“women who are in their reproductive years need around 35 grams of good protein highquality Lucine oriented protein within 45 minutes and we see that women who are per menopausal onwards are 40 to 60 grams because we become more anabolically resistant to food and exercise as we get older”
Main Takeaways:
- Women in their reproductive years should consume about 35 grams of high-quality, leucine-rich protein within 45 minutes post-exercise.
- Perimenopausal and older women need 40 to 60 grams of protein post-exercise due to increased anabolic resistance.

“exercise causes Lucine to be taken up by muscle where it activates mtor in muscle to build and repair muscle rather than spending time in the bloodstream triggering mtor in the vascular system”
Main Takeaways:
- Exercise promotes the uptake of leucine by muscles.
- Activates mTOR in muscles which aids in muscle building and repair.
- Prevents mTOR activation in the vascular system, potentially reducing risks associated with its activation there.

“I think it's also important to understand how nutrients work right so we're going to talk a lot about amino acids and probably in particular Lucine”
Main Takeaways:
- Emphasis on understanding how nutrients, specifically amino acids, function in the body.
- Lucine is highlighted as a particularly important amino acid.
- Understanding nutrients is crucial for comprehending broader biological processes.

“Joe avick he had a paper in JBC where he looked at amino acid regulation of mtor this was this is before the lomes he was looking at the activity of using S6 kyes and he basically found a couple amino acids that mattered he found Lucine you know a very common essential Branch chain amino acid an important component of of whey protein for example that people take Arginine a very basic amino acid technically not essential lots of nitrogen in in that amino acid and those were the two big ones that he found.”
Main Takeaways:
- Joe Avick's research identified specific amino acids, Lucine and Arginine, as significant in the regulation of mTOR.
- Lucine is an essential branched-chain amino acid, commonly found in whey protein.
- Arginine, although not essential, is noted for its high nitrogen content.

“the Holy Grail was how is Lucine detected that was the thing we wanted to know literally for decades and the reason was is that there's a lot of literature in mice in humans in big animals um you know used in farms that Lucine does cool stuff like boost satiety you know feeling of of having fed boost muscle mass and eventually we found it we found the receptor for Lucine it's a protein called sestrin.”
Main Takeaways:
- Lucine has been extensively studied for its effects on satiety and muscle mass across various species.
- The receptor for Lucine, identified as sestrin, plays a crucial role in its detection and subsequent biological effects.

“the immediate idea was hey can we mimic the anabolic effects of Lucine without taking Lucine can we make something better than Lucine and and we've managed to make things slightly better but nothing dramatically better and the structure tells you why because it's it basically is made to fit Lucine and nothing else”
Main Takeaways:
- Research aims to mimic the anabolic effects of Lucine without directly consuming it.
- Attempts to improve upon Lucine have yielded only slight enhancements.
- The molecular structure of Lucine is unique, making it difficult to replicate or improve significantly.

“High quality protein has the greatest percentage of an essential amino acid called Lucine. Lucine is not made by the body, it has to be taken in from the outside.”
Main Takeaways:
- High-quality protein is rich in an essential amino acid called Lucine, which must be ingested as the body cannot synthesize it.
- Lucine is critical for muscle function and health.

“what makes insulin go up well two things refine carbohydrate and sugar those are the two things that make insulin go up in addition Branch chain amino acids make insulin go up as well Lucine isoline veine which is in cornfed beef chicken and fish processed food”
Main Takeaways:
- Refined carbohydrates and sugars are primary dietary factors that increase insulin levels.
- Branch chain amino acids also contribute to increased insulin levels.
- Awareness of these substances can help manage and potentially lower insulin levels.

“the evidence would support two to three times that amount closer to 9 n gam of Lucine per day and just to calibrate us n gram of Lucine again is essential amino acid we can only get from food per day what does that equate to in terms of the total amount of let's say egg or steak protein that one would need to eat in order to ensure that just rough roughly yes.”
Main Takeaways:
- Evidence suggests that the intake of the essential amino acid leucine should be two to three times higher than current RDA levels, around 9 grams per day.
- Leucine is crucial for muscle health and cannot be synthesized by the body; it must be obtained through diet.

“is there a place for supplementing Lucine and other Branch chain amino acids specifically you know I always assumed that supplementing with Branch chain amino acids was kind of the unique domain of people you know post exercise trying to build more muscle but as you're telling me all this it seems that adding Lucine in powder form to a meal seems like it would be great for muscle health”
Main Takeaways:
- Supplementing with Lucine and other branched-chain amino acids (BCAAs) can be beneficial for muscle health beyond just post-exercise recovery.
- Adding BCAAs to meals can help augment dietary protein intake, especially in older adults or those with lower protein consumption.
