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.

    Which Sweeteners Are Healthiest? Sugar, Honey, Maple Syrup, Stevia & More

     Which sweeteners are healthiest?  Learn the truth about honey, maple syrup, agave, stevia, monk fruit, and artificial sweeteners—and how they affect your health.Is honey actually healthier than sugar?
    Is maple syrup a better choice?
    What about agave, stevia, monk fruit, or artificial sweeteners?

    If you’ve ever stood in the grocery store wondering which sweetener is the healthiest option, you’re not alone.

    In this episode of Healthy Looks Great on You, Dr. Vickie breaks down the confusing world of sweeteners so you can understand what really matters for your health.

    The average American consumes 17–22 teaspoons of added sugar every day, far exceeding the recommendation from the American Heart Association of 6 teaspoons per day for women and 9 for men. And sugar hides in places you might not expect—from marinara sauce and yogurt to bread and canned vegetables.

    With so many alternatives available today, it’s easy to assume some sweeteners must be better than others. But the truth is a little more complicated.

    In this episode, you’ll learn how different sweeteners affect your body, what counts as added sugar, and how to think about sweeteners in a way that supports better health.


    What You’ll Learn in This Episode

    • What added sugar actually means

    • Why sugar in whole foods like fruit is different

    • How common sweeteners compare, including white sugar, brown sugar, cane sugar, and high fructose corn syrup

    • The truth about “natural” sweeteners like honey, maple syrup, molasses, and agave

    • Whether artificial sweeteners such as aspartame, saccharin, and sucralose are safe

    • Natural zero-calorie options like stevia and monk fruit

    • Why fiber in whole foods helps slow blood sugar spikes and reduce cravings

    You’ll also learn a simple way to think about sweeteners using Dr. Vickie’s Sweetener Ladder, which helps you quickly identify better choices and which ones to limit.


    The Big Takeaway

    When it comes to sweeteners, the goal isn’t finding the “perfect” substitute for sugar.

    The real key to better health is training your taste buds to expect less sweetness.

    When your diet focuses on whole foods—vegetables, fruits, beans, whole grains, nuts, and seeds—your cravings naturally settle down. Fruit begins to taste sweeter, desserts don’t need as much sugar, and your energy becomes more stable throughout the day.

    In other words, the healthiest sweetener strategy isn’t swapping one sweetener for another.

    It’s needing less sweetness in the first place.

    The Secret Weapon to Feeling Better and Looking Younger: The Power of Posture.

    Do you want to look younger, feel more confident, and improve your health without spending a dime?

    There’s a simple habit that can instantly make you appear taller, leaner, and more energized—and most of us stopped thinking about it sometime after childhood.

    It’s posture.

    In this episode of Healthy Looks Great on You, Dr. Vickie takes listeners to mini-medical school (no lab coat required) to explain why posture is one of the most underrated health habits. From breathing and digestion to neck pain, confidence, and core strength, the way you hold your body affects far more than appearance.

    Posture is the sneaky overachiever of healthy habits. It quietly influences how your muscles work, how your spine feels, and even how your brain interprets your energy and mood.

    The best part? You can improve it immediately.


    WHY POSTURE MATTERS MORE THAN YOU THINK

    Most people think posture is about standing up straight or looking polished. But good posture is really about supporting your body from the inside out.

    When your body is properly aligned, several important things happen:

    • Your lungs have more room to expand, improving breathing

    • Your deep core muscles activate automatically

    • Pressure on your neck and spine decreases

    • Shoulder and back tension often improves

    • Digestion may work more comfortably

    • You appear more confident and engaged

    Posture is not about rigidity or standing like a soldier at attention. It’s about dynamic alignment that supports your body as you move throughout the day.


    THE HIDDEN HEALTH PROBLEMS CAUSED BY POOR POSTURE

    Modern life encourages slouching.

    We sit at desks, look down at laptops, and spend hours with our heads bent toward our phones. Over time, this can create a pattern known as forward head posture, sometimes called “text neck.”

