CAN'T SLEEP?

You might already know something feels off — you’re tired after meals, craving sugar, carrying extra weight around your middle, or just not feeling like yourself. But here’s something most people don’t know: your blood sugar can look completely normal and insulin resistance can already be working against you.

Insulin resistance isn’t just a precursor to diabetes. It’s a quiet, systemic problem that can affect your brain, heart, kidneys, and eyes — often for years before a single lab value raises a flag. And with over 115 million Americans living with prediabetes, most of them unaware, this is one of the most underdiagnosed health issues of our time.

Here’s the thing — insulin itself isn’t the enemy. It’s actually one of your body’s most important metabolic tools. Think of it like an air traffic controller, directing glucose to your muscles, liver, and cells so your body has the fuel it needs. The problem starts when your cells stop listening.

When the Pancreas Can’t Keep Up

When cells become resistant to insulin, your pancreas does what any responsible organ would do — it works harder, cranking out more insulin to compensate. For a while, it works. Blood sugar stays normal. No symptoms. No diagnosis. But underneath the surface, inflammation and cellular stress are already building.

Eventually the pancreas can’t keep up. Blood sugar rises. Prediabetes sets in. And if nothing changes, type 2 diabetes follows.

The progression is gradual — and largely preventable. That’s why catching it early matters so much.

What You Can Do Starting Today

The good news is that insulin resistance responds to lifestyle changes — sometimes dramatically. You don’t need a complete overhaul. Start with one change:

  • Move after meals. Even a short walk helps your muscles absorb glucose and reduces the burden on insulin.
  • Build muscle. Muscle is one of your body’s biggest glucose sinks — the more you have, the better your insulin sensitivity.
  • Watch what’s around your middle. Waist circumference is one of the most practical indicators of metabolic risk — over 35 inches for women and 40 inches for men increases your risk significantly.

And if you want to know where you stand, ask your doctor about a fasting blood sugar and hemoglobin A1C. Those two numbers can tell you a lot.

Next week we’re answering the question that matters most — can insulin resistance actually be reversed? Subscribe to the newsletter so you don’t miss it.

CAN'T SLEEP?

You might already know what inflammation feels like — fatigue, brain fog, joint stiffness, bloating, or just that general sense of feeling off. But inflammation isn’t just uncomfortable. When it becomes chronic, it silently contributes to some of the most serious diseases of our time: heart disease, diabetes, cancer, and Alzheimer’s.

Here’s the thing: inflammation itself isn’t the enemy. It’s actually one of your body’s most brilliant defense systems. When you get a cut or a infection, your immune system sends in the troops — releasing chemicals that increase blood flow, cause swelling, and promote healing. Short-term inflammation is protective and necessary.

The problem starts when inflammation never fully switches off.

When Healing Becomes Harm

Chronic, low-grade inflammation is more like a smoldering grudge than an acute response. It can quietly damage tissues and organs for years before any symptoms appear. And the triggers are often hiding in plain sight: poor sleep, chronic stress, too much sugar, processed meats, refined carbs, excess alcohol, and a sedentary lifestyle.

Visceral fat — the fat stored deep around your organs — makes things worse by actually secreting inflammatory chemicals called adipokines. This is one reason inflammation and obesity are so closely linked.

What You Can Do Starting Today

The good news is that lifestyle changes have a powerful effect on inflammation. You don’t need a complete overhaul — start with one change:

  • Move after meals. A brisk walk after dinner helps regulate blood sugar and calm inflammation.
  • Add one anti-inflammatory food. Think leafy greens, berries, walnuts, salmon, or olive oil.
  • Prioritize sleep. This one matters more than most people realize.

Sleep is when your body regulates the very immune chemicals that drive inflammation. Without enough restorative sleep, those chemicals overreact — increasing your risk for high blood pressure, heart disease, diabetes, mood disorders, and dementia.

If racing thoughts are keeping you from quality sleep, I have a resource that can help.

CAN'T SLEEP?

Have you ever run your fingers through your hair and discovered it wasn’t as attached as you thought? Hair loss is one of those things that quietly chips away at your confidence — and yet most women never get a real explanation for why it’s happening or what they can do about it.

In this episode, I’m giving you the conversation I wish I’d had with my own patients.


