Mike with PricePlow back at you with a MASSIVE update!
We start things off with the latest news, since there’s some really good stuff.
Nutrition News – January 13, 2014
There’s been a bunch of things going down in the industry recently. Here’s a recap.
The “Protein Window” is Nonsense?
Alan Aragon and his team published a massive meta-analysis of over 43 studies about “Protein Timing.”
Their conclusion? It’s basically BS.
In their research, they determined that the most important thing for both strength and hypertrophy (muscle growth) is the quantity of protein. Not whether protein was used within 1 hour before workout or within 2 hours post workout.
It’s mostly all about hitting those numbers. Not necessarily all at once, but it doesn’t necessarily have to be pre/post workout either!
His findings discuss that there are two problems with most of the studies they assessed:
- The fact that many of the studies did not control the total amount of protein. Those who did not consume protein during those windows often had lower protein consumption in general. This lower amount of protein is what the analysis’ statistics show to be the real problem.
- Many studies used untrained participants. “Beginner gains” occur almost no matter when when dealing with untrained subjects, so it is important to factor that into the analysis, and also look closely at what happens in trained subjects.
Aragon and the research team then go on to postulate that the fabled “anabolic window” may actually be as long as 4-6 hours, but it is difficult to determine.
In his earlier discussion from last year, Nutrient Timing Revisited, the team also discussed some other strategies. It all boils down to a bit of common sense – it is “safe” to get protein in roughly 90 minutes before — and 90 minutes after — a 60 minute workout.
Either way, the basic statement is that you don’t need to get protein in immediately before or immediately after your workout. You just gotta hit your stinkin numbers.
It’s all very interesting.

2018 / 2022 Update: Aragon also had an article published on the matter in 2018, and in 2022, it was granted open-access so that everyone could read it!
Fat-Loss Study on EGCG + Resveratrol: Short Term Success!
A new fat-loss study has been done on EGCG, the green tea catechin, along with resveratrol. Conclusion? It works! At least in the short-term, as this was a 3-day study.
The researchers showed that when mixing EGCG (282mg/day) + Resveratrol (200mg/day), both energy expenditure and metabolic flexibility were improved compared to placebo in men and women.
However, when soy isoflavones were added in at 80mg/day, the effects were reversed in women! Metabolic flexibility was measured by the respiratory quotient after lunch or dinner meals (post-prandial).

We don’t have an EGCG category, but you can see some EGCg products in our Green Tea Extract category. We need someone to write this page now!
