Hi Jack, thank you for your valuable feedback and for sharing your experience. Nice to meet you. I am sorry to hear about your heart disease diagnosis. I hope you are recovering well.

I agree with your comments about protein. It is only an indicative point highlighting the importance of personalized protein intake as needs vary. You are right about older people might need more protein to activate mTOR and prevent sarcopenia.

We need 9 essential amino acids for synthesis as the body cannot create them. They are leucine, lysine, methionine, phenylalanine, threonine, tryptophan, histidine, isoleucine, and valine. Branch chain amino acids like leucine make the biggest impact on mTOR activation.

This subject is close to my heart as I lost precious muscle in my younger years, making me miserable. After focusing on adequate amounts of bioavailable proteins, I gained excellent body composure in my older years, as confirmed by DEXA scans.

You inspired me to convert my research manuscript on this topic to a published book.