What You’ll Learn in This Episode

  • Why losing up to 100–150 hairs a day is completely normal
  • The 4 stages of the hair growth cycle — and what happens when things go sideways
  • What triggers sudden hair loss (telogen effluvium) versus gradual thinning
  • How hormones — postpartum, birth control, PCOS, and menopause — affect your hair
  • The role of nutrition and which nutrient deficiencies are actually linked to hair loss
  • The truth about biotin, collagen supplements, and whether they’re worth it
  • Which medications can trigger shedding (including an important warning about biotin and your lab results)
  • Alopecia areata, androgenetic alopecia, traction alopecia — what they are and what to do
  • What actually works: minoxidil, Nutrafol, and when to see a dermatologist

Show Notes & Resources

  • Losing 50–150 hairs per day is within the normal range — new growth should keep pace with shedding
  • Telogen effluvium (sudden shedding from stress, illness, surgery, or rapid weight loss) is temporary and usually resolves within 6 months
  • Postpartum hair loss is caused by a drop in estrogen after delivery — it’s normal and it grows back
  • Hormonal changes from stopping or switching birth control, PCOS, and menopause can all trigger hair loss
  • Alopecia areata is an autoimmune condition — see a dermatologist, as newer prescription treatments (including JAK inhibitors) have shown real promise
  • Key nutrients for hair health: iron, zinc, selenium, vitamin D, vitamin A, vitamin B3, biotin, and protein
  • Important: biotin supplements can interfere with certain lab tests, including thyroid panels — always tell your doctor if you’re taking it
  • Excess vitamin A and selenium supplementation can actually cause hair loss — more is not better
  • Topical minoxidil (Rogaine) is available over the counter; low-dose oral minoxidil requires a prescription
  • Nutrafol is a commonly recommended OTC supplement — results vary
  • When in doubt, see a dermatologist — scalp health is their specialty

CAN'T SLEEP?

Get your free guide to turn off your mind and sleep.

When I was in my early thirties, I described my migraines as an ice pick in my temple. Brutal? Yes. Accurate? Absolutely.

I was a practicing OB-GYN. I knew medicine. And yet it took me years to figure out what was triggering my migraines — not because the answer was complicated, but because I wasn’t looking in the right place.

What finally helped me wasn’t a prescription. It was a journal.

In this episode of Healthy Looks Great on You, I’m walking you through everything you need to know about migraine triggers, what to do when a migraine hits, and the practical strategy that helped me go from frequent debilitating headaches to finally feeling like myself again.


What You’ll Learn in This Episode

  • What makes migraines different from regular headaches
  • The four phases of migraine — and what your body is signaling in each one
  • The most common migraine triggers, including several hiding in your pantry
  • Why keeping a migraine journal might be your most powerful tool
  • Natural remedies that can help when a migraine strikes
  • Foods that trigger migraines — and foods that can actually help prevent them
  • Red flag symptoms that mean it’s time to call a doctor

    What Is a Migraine? (And Why It’s Not Just a Bad Headache)

    A billion people worldwide suffer from migraines, making it the third most common disease in the world. Women are three times more likely to be affected than men.

    Migraines are characterized by intense throbbing pain, often accompanied by extreme sensitivity to light (photophobia) or sound (phonophobia). Many people also experience dizziness, nausea, or vomiting. According to the WHO, 40% of adults experience headache disorders — but migraines are in a category of their own.


    The Four Phases of Migraine

    Most people don’t realize that a migraine has four distinct phases, and the headache itself is only one of them.

    1. Prodrome Think of this as the blinking lights at a railroad crossing. You can’t see or hear the train yet, but the warning signs are there — fatigue, mood changes, food cravings, increased thirst.

    2. Aura Not everyone experiences this phase, but those who do may see flashing lights, wavy lines, or blind spots. Some people feel numbness or tingling in their face, or have temporary trouble with speech. It can be alarming — and it’s a signal that a headache is on its way.

    3. Headache This is the ice pick phase. Throbbing pain, light and sound sensitivity, nausea. Migraines can last anywhere from 4 to 72 hours.

    4. Postdrome (the Migraine Hangover) Even after the pain is gone, you’re not quite yourself. Exhaustion, brain fog, and a wrung-out feeling can linger for hours or even a full day afterward.


