Gut Microbiome

You’re never going to be fully healthy if your gut isn’t healthy. That’s not an exaggeration, it’s biology.

In this episode, I take you back to the 1680s, when a Dutch scientist first looked at bacteria under a microscope (yes, by examining poop, but stay with me), all the way to today’s groundbreaking microbiome research. Because once you understand what’s actually happening inside your intestines, you’ll never look at your gut the same way again.

Here’s what most people don’t realize: the trillions of bacteria living in your gut aren’t just along for the ride. They’re producing 90% of your body’s serotonin and half of your dopamine. They’re running 70% of your immune system. They’re influencing your cravings, your blood sugar, and your belly fat.

So if your gut ain’t happy, ain’t nobody happy.

The good news? You have more control over this than you think.

      The Surprising Possibilities of Getting Older

      Your birthday rolls around every year whether you’re ready or not. But what if aging well had less to do with your age and more to do with your mindset? In this episode of Healthy Looks Great on You, we’re diving into the science of healthy aging and why it’s never too late to start.


      Yale researcher Dr. Becca Levy found that nearly 45% of adults over 65 actually improve in cognitive and physical function over time. The best may genuinely be yet to come, but it depends on two things: your mindset and your lifestyle.

      In this episode, we’re talking about what aging well really looks like, not botox and facelifts. The real stuff like enough energy to hike in the woods, the strength to get up off the floor after playing with your grandkids, and the mental sharpness to win at cards.

      We also tackle the biggest reason most healthy habits don’t stick. And it’s not lack of willpower or discipline. It’s that we’re approaching it all wrong.


      In this episode:

      • Why nearly half of adults over 65 actually get better with age — and how to be one of them
      • How the story you tell yourself about aging directly affects how you age
      • Why fear motivates in the short-term, but doesn’t last 
      • The three things a pastor and a gerontologist both agree make life worth living
      • One simple mindset shift you can start using today

      You’re still living

      If you’re still breathing, you still have a purpose. This episode is your reminder to go live it, as healthy as possible, for as long as possible. Because…

      Healthy looks great on you.

      Eat Beans Without the Bloat

      You know beans are good for you. But if your body has other ideas, keep reading — because there’s a reason this happens, and there’s a lot you can do about it.


      Beans are one of the most nutrient-dense, affordable, longevity-boosting foods on the planet. And yet, “I can’t eat beans” is something I hear all the time.

      You don’t even have to tell me why. I already know. We all learned it as kids.

      Beans, beans, good for your heart…

      Here’s the thing — that little song got it right on both counts. Beans really are good for your heart. And yes, they really are a magical fruit. But that doesn’t mean you have to suffer. In this week’s episode, I’m breaking down exactly why beans cause gas, why that’s not always a bad sign, and eight practical steps you can take to eat more beans without clearing the room.


      Why beans are worth the effort

      Let’s start with the good stuff, because the benefits of beans are genuinely impressive.

      Beans are the seed of a legume — packed with plant-based protein, iron, magnesium, potassium, and both soluble and insoluble fiber. They help stabilize blood sugar, support your immune system, and feed the good bacteria in your gut. They’re a staple food in virtually every culture where people live the longest, healthiest lives.

      The American Heart Association has weighed in too. Research shows that eating legumes four or more times a week — compared to less than once a week — is associated with a 22% lower risk of coronary heart disease. And just one daily serving of beans can reduce LDL (bad) cholesterol by about 5%. That’s meaningful.

      So yes, beans are worth figuring out.


      Why beans cause gas (a quick trip to mini medical school)

      Here’s the deal: it’s the same thing that makes beans so good for you that also causes the problem.

      Beans are full of oligosaccharides — fermentable fibers that your body can’t fully digest on its own. That means they make it all the way down to your colon, where your gut microbiome goes to work fermenting them. Fermentation produces gas. That’s just chemistry.

      But here’s what’s important to understand: that fermentation also produces short-chain fatty acids (SCFAs), which reduce inflammation, support weight management, and feed the beneficial bacteria in your gut — like Lactobacillus and Bifidobacterium. In other words, the gas is a byproduct of something really good happening inside your body.

      That doesn’t make it less embarrassing. But it might make you more motivated to work through it.


      The 8-step “eat more beans” recovery program

      I know that sounds dramatic. But if you’ve been avoiding beans because of the bloat, this is your roadmap back.

      Step 1: Start small. Don’t go straight to a full cup. Try 1–2 tablespoons on a salad or blended into a smoothie. Give your gut microbiome time to adjust before you ramp up.

      Step 2: Use canned beans. This is one of the most budget-friendly, convenient ingredients you can keep on hand. Just drain and rinse them well before using — this helps reduce some of the gas-causing compounds.

      Step 3: Cook dry beans thoroughly. If you have the time, cooking dried beans from scratch is even more economical — just soak them overnight and cook them well. The softer the better. Overcooked white beans are actually amazing blended into gravies and sauces (more on that in the episode).

      Step 4: Slow down and chew. This applies to all food, but especially beans. Thorough chewing starts the digestive process and makes a real difference.

      Step 5: Add the right herbs and spices. Cumin, turmeric, fennel, and curry can all help ease digestion. Fresh or dried ginger is another great option — even ginger tea alongside your meal works well. If you want to get more adventurous, dried kombu (a type of seaweed) is used in traditional cooking to make beans more digestible and adds a nice umami flavor.

      Note: Epazote and asafoetida are also traditionally used for this purpose but are not recommended during pregnancy or when trying to conceive.

      Step 6: Drink more water. The more fiber you eat, the more water your body needs to move it through efficiently. Skip the sparkling water with your bean dish — what fizzes at the top tends to work its way out at the bottom.

