#27: Does Walking Improve Metabolism? Why Simple Daily Movement Outperforms Supplements

Walking improves metabolic health, blood sugar regulation, cardiovascular health, and longevity. In this episode of The Vitality Formula, physician Dr. Marie Livesey explains why simple daily movement often outperforms supplements for long-term health. While wellness culture often emphasizes supplements and complex routines, research consistently shows that simple daily movement particularly walking can significantly improve metabolism, cardiovascular health, mood, and long-term health outcomes.

Dr. Livesey explains what actually happens inside the body when you walk and why this accessible form of movement influences multiple systems at once, including insulin sensitivity, cardiovascular function, stress hormones, and energy regulation. She also discusses why busy professionals often overlook foundational physiology while searching for more complicated health solutions and how walking can realistically fit into demanding schedules.

Most people I work with are busy professionals, leaders, parents, business owners, entrepreneurs, people whose calendars often feel like a game of 4D Tetras. And when their health and energy levels start declining, the first instinct is to look for the most efficient solution possible. And I don't blame people. They're so busy. Given the choice to prescribe them one intervention that improves blood sugar, mood, heart health, sleep quality, cognitive performance, and longevity, it would not be a supplement or most medications. It would be walking. Yes, I know. Very unsexy and inexpensive advice in a world that loves things to be costly and complicated. Hello, and welcome back to the Vitality Formula. I'm your host, Dr. Marie Livsey, physician, metabolism and hormone health expert, and founder of Lively Holistic Health. I help busy professionals take back control of their health, metabolism, and weight in ways that actually fit real life. And today we're talking about something that might sound deceptively simple because it is walking. More specifically, the uncomfortable truth that walking solves more health problems than supplements and even many medications can. Now, before anyone panics, let me be clear, I am not an anti-medication person, and this is not an anti-medication episode. Medications absolutely have an important place in medicine. I prescribe them to my patients regularly when indicated, and I personally take medications daily that are prov prescribed, I can't talk, by my healthcare provider. But I have noticed that we have developed a cultural habit of overlooking the underlying physiology and causes to diseases while chasing much more complicated solutions. So today we're going to unpack why walking has such a powerful metabolic effect, what actually happens inside your body when you walk, why it outperforms many supplements, and how busy professionals can realistically integrate it into daily life. Because sometimes the most powerful health interventions are the least glamorous, though you can make literally anything glamorous with a matching set from Lululemon. I do not think it is a secret that industry loves complexity. Simple solutions are more difficult to sell and they are less profitable. Supplements and medication commercials make them look so cool while condensing the side effects into this five-second super fast talking ramble where you hear like diarrhea and then death, and that's it, nothing else. And having a multi-step morning routine, it just feels productive to be able to check things off a list. Say you did all of these things, and as achievers, we, yes, we, myself included, we love that feeling of productivity. But go for a walk. If your doctor, a commercial, a sponsored post on Instagram said, tired, just go for a walk. You'd be insulted. You'd feel dismissed, probably file a patient complaint, and definitely keep on scrolling. Walking isn't just a fringe or trending wellness idea. There are literally thousands of studies on walking and health, including large analyses pulling dozens of trials and populations with tens of thousands of participants. Walking consistently shows benefits for heart health, blood sugars, mental health, and longevity. If walking were a pharmaceutical drug, the amount of research supporting it would make it one of the most evidence-backed interventions in medicine today. Now, a brief intermission for some statistics, because if you have been here for any length of time, you know that I love to include data and reference the source so you A, know that I am not making up random crap to sound cool and smart, and B, so you can look into it yourself if you want to go deeper. A prospective cohort study in the Lancet followed 5,000 adults for about 10 years, and they found that people walking around 8,000 steps per day had roughly half of the death risk compared to those walking 4,000 steps per day. Another sizable study was a meta-analysis in JAMA of over 34,000 adults, and they found that walking speed alone is a strong predictor of survival. Hmm, maybe if we can speedwalk, outspeedwalk the dino. I summarized this one as walk faster, live longer. In the Harvard Nurses Health Study, this was a large prospective cohort with more than 70,000 women. Those who walked about three hours per week had around a 35%, 35% lower risk of heart disease. And then finally, the BMJ did a large network meta-analysis, analyzing more than 300 trials involving over 300,000 participants, and found that exercise interventions can be as effective as drug therapy in reducing mortality, aka death for some chronic diseases. If that doesn't convince you to start walking more, I do not think that anything will. So what does walking actually do inside your body? When you walk, multiple physiologic systems begin working together. And this is where things get interesting. Walking is one of the most effective ways to improve your blood sugars after a meal. After you eat the glucose, aka sugar rises in your bloodstream. When we walk, our muscles contract, and that allows glucose to enter our muscle cells without requiring as much insulin. This improves our insulin sensitivity because less insulin is required to manage our sugars, because that sugar is going into muscle cells, and that reduces the strain on your pancreas. It also reduces fat storage because high insulin levels are going to dry fat storage, particularly in the liver and the abdomen, that visceral fat that you hear about, that bad fat. And then having less insulin around also allows our bodies to use stored energy instead. Studies have shown that even a five to 10 minute walk after meals significantly reduces blood sugar levels, though most benefits are found around that 30-minute mark, which means a short walk after dinner can have a larger metabolic impact than many supplements, berberine, that are marketed for blood sugar support. So, what does it do, this walking for our heart and our blood vessels? Walking also improves that lining of our blood vessels called the endothelium. It's going to help and it's going to reduce our blood pressure. It's going to improve our circulation and it's going to help our cholesterol, driving that HDL, our good cholesterol up