He described it, with the bravado that has made him famous: \u201cMy stomach is eating itself.\u201d He is 48 years old, has said he hopes to reach 160, and stated earlier this year that his goal by <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" rel=\"noopener\" data-afl-p=\"0\" href=\"https:\/\/x.com\/bryan_johnson\/status\/2001063756445733346?lang=en\">2039 is immortality<\/a>.<\/p>\n<p>As a doctor, I read the announcement from a specific vantage point. I study longevity science and work as a hospital-based physician, which means I spend part of my week working on how to give people more years and the other part at the bedside when the years run out. Johnson\u2019s diagnosis itself is manageable and well-studied. What interests me is the story Johnson told about <em>how<\/em> he got it, because the science tells a different one.<\/p>\n<p><a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" rel=\"noopener\" data-afl-p=\"0\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1590865825011594\">Autoimmune gastritis<\/a> (AIG) is a chronic, progressive disease in which the immune system attacks the stomach cells that make acid. \u201c\u2018My stomach is eating itself,\u2019 is not exactly accurate,\u201d <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" data-afl-p=\"0\" href=\"https:\/\/www.integratedgic.com\/blog\/supriya-rao\">Dr. Supriya Rao<\/a>, a board-certified gastroenterologist and assistant professor at Tufts University School of Medicine, told <i>Outside<\/i>. What actually happens is slower and more specific\u2014the immune system attacks the stomach lining, shutting down acid production and the intrinsic factor needed to absorb B12. The lining thins over time, in a process called atrophy, and can turn into intestinal-type tissue that no longer works like stomach cells.<\/p>\n<p>Johnson traces his diagnosis to childhood sugar consumption and a hard, stressful decade. But the arc runs backward. He already had autoimmune thyroid disease diagnosed at 21, a sign his immune system was primed to turn on itself, and <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" data-afl-p=\"0\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/18261502\/\">30 to 40 percent of those patients<\/a> show early immune signs of stomach involvement. The susceptibility predated the diet and the stress he blames, and the subsequent health \u201coptimization\u201d may or may not have changed the disease\u2019s trajectory. He has assembled one of the most measured, calculated body on the planet, and the diagnosis still hid from him for years, only to arrive anyway. (This high level of control extends beyond his biology, too. Employees have accused him of workplace misconduct, but the NDAs his companies require, reportedly even of romantic partners, keep those accounts private, per <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" data-afl-p=\"0\" href=\"https:\/\/www.nytimes.com\/2025\/03\/21\/technology\/bryan-johnson-blueprint-confidentiality-agreements.html?unlocked_article_code=1.v1A.ZI39.7jIoV7wmdSlw&amp;smid=url-share\"><i>The New York Times<\/i><\/a>.)<\/p>\n<p>From where I sit, the belief that we can fully control our own fate is a powerful engine that funds real research, so I am reluctant to dismiss it. But there are limits that no protocol overrides. There are things we can do at the outer margins, but none of them buy an exemption, and the elaborate pursuit of one is mostly reserved for people who can afford it. Rao put the limit plainly: strict tracking is \u201ca privilege of the wealthy,\u201d and even for those who can afford it, \u201cpaying attention to your body is more valuable than tracking any specific number.\u201d<\/p>\n<h2>You Don\u2019t Need Expensive, Extreme Measures to Live a Long, Healthy Life. Here\u2019s What I Know Works.<\/h2>\n<p>The better news is that what actually works is available to almost anyone. Those methods, though, are unglamorous, well-studied, and mostly free, which is exactly why they get drowned out by everything that isn\u2019t. But it\u2019s my job to remind the public that they <i>do <\/i>still exist and are effective. Here they are, in no particular order, because they all matter:<\/p>\n<ul>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Lift weights<\/strong>. Building and maintaining muscle protects your metabolism, your bones, your balance, and your independence in the decades when independence becomes the whole game. <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" rel=\"noopener\" data-afl-p=\"0\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12965823\/\">Two or three sessions a week<\/a> is enough.<\/li>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Do your cardio<\/strong>. Aerobic fitness tracks with living longer and better more reliably than almost anything you can buy. Most days can be easy; try something harder once or twice a week.<\/li>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Protect your sleep.<\/strong> The people with the most expensive protocols are often the ones who skip it, and it undoes more than any supplement can repair. Get seven to nine hours with consistent timing, and treat your sleep routine as non-negotiable. Fun fact: <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" data-afl-p=\"0\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/27067616\/\">sleeping too much<\/a> can be detrimental too, so try to max out at nine hours.<\/li>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Eat enough fiber<\/strong>. Fiber feeds the gut, steadies blood sugar, and <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" data-afl-p=\"0\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/38011755\/\">lowers the risk of the diseases that actually shorten lives<\/a>. Most people eat half of what they should. You don\u2019t need to start fibermaxxing (which can cause loads of gastrointestinal distress); consuming the recommended daily amount will suffice. That\u2019s 25 to 28 grams of fiber per day for women and 28 to 34 grams for men.<\/li>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Manage chronic stress.<\/strong> Not the acute stress of a hard workout, which the body handles, but the low, unbroken mental and emotional kind that sometimes never resolves. It is measurably corrosive, and the tools to manage it take less time than the stress does. You can see a therapist, journal, practice meditation, or even vent to your friends; all of these can make the hard days feel less hard.<\/li>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Tend your relationships<\/strong>. Strong relationships <a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" data-afl-p=\"0\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0277953623007761\">predict longevity<\/a> as reliably as anything on this list, and even better, they make the added years worth having. Protect the friendships and the standing plans, and treat them like the medicine they are.<\/li>\n<li style=\"font-weight:400\" aria-level=\"1\"><strong>Prioritize preventive care<\/strong>. See your doctor at regular intervals (usually yearly if you are generally healthy). Keep the appointments you make even when nothing feels wrong. Prevention beats treatment every time.<\/li>\n<\/ul>\n<p>The people I have watched leave this life with the most peace were rarely the ones who fought hardest to stay. They were the ones who cared for the body they were given, listened to it, and accepted that this was always the arrangement. The unshowy things on this list that require daily investment are the part that is genuinely ours, and they are enough to build a good life on, which was the point all along.<\/p>\n<hr\/>\n<p><em><strong data-start=\"60\" data-end=\"110\"><a rel=\"nofollow\" target=\"_blank\" class=\"article-content-link text-brand-primary underline hover:text-brand-primary\/85 break-words overflow-wrap-anywhere underline-offset-[3px]\" rel=\"noopener\" data-afl-p=\"0\" href=\"https:\/\/ingridyang.com\/\">Dr. Ingrid Yang, MD, JD, E-RYT 500, C-IAYT<\/a><\/strong>, is an internal medicine physician, longevity doctor, and bestselling author.