    Common Migraine Triggers: What to Watch For

    Understanding your migraine triggers is the first step toward preventing them. Here are the most common ones:

    Stress One of the most common migraine triggers — and one of the hardest to eliminate. The goal isn’t to remove all stress from your life (good luck with that) but to manage it so it doesn’t manage you.

    Sleep disruption Insufficient or irregular sleep is a well-documented migraine trigger. Keeping a consistent sleep schedule — yes, even on weekends — can make a meaningful difference.

    Alcohol Red wine in particular is a frequent culprit. Tannins and sulfites in wine, combined with alcohol’s dehydrating effect, create a perfect storm for a migraine.

    Caffeine Paradoxically, caffeine can both relieve and trigger migraines. The key is consistency — drink it in moderate, consistent amounts and avoid sudden changes in your intake.

    Weather changes Barometric pressure shifts are beyond our control, but staying well hydrated can help buffer the effect.

    Medication overuse This one caught me off guard. Taking pain relievers too frequently can cause rebound headaches — a vicious cycle that’s hard to break without recognizing it first.

    Sensory triggers Strong smells (perfume, cigarette smoke, gasoline), bright or flashing lights, and loud sounds can all set off a migraine in susceptible people. I once sat through a handbell choir with a migraine. Never again.

    Intense exercise A hard workout can trigger a migraine, especially if you’re dehydrated or haven’t eaten well beforehand.


    Food Triggers: What to Eliminate First

    Food is one of the most controllable migraine triggers — and one of the most overlooked. Here’s what to watch for:

    • Aged cheeses — contain tyramine, a known migraine trigger
    • Processed meats — hot dogs, salami, and deli meats contain nitrites that can dilate blood vessels
    • Artificial sweeteners — aspartame in particular has been linked to migraines; found in diet drinks and low-calorie products
    • MSG (monosodium glutamate) — found in takeout, packaged snacks, and processed food; always read the back label, not the front
    • Chocolate — a common trigger for many migraine sufferers
    • Fermented foods — high in histamines, which may contribute to migraines in some people
    • Sugar — this was my biggest personal trigger; once a piece of cake started looking like a headache on a plate to me, it got a lot easier to pass on dessert

    Why You Should Keep a Migraine Journal

    Here’s the thing about triggers — yours might be completely different from mine. The only way to find your pattern is to look for it.

    After every migraine, write down:

    • What you ate and drank in the 24 hours before
    • How you slept the night before
    • Your stress level
    • Where you are in your menstrual cycle
    • The weather
    • Any strong smells, sounds, or sensory exposures

    Do this consistently for a few weeks and a pattern will emerge. That pattern is your power.

    My number one trigger was sugar — something no test or scan would have told me. My journal did.


    What to Do When a Migraine Hits

    Even with the best prevention strategy, migraines happen. Here’s what can help:

    Keep a regular schedule Don’t skip meals, maintain consistent sleep and wake times, and keep your caffeine intake steady.

    Thermotherapy Cold causes dilated blood vessels to constrict, which may help with the throbbing. Keep a gel eye mask in the freezer. Lie down, dark, quiet, and cold. Some people find heat on the neck and shoulders with cold on the head helpful.

    Hydration Drink water. Seriously. You can’t control barometric pressure, but you can keep your tank full.

    Breathing techniques Adrenaline is the enemy during a migraine. Try the 4-7-8 method: breathe in for 4 seconds, hold for 7, breathe out for 8. Or try box breathing: in for 5, hold for 5, out for 5, hold for 5, repeat.

    Gentle movement No running in the hot sun. But slow, intentional movement like yoga or tai chi can calm the nervous system and relax the body.

    Pressure points and massage Massaging your temples is a natural instinct for a reason. Over-the-counter ointments with camphor and menthol like Tiger Balm may also help.

    Aromatherapy Lavender and peppermint oil are worth a try.

    Ginger tea Helpful for nausea and easy to keep on hand.


    Foods That Can Help Prevent Migraines

    Just as some foods trigger migraines, others can help prevent them. Foods rich in magnesium are particularly beneficial:

    • Dark leafy greens — spinach, Swiss chard, kale, arugula, collard greens
    • Potatoes with the skin on
    • Artichokes

    Magnesium supplementation (typically 400–500mg of magnesium glycinate) is also one of the most evidence-backed preventive strategies for migraines and worth discussing with your physician.


