How Not to Age — Presentation

In this lecture (recorded live), Dr. Greger offers a sneak peek into his latest book, How Not to Age.

Inspired by the dietary and lifestyle patterns of centenarians and residents of “blue zone” regions where people live the longest, Dr. Greger presents simple, accessible, and evidence-based methods to preserve the body functions that keep you feeling youthful, both physically and mentally.

I’m thrilled to release this presentation based on How Not to Age, my new book coming out in December after three long years in the making. If you haven’t seen it yet, check out the book trailer: .

Preorders are available now.

If you plan to buy How Not to Age, please consider preordering. All preorders count towards first week sales, which factor into The New York Times Best Sellers list calculations. So, the more preorders How Not to Age receives, the more likely it will make the list, which could help expose millions to the message of healthy eating. In fact, the book lands on December 5–perfect timing for holiday gifts for everyone in your life you want to live long healthy lives. So, consider getting some of your holiday shopping done early by preordering a whole stack! 

As always, all proceeds I receive from all of my books are donated to charity.

    😂dr gregor looks 23.

  • ccamire says:

    We are still waiting for your blood results and bio age calculation so we can value the book on aging, otherwise this a total joke. Be transparent like most people are talking about longevity. It will be interesting if can mention any RCT. I am sure all the studies will be about epidemiology studies which have no statistically significant results and low grade quality. We want hard data that plant based are worth taking a look.

    • MD says:

      His own health has nothing to do with the science he is reviewing. Not sure what these results would tell about the validity of the literature review he is publishing. This perception of what a credible scientist should be is not only dangerous, but completely unscientific.

    • Rodica Baciu says:

      I can’t remember a single study that looked at only one person to draw conclusions about longevity/ anything really.

      But you go ahead.

    • Bill says:

      I can’t remember seeing the evidence confirming that “Bio age calculations” were accurate, or just side-show trickery.

    • ccamire says:

      @MD would you go see a doctor who weighs 400 lbs about diabetes and how to reverse metabolic disorders?

    • ccamire says:

      Most people who have replied so far dont seem to be reading a lot about longevity, but rather feels the need to hear from the preacher himself. No wonder we have a problem with cults such as Mormons and scientology.
