Episode 233: The Gut Microbiome: Your Key to Health

This episode can change how you think about your plate, because what you eat is connected to a community of organisms doing quiet, important work inside your body every single day. Your gut microbiome is the key to health. 

🎧 Listen now, and if you’re ready to take what you learn here and actually put it into action, the Gut Health Lab opens July 1st. It’s a 3-month cohort where we’ll nourish our microbiomes together, because healthy looks great on you.

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.

🎧 Listen now, and if you’re ready to take what you learn here and actually put it into action, the Gut Health Lab opens July 1st, 2026.

It’s a 3-month cohort where we’ll nourish our microbiomes together.

Because healthy looks great on you.

    Tame Your Appetite Without Willpower

    Do you find yourself raiding the pantry at 9 p.m. even though you’re not really hungry? In this episode of Healthy Looks Great on You, Dr. Vickie breaks down the science of appetite and gives you a practical, food-based strategy to finally get it under control.

    You’ll learn:

    • The difference between true hunger and emotional eating (boredom, loneliness, habit)
    • How your hormones, including GLP-1, ghrelin, leptin, and insulin control your appetite
    • Why calorie restriction often backfires and leads to weight gain
    • The four foods that naturally suppress hunger: soluble fiber, protein, healthy fats, and fermented foods
    • Why 90 – 95% of Americans are fiber deficient and what that has to do with belly fat

    Dr. Vickie also shares a surprising stat: a 10 gram daily increase in soluble fiber is linked to a 3.7% decrease in visceral belly fat over five years. And she’s inviting you to put it to the test with a free 7-Day Fiber Challenge starting May 26th.

    The holidays are over, the decorations may still be up, and you’re finally catching your breath—only to realize you’re exhausted, overwhelmed, and wondering when belly fat decided to move in permanently.

    In this episode of Healthy Looks Great on You, we talk about why overwhelm isn’t just mental—and how stress, disrupted sleep, holiday eating, and aging hormones all contribute to stubborn belly fat. You’ll learn why fat redistributes to the midsection as we get older, why willpower alone doesn’t work in January, and how overwhelm can quietly sabotage even the best intentions.

    We’ll also cover why belly fat is more than a cosmetic issue, how small lifestyle changes can shift hormones in the right direction, and where to start without feeling like you need a total life overhaul.

    If you’re ready to tackle belly fat in January with practical, science-backed strategies and supportive accountability, I’ll share details about The Lab—a private community designed to help women create real, sustainable change without overwhelm.

    Because healthy looks great on you—and it starts with one small step.
