In this personal monologue, Nick Norwitz recounts his upbringing in a family of elite physicians, his own academic achievements (valedictorian at Dartmouth, PhD at Oxford, MD at Harvard), and the severe ulcerative colitis that plagued him throughout his training. Conventional medicine failed to bring remission, leading him to a desperate, fringe experiment: a strict ketogenic diet, which put his disease into lasting remission. The experience revealed to him a disconnect between evidence‑based medicine and what actually works for patients, prompting him to leave the traditional medical career path. He now runs an online community focused on metabolic health, encouraging curiosity‑driven self‑experimentation, empowerment, and hope. He frames his story as a cautionary tale about the limits of standard care and a call to broaden the conversation around patient‑led discovery.
Chapters
I was this close to becoming a doctor. In fact, I did my MD and my PhD. And then I ditched it. It was a decision I made that my friends and family just couldn't understand. After watching me study hard and devote my life to becoming a practicing doctor, to them it looked like I just threw it all away. To become what? An internet influencer? Now, if this story were that simple, I would be ashamed. And I certainly wouldn't be making this video. But instead, I'm choosing to share my story with you and be vulnerable in ways that I haven't really been vulnerable with you before. I'm even going to tell you things that I haven't told my own family. And if you're wondering why I'm doing this now, it's because all Our community is growing so fast that there are now millions of you who know me, but don't really know me. Like, you know my internet avatar and that I like to nerd out about metabolic health with you, but not who I am and my why. And because I hope what we're building is a true long-lasting community, I think you deserve to know a little bit more about me on a deeper level. So it would make the most sense to back up and describe the world I come from. My dad. My dad is a doctor. In fact, he's an MD, PhD, MBA Rhodes Scholar. My mom. Also a doctor. An MD, PhD Marshall Scholar. In fact, this is me at her medical school graduation. My brother and sister are both doctors, or doctors-to-be. Their girlfriend and boyfriend are also doctors. My incredible girlfriend is a surgeon, He went to Harvard undergrad at 16, then to Harvard Medical School, and is now at a top-ranked surgical program in the country. So literally, in my immediate social circle and family, we're batting 8 for 8 doctors. And that, that was the world I was born into, the world I grew up in, and have lived in for most of my life. And as a result, my life was very much directed toward that goal. And I did well along that path. I studied hard, I was valedictorian at Dartmouth, I got a full ride for my PhD at Oxford, and then I completed my MD at Harvard Medical School. And at that point, that is the point at which it's all supposed to pay off. At that point, you're supposed to choose to become a practicing doctor, treat patients, write prescriptions, don the white coat, run a lab and get Proper grants. But I didn't. So it's like I sprinted every step of a marathon and then stopped right before the finish line. And honestly, the hardest part for me was not abandoning a goal I once thought I had, but explaining it to those who I loved. Because I don't believe I'm a self-made person. I did work hard, but it's the support I received from my friends and family and loved ones that made my successes even possible. So abandoning that path, the path they'd supported me on my whole life, felt like I was failing them. But, in the end, I didn't even apply to a medical residency. Which is a taboo thing to do, let me be clear. In a medical family like mine, it's like working all month and then throwing away your paycheck. Into the trash. It makes no sense. But it did to me. And here's my why. Because while I was studying to become a doctor, I was also living a double life as a patient. My life was literally split between time in the lab and in school and in a hospital bed, even in intensive care and palliative care. There were days when literally getting out of bed to go to the bathroom cost me more effort and was more painful than running marathons used to be for me. And when I got sick, I should describe what it was. It was inflammatory bowel disease, and I went downhill fast. It nearly took everything from me. And to describe it a bit— sorry if this is TMI— what I was going through, well, violent, uncontrollable, bloody diarrhea at least 12 times per day. In fact, you know that valedictory speech clip you saw from earlier, my college graduation? The only way I was able to give that speech was by fasting for 2 days to make sure I wouldn't have an episode on stage. In fact, you can even see in the video, my face is a little bit puffy from the corticosteroids I was taking for my ulcerative colitis flare. And the physical pain was the least of it. I lost my athleticism because I couldn't nourish myself. I lost my social life, and romance was off the table because saying, hey, I gotta go shit blood, kind of kills the mood, if I'm being honest. So that's where I was at 22, as I was finishing college and starting my PhD, then ready to