known as the metabolic window, commonly referred to as nutrient timing, is the period of time after training where insulin sensitivity and protein synthesis is increased and allows for more nutrient uptake of cells.

The Current Bro Strategy – Ingestion of quick digesting protein and carbohydrates within 30-45 minutes post workout to see benefits in body composition, performance, and recovery.

Is This Post Workout Meal Strategy Best?

https://www.ncbi.nlm.nih.gov/pubmed/9044226 (This study shows that there was no difference in glucose and insulin between groups who were fed 0-4 hours post exercise or 2-6 hours. As long as sufficient carbs are ingested there is no difference in either group during recovery period.)

https://www.ncbi.nlm.nih.gov/pubmed/2055849?dopt=Abstract (This study shows that 2 hours post exercise without caloric intake there was still significant replacement of glycogen storage.)

https://jissn.biomedcentral.com/articles/10.1186/1550-2783-10-5 ( evidence suggesting that anything within 3-6 hours of post workout activity will still allow for anabolic recovery. Also claims that most evidence to support this post-workout anabolism theory is hypothetical.)