    When to See a Doctor

    The remedies above are for your typical migraine. But some symptoms require immediate medical attention:

    • Sudden, severe headache that is the worst of your life
    • Headache with fever, confusion, stiff neck, or seizures
    • Headache with weakness, numbness, or vision changes you haven’t experienced before
    • Headache after a head injury

    Don’t ignore these. Call your doctor or seek emergency care.

    And if you’re having migraines more than four days a month, that’s a conversation worth having with your physician about preventive treatment options.

    CAN'T SLEEP?

    When Dr. Vickie was 26 years old, sitting in a hospital cafeteria surviving on hamburgers and Coca-Cola, she got her first cholesterol result back: 256. High cholesterol runs in her family — so she wasn’t shocked. But she was paying attention.

    Decades later, she lowered her own cholesterol by 100 points through diet and exercise alone — something her doctors once said was barely possible. Now she’s bringing that personal experience together with the brand new 2026 cholesterol guidelines to help you understand your risk and what you can actually do about it.


    What You’ll Learn in This Episode

    Cholesterol isn’t the villain it’s been made out to be — your body needs it. But when levels in the bloodstream get too high, the risk to your heart and blood vessels is real. Dr. Vickie walks you through the science simply and clearly, covering everything from how cholesterol is made in the body to what the latest guidelines say about treatment targets.

    You’ll come away knowing how to find your personal 10-year heart disease risk using the PREVENT calculator, what your LDL number should actually be based on your individual risk level, and why fiber and saturated fat matter far more than whether you eat eggs. She also takes an honest, myth-busting look at statins — including the real side effect profile, the misinformation that has made people afraid of them, and when they genuinely make sense.


    The Bottom Line on Diet

    Saturated fat raises bad cholesterol. Fiber lowers it. That’s the foundation. Beyond that, unsaturated fats — found in avocados, nuts, olive oil, and fish — can actually raise your good cholesterol. And if you’re looking for a dietary pattern with the most evidence behind it for lowering LDL specifically, Dr. Vickie introduces the Portfolio Diet alongside the better-known Mediterranean diet.


    What About Statins?

    If you’ve heard that statins cause dementia, or that doctors prescribe them to make money, this episode is for you. Dr. Vickie addresses both claims directly — and explains what she would personally do if her own doctor ever recommended one.

    Three Simple Strategies to Sleep Better

    Download your free cheat sheet to start sleeping smarter tonight.

    When colds, flu, RSV, and COVID-19 spread

    Ever been sitting next to someone coughing and sneezing who assures you, “Don’t worry, I’m not contagious”?

    In this episode of Healthy Looks Great on You, Dr. Vickie takes listeners to mini medical school to answer a question many people misunderstand: how do you actually know if you’re contagious?

    Upper respiratory infections like the common cold, influenza, RSV, and COVID-19 are among the most contagious illnesses we encounter. They spread easily through coughing, sneezing, and even contaminated surfaces. And one of the biggest challenges is that people often spread these viruses before they realize they’re sick.

    Understanding when you are contagious can help protect the people around you—especially babies, older adults, and anyone with a weakened immune system.

    Fever isn’t the only sign that you’re spreading germs.

    In This Episode You’ll Learn

    • When colds, flu, RSV, and COVID are most contagious

    • Why you can still spread illness without a fever

    • How to tell the difference between allergies and a viral infection

    • Why antibiotics don’t work for colds and most bronchitis

    • What makes RSV particularly dangerous for infants and older adult

    When Are You Contagious?

    Many people assume they’re only contagious if they have a fever. In reality, most respiratory viruses spread through coughing, sneezing, and respiratory droplets, even when fever isn’t present.

    Symptoms that suggest you may be contagious include:

    • coughing

    • sneezing

    • runny or congested nose

    • sore throat

    • fatigue or body aches

    In fact, many viral infections become contagious one to two days before symptoms begin, which is why illnesses spread so quickly through households, workplaces, and schools.

    Why Antibiotics Usually Aren’t the Answer

    Most upper respiratory infections are caused by viruses, not bacteria. That means antibiotics won’t treat the illness and can actually cause harm when used unnecessarily.

    Taking antibiotics when they aren’t needed can disrupt the gut microbiome and contribute to antibiotic resistance, making infections harder to treat in the future.

    Understanding when you may be contagious is one of the simplest ways to keep your family and community healthier.
