I own this book and have started into it, and have followed Greger for years.
I think focus on the personal characteristics is a temptation, but listening to what is being said and the science behind it is important. Weight lifters who look way better than Greger will be dead long before him on average.
Greger is well trained, very smart, but also biased. Not everything is fixed by a whole food plant based diet (WFPBD). A whole lot of things do much better, and so long as one optimizes their Omega 3 index and B12 - it is likely the optimal diet.
I tend to go more with Simon Hill (The Proof Podcast) on the protein side of things - however, higher protein diets are associated with shorter longevity, but it is nuanced. Dr. Longo (Prolon Virtual Mimicking Diet) talks on this a fair bit.
It would seem like going beyond 1.2 g/kg/day is unlikely to add any additional muscle mass, even if working out hard, and if not working out, with strength training 0.8 g/kg/day. As folks get older, Dr. Longo argues that there is likely benefit for more than this, at least in the 1.5-1.6 g/kg/day. All of this is super easy to do on a WFPBD.
There are lots of other dietary patterns, that enter various amounts of animal products that have reasonable health profiles - it just can’t be the principal part of the diet.
Greger, much like many others in the area of nutrition who have public followings, has a bias, then fills in the data to match. I think Greger is correct, but it is a bit oversold. It can’t fix or reverse everything, but is certainly associated with better long term health outcomes. His presentations are enjoyable to watch.
I’d encourage folks to subscribe to nutritionfacts.org …
