On July 20th, Mark Sisson will be 70.
Appears that his website, Mark's Daily Apple, has something in the works, as it should for this milestone. All the Primal Blueprint Laws were refreshed today. This page is a great start point for what a 70 year old can look like following realistic Primal guidelines.

And then read Primal Blueprint 101: https://www.marksdailyapple.com/primal-blueprint-101/

I bought his first book early in 2010, it started me down the LC/primal path. Or now you can read every article linked in the 101 guide.

In these 13 years, Paleo, "Keto", Carnivore, etc. has come and gone, but much of Mark's healthy advice still stands. Worried now about "ultra-Processed food"? I eliminated most of those because of Mark, before I found low carb.

One of the big changes, I stopped buying any "vegetable" oil, soybean anything, and any foods made with vegetable oil, grains and sugar are very limited. I have added back dairy, since I personally have no issue with it. Anyway, as I skim through Mark Sisson's advice over the years, as names for "diets" change, his basic lifestyle laws are solid.