go to med school. And to add irony, I had access to all the resources in the world, the resources that I thought should heal me but couldn't. Conventional medicine just didn't have a cure for me, didn't have a resolution. No matter how hard I or my parents or doctors tried to get me the best help, nothing worked, nothing stuck. So I did what any reasonable, desperate person would do. I tried things that were a little bit fringe, honestly. Not because I expected them to work, but because I really had no other options— other than, I guess, death— and I was considering that. I don't know what would have happened to me if something didn't work. At minimum, I would have lost my colon, but for whatever reason, if that didn't work, I was at a place where, although I never acted upon it, suicide seemed like an okay escape. And I don't say that to be overly dramatic or somber. It was actually just logic in my hyperlogical brain, because if the multiple choice test included continuing living like that or death, death felt preferable. But there was a third option: to try something that was outside the mainstream. And to my surprise, that something eventually worked. For me, it was a ketogenic diet. When I cut out all carbs and ate lots of fat, my disease went into remission and stayed there. And it has stayed there. And you might think that made me an evangelical for low-carb ketogenic diets. It absolutely did not. And to this day, I have nothing against a sweet potato, and if I could eat a slice of normal pecan pie on Thanksgiving, believe me, I would. But while my lifestyle gave me a new lease on life, what it did do is it forced me to confront an uncomfortable truth. I grew up in a world where evidence-based medicine was the law, was pride, was the thing you do, where hard data ruled, And anything fringe was looked down upon, and yet I was living a life that was afforded to me by an intervention for which there was no randomized controlled trial— not for inflammatory bowel disease— no evidence strong enough to make what saved my life standard of care, and yet it did save me. So what did I do then? I went looking around, and I found the most remarkable thing about my story was that it was not at all Unique. I found stories of people struggling with chronic diseases, obesity, diabetes, autoimmune and inflammatory conditions like lupus and rheumatoid arthritis, mental health conditions like depression, anxiety, and eating disorders, neurological conditions like epilepsy and unexplained cognitive decline. And all these suffering patients, in some way, shape, or form, abandoned convention to try something fringe, not because they knew it would work, but because they had tried everything their doctors had prescribed them with no success. So in desperation, they'd reach for something else like I did, and when that worked, they're left asking why they didn't hear about it beforehand. And that tension, that gap between what is effective and what is evidence-based, that was the seed of the decision I eventually made to step off the conventional path and be here with you now. Because what I found is the strongest tool in medicine is not a pill or a poke, It is curiosity. The curiosity and the open mind to start exploring your own biology, treating your body as a lab, and trying something with a hypothesis about whether it will work for you, and then trying again. And it is through this approach that I've seen countless people heal even from conditions that we think of as incurable and irreversible. So what I found living the life of a scientist, doctor-in-training, patient, And a young person growing up in the era of the internet all at once, is that the most powerful thing I can give people is empowerment through information. Not a script or a surgery, even though those can be important at times, but to show up with you with my background and say, let's get excited about biology and see how your body works. I'll teach you what I can from the latest science, but at the end of the day, what I want for you Is what I was so lucky to hold on to when I was in my darkest moments. Hope. Hope and curiosity. Hope that something will work even if it's not evidence-based yet, and curiosity as fuel to keep trying until something does work. But to be clear, my recovery story was only the beginning of my journey, my first big experiment. And ever since then, I've been living a life where I realize that taking care of my health is not a chore. It's an absolute privilege. It's fun. I get to be a scientist experimenting on my body every day, finding out what works for me and then what works better. And the best part is I get to share that with you because nothing brings me more joy sincerely than seeing that hope and curiosity reflected back at me. It's validating and more ways than you can imagine. I see it either in person or even just through comments when you find something that works for you and share it with me, when you get excited about the science with me, when you stay curious. So in the end, I am really truly grateful. I am grateful for the leap I made in my career. I am grateful for what we're building here together. And I'm even grateful for the disease that almost took my life, because if I didn't go through that, I wouldn't have this, and I wouldn't have you. Thank you.
