I liked it a lot, it was compulsively readable, but it made me feel like achieving long healthspan is a more monumental task than I might be able to handle, and it constantly made me reflect on my Diabetic brother's impending doom because he does nothing for his health at all.

That said, there are a lot of things I can do, mainly getting my sleep routine under control, a nightly problem, and two, adding strengh training. The book is very motivational.

I have been trying to fast every night for over a year and am rarely successful longer than a week (16:8), but when I do fast, I lose a lot of weight. I would still like to make it a rule to not eat after dinner, so switching to a 15:9 window, while being sure to get enough protein, is my new goal. He was emphatic about protein and for the first time I had a clear idea of how much I need.

I trust him as a medical expert more than someone like Mindy Pelz or Andrew Huberman, or even in some respects my own doctor. He is dominating my YouTube feed now and I prefer to listen to his podcasts instead. He reinvigorated my already strong interest in metabolic and cardiovascular health. I do not find it possible to ask my doctors for the tests he recommends; either they will not order them or I'll have to pay out of pocket. So it's best to just make some tweaks and heed the precautions and step up my exercise routine, and sleep healthfully. As I enjoyed learning anew, exercise is the panacea.

Very enjoyable read. It only took a few days.