      Step 7: Keep eating them. Yes, really. This is the most important step. Your gut microbiome adapts over time. It may take a couple of months, but the more consistently you eat beans, the better your body gets at handling them. Stick with it.

      Step 8: Consider Beano. There is solid evidence that it works. Beano contains an enzyme called alpha-galactosidase that breaks down the oligosaccharides before they reach your colon. The key: take it with your very first bite, not after. It can be a helpful bridge while your system is adjusting.


      One more thing about protein

      Every time I order a meal with black beans, someone asks if I want to add a protein. Black beans have 15 grams of protein per cup — plus fiber, antioxidants, and anthocyanins. That is protein.

      What we actually need isn’t more protein — it’s better quality protein. Plant-based proteins like beans come with fiber and micronutrients, not saturated fat. Your heart, your gut, your brain, and your cholesterol levels will all thank you.

      Insulin Resistance: What to Do When Your Labs Come Back Wrong

      The first time my labs showed signs of insulin resistance, I was convinced it was an error. I exercised regularly. I ate well. This wasn’t supposed to happen to me. So I had them repeated — and sure enough, my numbers were better. Until they weren’t.

      Looking back, that first result was probably my body’s earliest warning that I have a genetic tendency toward diabetes. But even if I’d taken it seriously, I’m not sure I would have known what to do. That’s exactly why I’m writing this today.


      A Little History First

      The first real clue that type 2 diabetes could be reversed came from the operating room. In the mid-90s, researchers observed something surprising in patients who had bariatric surgery — not only were they losing weight, their type 2 diabetes was disappearing, sometimes before they’d lost significant weight. That told researchers something important: this wasn’t just about calories.

      That discovery eventually led to research on whether aggressive dietary changes could produce the same effect. Some of those early approaches were pretty extreme — not exactly something most people could sustain. And that’s been the pattern for decades. People start radical diets, can’t stick with them, and end up back where they started.

      It wasn’t until 2016 that major health organizations, including the WHO, formally accepted that type 2 diabetes is reversible through lifestyle intervention. And it took another five years or so for that idea to really filter into everyday medicine. The good news is we’re there now — and you don’t have to do anything radical to start moving in the right direction.


      Yes, Weight and Exercise Matter — But Stay With Me

      I know. You’ve heard it before. Diet and exercise. But before you click away, let me tell you what that actually means, because it’s probably not what you think.

      Even a 10% reduction in body weight can meaningfully improve insulin resistance. And exercise helps in two ways: it makes your muscles soak up blood sugar even when insulin levels are low, and over time it makes your body more sensitive to insulin overall. Both strength training and aerobic exercise have benefits, but even a short walk after meals makes a measurable difference — and it’s the most doable place to start.

      So yes, put down your fork after dinner and go for a walk. That one habit alone is worth something.


      What to Actually Eat

      There isn’t one perfect diet for insulin resistance, but there are some clear principles.

      Fiber is your best friend. You need at least 30 grams a day, and you can only get it from plants — fruits, vegetables, beans, legumes, nuts, seeds, and whole grains. The more those foods resemble the way nature made them, the better. Multigrain bread on a package label sounds healthy, but it usually just means multiple processed grains. Whole grain means something different — look for that instead.

      Eat in the right order. This one is surprisingly powerful and surprisingly easy. Eat your fiber first — vegetables, beans, nuts. Then protein and fats. Save the simple carbs for last. You don’t have to change what’s on your plate, just the order you eat it. Research shows this can meaningfully reduce your blood sugar response to a meal.

      Fruit is not the enemy. People with insulin resistance are often told to avoid fruit because of the sugar. But whole fruit comes packaged with fiber and polyphenols that actually help counter the inflammatory response to sugar. Studies show that people who eat fruit regularly have a lower risk of developing insulin resistance. Berries, kiwis, and clementines are especially good choices. Just eat them as close to their natural form as possible — a blueberry cobbler doesn’t count.

      Watch your saturated fat. Full fat dairy, red meat, and processed meats like bacon can worsen insulin resistance and interfere with the function of the beta cells in your pancreas that produce insulin. Think of your daily saturated fat intake like a golf handicap — the lower the better.

      Go heavy on plants. A friend of mine had tried everything to get her HbA1c down — her weight was healthy, she didn’t drink, she exercised, slept well, and managed stress. Nothing moved the needle. She shifted to a whole food, plant-based diet — not strict vegetarian, more like 80/20 — and not only did her A1C normalize, her cholesterol dropped significantly too. Most people can’t make a change that dramatic and make it stick. But nearly everyone can make smaller changes that start shifting things in the right direction.


      Don’t Underestimate Stress and Sleep

      This is the part people often overlook. Chronic stress keeps cortisol levels elevated, and high cortisol promotes visceral fat — the kind that collects around your organs and drives insulin resistance. Poor sleep makes this worse by throwing off the hormones that regulate hunger and fullness, leading to cravings that make healthy eating harder. It all feeds on itself in a vicious loop.

      Stress management and restorative sleep aren’t lifestyle extras. They’re part of the treatment. We go much deeper on both inside the Lab, because knowing they matter is one thing — having an actual plan for managing them is where real change happens.


      What Happened When I Put This Into Practice

      My energy improved. My focus sharpened. My productivity went up. My mood stabilized. My skin looked better. And the biggest change of all? My appetite stopped feeling out of control.

      That last one changed everything.


      So Where Do You Start?

      You don’t have to overhaul your life overnight. Start here:

      Add more fiber and eat it first. Take a walk after meals. Get serious about sleep. Find one stress management practice that actually works for you. And if you eat meat, start shifting the balance toward more plants.

      Small changes in the right direction still count as the right direction.
