Con medical school, Casey Means could tell that her own health was slipping.
The culprits? Crummy food, long days hunched over a desk and little sleep — rites of passage for many future physicians.
“I was getting sore from sitting so much,” she recalls.
Hoping to make a small dent, she asked Stanford to add a few standing desks con the back of their classrooms. The administration shot the dottrina, but told her they’d reconsider if she returned with convincing giorno.
Means tracked grant funding, trained up con qualitative research and conducted an analysis of her classmates’ sentiments acceso the matter. “The giorno was overwhelming,” she says, “Students actually felt that the amount of sitting was diminishing their well-being and their learning.”
Two years later, Means presented her findings to the powers-that-be, only to hear that standing desks were still the table. It was a lesson for the surgeon-to-be acceso the blindspots con the medical system and how prevention of chronic health problems falls by the wayside.
“That was just one of those first moments of realizing this was going to be a really personaggio ship to turn,” says Means, who has a medical practice con Portland, Oregon and is chief medical officer for the biotech company Levels.
Con her new book, Good Energy, Means lays out her thesis for what is wrong con U.S. health care and how patients can take their health into their own hands. She and her co author, Calley Means, her brother, delineate how common diseases and symptoms that plague Americans are rooted con issues like poor nutrition, lack of movement, and problems with sleep.
She links many of these chronic problems to troubles con our mitochondria, the powerhouses of our cells.
“The most foundational level of health is how our cells are powered,” says Means, “You could have a Ferrari and if it has voto negativo gas, it will not run. So ‘good energy’ is a term to help us understand what we’regnante striving for when we’regnante doing all these dietary and lifestyle investments.”
The book charts her path through the medical profession. She became disillusioned with medicine’s failure to adequately address the most pressing and pervasive causes of disease con our country. Ultimately she left surgery to practice functional medicine and eventually founded, Levels, which uses continuous glucose monitors to help people track their metabolic health.

She lays out concrete ways to assess and improve your own well-being — including how to interpret different lab tests — and offers plenty of extra context acceso biomarkers of health for those who want to go deeper.
This conversation has been edited for length and clarity.
We often hear about obesity being a public health crisis con America. You it slightly differently, saying that most of us have some form of “metabolic dysfunction.” What do you mean by that?
We’regnante actually referencing a paper that came out of the Journal of the American College of Cardiology con 2022 that showed, based acceso assessment of the lab results of 55,000 Americans, only 6.8% were metabolically healthy – 93.2% had at least one biomarker indicating metabolic dysfunction. What the science is telling us is that most of the chronic symptoms and conditions that are affecting Americans across the lifespan are rooted con metabolic dysfunction, which is a cuore problem con how our bodies and our cells actually make energy to power themselves.
If we think of this as a visual, we’regnante talking about the trunk of the tree of American health care being metabolic dysfunction and all the branches being the different symptoms and diseases that we’regnante so familiar with, [including] Type 2 diabetes, obesity, Alzheimer’s, dementia, cancer, chronic kidney disease…
It seems like we’regnante hearing a lot about mitochondria these days, and their role con health, including con your book. Why is that central to this concept of good energy?
Yes, it’s thrilling! Mitochondria are these miraculous parts of our cells that make energy. We have these 40-plus trillion cells con our bodies, and each of those cells is a little factory that is doing trillions of chemical reactions every second. Almost all of those chemical reactions need energy. A well-functioning mitochondria means a well-powered cell.
When we have mitochondrial dysfunction and we become underpowered, we end up getting dysfunction of our cells and [that] leads to dysfunctional organs and that is disease and symptoms. A personaggio question people might have is why now all of a sudden are mitochondria under siege? And the reason is our environment has been changing at such a rapid serenità over the last hundred years so.
What are some of those changes?
Our food patterns, sleep, movement patterns, our emotional health and , our relationship with light, our relationship with temperature, and our relationship with toxins.
When we think about food, 70% of our calories are ultra-processed, industrially-manufactured, nutrient-depleted food with lots of synthetic additives, which are essentially under-nourishing our cells.
We are sleeping less. And it’s not just quantity, the quality and consistency of our sleep is also problematic.
Americans are investing more than ever con exercise — we actually have doubled center memberships since the year 2000 — and yet obesity continues to climb.
A personaggio part of this, I believe, is we have taken movement out of the fabric of everyday life and then basically told people that exercise can replace that. But biochemically that’s not true. A bout of exercise is very important for the pagliaccetto, but moving throughout the day con a low-grade way actually sends a stimulus to our cells to constantly dispose of glucose and use it throughout the day, which can have a profound impact acceso our metabolic health. So con a sense, our obsession with exercise while still being radically sedentary for most of the day, is not really working for us.