and our LDL down. And regular walking has been associated with lower LDL levels, improved HDL, and a reduced cardiovascular risk. Walking also influences several key hormones involved in metabolism and mood. It regulates cortisol, the stress hormone you always hear about, insulin, which we just reviewed, appetite by making the body more sensitive to leptin, the satiety hormone. And generally, walking doesn't increase ghrelin, that hunger hormone, where more intense exercise tends to do so. And then our serotonin and dopamine pathways, walking helps increase both of these, which helps our mood. Many of my patients are dealing with chronic stress, and walking functions as a gentle nervous system reset, which matters so much more than most people realize, because a dysregulated stress response disrupts our sleep metabolism and appetite. And something as simple as walking helps bring that system back to a more regulated state. So why did I make that outlandish claim that walking often outperforms supplements? Number one, walking is free and impacts so many systems at once. The supplement stacks I often see recommended to people are$100 to$200 per month. And I don't know anybody who walks casually for health reasons who goes through a good pair of sneakers per month. So walking is going to be cheaper and is technically free. Number two, the effects of walking are cumulative. When you take supplements over time and then you stop taking them, the effects are no longer there. Number three, many supplements like magnesium, berberine, fish oil, and vitamin D modulate many pathways that walking has measurable effects on. So these supplements, they modulate, they, they um, what's a good way to put it? They they interact with a lot of systems. It's not to say that, like, oh, magnesium only works on one pathway, fish oil only works on one pathway because that wouldn't be true. But the effects of walking on our different pathways, we can measure. And this is why walking is a foundational habit. I encourage all people to develop because it sets you up for success and it creates ripple effects across multiple areas of health. Particular patient comes to mind here. They are Italian in their 50s, and labs on annual screening showed diabetes. The A1C was 7.8. There was a high LDL, that bad cholesterol, and a low HDL, that good cholesterol. This patient straight up was like, I'm from New York. I am not going to give up bagels, and I am not going to stop eating pasta or butter, and I am not gonna take medication. If you can imagine my face, not even a mask could have hidden that. And I was like, uh, okay. And after a long pause, as a girl who grew up in Jersey, I get the bagel thing. So I said, can we at least try to go for half? To which they acquiesced. And then I was like, okay, well, I guess this means the only thing I can encourage you to do from here and help you change is exercise. If diet's not going to change, if medicines aren't gonna be added, if you do nothing else, please try to walk 20 to 30 minutes a day, is what I told this patient. And if you come back and your blood sugars aren't good, they don't look good, we will have to readdress this issue and discuss starting a medication. The patient followed up in three months as instructed, and the A1C went from 7.8 to 6.8, which technically is considered control for diabetics on medication. So I was pleased. I asked the patient what they had changed, what they had done, and they said, I walk a mile almost every day. That was it. With walking, we were able to improve this patient's health while respecting their priorities, bagels and pasta, and wishes not to take medication. One of the biggest barriers to health habits that I see and hear about all day is the perceived time that is going to require. Perceived. Many people believe that exercise only counts if it involves an hour at the gym, intense workouts, or a long run. But walking integrates easily into real life. My patients will take the long way back to their office from the bathroom because they work in this very large five-sided building. They will sneak out for 10 to 20 minutes and walk the stairs in the parking garage, and others will leave a few minutes early for a meeting so that they can take the long way and make sure they take the stairs. Sure, the guidelines say that moderate exercise should be for at least 30 minutes at a time, five days a week, but for a lot of people that is a steep entry barrier when they are leaving their houses at 5 a.m. to be traffic. It is so much easier for me to convince someone to go for a five-minute stroll after dinner than a 30-minute power walk when they're absolutely exhausted. We all have to start somewhere, and something small consistently is always, always going to be better than inconsistent intensity. If you want to leverage walking for metabolic health, here are a few simple strategies. Number one, walking after meals. We already talked about how this is going to help with blood sugar control. Number two, aim for movement, not perfection. What if instead of chasing that 10,000 steps right away, right out of the gate, because that has been set as some arbitrary standard, what if you started by increasing your baseline movement? If you're currently only getting 3,000 steps a day, your goal should be to get around 4,500 steps for the next month. You will still see metabolic benefits and you are more likely to stick with this long term because you are going to feel successful and feel that success the more frequently you hit that goal. And when you feel that success, that's going to fuel you, fuel you to keep going. Number three, use walking as a stress regulation tool. Walking outside, especially in natural light, helps us regulate our sleep wake cycle and our nervous system. It was funny, last week a patient's parent was talking to me about their nine-month-old not sleeping through the night, but noted the days that they spend a lot of time outside. The sleep is always better. And while the majority of people that I care for are not infants, this applies to all age groups. For people dealing with high stress, walking and spending more time outside can improve both sleep and mood. And finally, number four, stack walking into existing routines. I like to think of walking less as exercise and more as a part of a daily rhythm. For my work from home beeps, 20 minutes in the morning after breakfast and another 10 minutes later in the day. For my commuters, 10 minutes after lunch, 10 minutes when they get home to give them space between that horrible commute and their home life, and then 10 minutes after dinner. It only has to feel like exercise if you want it to. If you spend enough time in the health and wellness space, it can start to feel like the next supplement, medication, technology, pair of shoes is always the answer. But many of the most powerful interventions remain incredibly simple. Walking, sleeping, eating real food, and finding ways to manage stress. These are not glamorous solutions, but they are effective ones and inexpensive. Sometimes the most radical health decision you can make is ignoring all of the noise out there and choosing simple, choosing consistent over intense, and choosing to not let it be complicated.