    When your head moves forward, the load on your neck increases dramatically. This can lead to:

    • Neck pain

    • Shoulder tension

    • Headaches

    • Upper back discomfort

    • Reduced mobility in the spine

    And surprisingly, posture can even affect sleep quality. Daytime muscle tension in the neck and shoulders often carries over into nighttime discomfort.

    Your neck was not designed to be a phone stand.


    POSTURE AND YOUR CORE MUSCLES

    One of the most surprising benefits of good posture is that it engages your core automatically.

    Deep inside your abdomen is a muscle called the transverse abdominis. It wraps around your torso like a natural support belt and plays a major role in stabilizing your spine.

    When you sit or stand upright, this muscle activates to help support your body.

    In other words, good posture is like passive core training throughout the day.

    You may even notice that when you sit up straight, your abdominal muscles feel firmer and more engaged.


    POSTURE, CONFIDENCE AND YOUR BRAIN

    Your posture doesn’t just affect muscles and joints—it also affects your brain.

    Body position influences how your nervous system interprets stress, energy, and confidence.

    Research shows that sitting or standing upright can:

    • Increase feelings of confidence

    • Improve focus and attention

    • Reduce perceived stress

    • Help you appear more engaged in social situations

    Your posture sends signals to your brain about how you feel. Changing your posture can actually help change the story your brain is telling.


    TRY THIS SIMPLE 3-STEP POSTURE RESET

    Improving posture doesn’t require special equipment or hours of exercises.

    Start with this simple three-step posture reset you can use throughout the day.

    1. Stack
    Align your body so your ears are over your shoulders and your shoulders are over your hips.

    2. Soften
    Relax tension by dropping your shoulders away from your ears, relaxing your jaw, and unlocking your knees.

    3. Breathe
    Take a slow breath in through your nose and a long exhale out.

    That’s it.

    Use this reset whenever you notice yourself slouching—at red lights, during meetings, or whenever you pick up your phone.

    Posture isn’t something you fix once. It’s something you check in with throughout the day.


    SMALL POSTURE HABITS THAT MAKE A BIG DIFFERENCE

    Try building posture awareness into daily routines:

    • Sit tall when you start a meeting

    • Raise your phone to eye level instead of lowering your head

    • Lengthen your spine when you stop at a red light

    • Check your posture when you sit down to eat

    • Take a 60-second posture reset in the afternoon when energy dips

    Awareness—not perfection—is what creates lasting change.


    THE BOTTOM LINE

    Good posture is free, simple, and incredibly powerful.

    It helps you look healthier, feel more confident, support your spine and muscles, and move through your day with more energy.

    Your posture is telling your brain a story.

    Make it a good one.

    And remember—healthy looks great on you.

    GLP-1 Medications: What They Really Do (and Why Lifestyle Still Matters)

    What if weight loss isn’t about willpower—but biology?

    In this episode of Healthy Looks Great on You, Dr. Vickie is joined by Dr. Suzanna Chatterjee, a board-certified OB-GYN and obesity medicine physician, for an evidence-based conversation about GLP-1 medications and metabolic health.

    Together, they take listeners to mini medical school to break down what GLP-1s actually are, how they work in the body, and why insulin resistance—not lack of discipline—is often at the root of stubborn weight gain.

    In this episode, you’ll learn:

    • What GLP-1 medications are and how they affect insulin and metabolism

    • Why weight gain is often a medical issue, not a personal failure

    • How GLP-1s are being used beyond weight loss, including PCOS, infertility, fatty liver disease, sleep apnea, and cardiovascular risk reduction

    • What the research shows about long-term benefits, including reduced all-cause mortality

    • Why muscle, protein, and exercise matter when using these medications

    • What happens when people stop GLP-1s too soon—and how to think about maintenance

    Dr. Chatterjee also explains the concept of weight “set point,” why weight regain is so common, and why GLP-1 medications work best when paired with sustainable lifestyle changes—not willpower alone.

    If you’ve been curious, skeptical, or overwhelmed by everything you’ve heard about Ozempic, Wegovy, Zepbound, and similar medications, this episode brings clarity without hype—and science without shame.