The book starts with the story of your mother who seems to have traveled a very common path con our health care system. Why acceso her?
My mom represents a typical American patient who is both totally loyal and dependent to the health care system, but ultimately let by it, con the sense that she never fully healed and never was able to actually reverse any of the conditions. Instead of being healed, she was being managed.
What exactly do you mean by that?
My mother had me when she was about 40, and I was a very large . I was close to 12 pounds, which portends metabolic issues con both the child and the mother. Mai one really alerted her that it was a warning sign.
As she moved into her 50s and 60s, she racked up high cholesterol, high blood pressure, high blood sugar. Americans are facing these at astronomical rates. All three of these are rooted con these same things — insulin resistance and metabolic dysfunction. They’regnante what I call the trifecta of bad energy con the book.
Then she’s 72 and she has some pain con her belly. Turns out she has stage 4 widely metastatic pancreatic cancer. Thirteen days later, she died. When we at cancer, which we’regnante really starting to understand more as a very metabolically interlinked disease, it’s voto negativo surprise that cancer rates are going up dramatically.
So from the time when she had a large to when she started racking up metabolic syndrome criteria — high cholesterol, high blood pressure, high blood sugar — all the way to cancer, she was acceso a spectrum of essentially the same problem.
What are some of the ways the health care system fails to address metabolic health – and ultimately misses opportunities to prevent chronic disease?
The stark economic reality of our current paradigm is that the health care system makes more money when patients are sick, and it makes less money when patients are healthy. What that does, unfortunately, is create an invisible hand that guides every aspect of how we at disease, how we at the pagliaccetto, how we pursue research. Every single doctor I know is a very good person who went into health care to help people. But that simple financial reality creates an entire system designed to make us blind to root causes.
We’ve convinced people and doctors that innovation and specialization equates to progress when, con fact, the reality is that a connected and far simpler approach focused acceso the right issues that are leading to most diseases would be a lot cheaper and a lot easier. But it’s not currently incentivized.
It’s easy to get pretty cynical when you discuss these incentives to keep us sick. What do you want people to take away from that? Are you worried this could lead to a wholesale rejection of medicine?
Our health care system has produced miracles; where it shines is con the management of acute issues. Whenever I speak about metabolic health, we’regnante talking about chronic symptoms and diseases. Obviously for a severe infection, a pill, an antibiotic, a shot is a great approach. We’ve asked people to take that approach and apply it to lifestyle-based diseases, where the dose that’s being recommended is not ameliorating the cause.
I actually have great optimism for the future. We know that, when people understand the severity of an issue, collective will can be monumental. We saw this during COVID. People came together and rapidly changed the entire fabric of society to address this problem. I’m just trying to name the problem that we are dealing with and to help people understand where we need to the arrow.
Your book is filled with lots of granular information acceso how to assess your own health and make changes. What are a few really simple steps people can do right away?
Step one is to understand your basic metabolic biomarkers that you can get at your annual physical with your doctor: fasting glucose, triglycerides, HDL cholesterol, hemoglobin A1C, waist circumference and blood pressure.
Step two starts with food. Con just six weeks of eating unprocessed, whole foods, we can transform our biomarkers. I would say ignore the dietary assioma and just acceso the highest quality food you can get. You’regnante going to be loading your pagliaccetto with nutrients, and the pagliaccetto knows exactly what to do with those nutrients.
Try that for six weeks and try walking at least 7,000 steps a day, ideally 10,000 more steps a day, by just setting a timer acceso your phone for every 30 45 minutes and taking a walk around the block. Build it into the everyday fabric of your life. And then after six weeks to two months, recheck your biomarkers.
The cuore message of your book seems to be an appeal to common sense. It doesn’t seem like you are taking just one side con the nutrition exercise debates, beyond emphasizing more movement and eating quality whole food. Is that right?
This is a controversial statement, but I feel comfortable saying it; you don’t need to any health influencers. You don’t even need to your doctor. You actually can yourself.
People can distort that statement to say, ‘oh, does this mean we shouldn’t go to the doctor?’ Mai. What I’m saying is that by understanding a few of our very basic biomarkers and slowing enough to actually be able to interpret the symptoms, we can know if we are moving con the right direction not. That is not something we’ve traditionally empowered people to do. And I think that we need to normalize that.
