    Send a text Fiber is everywhere right now. It’s being praised as the answer for gut health, blood sugar, cholesterol, hormones, and weight regulation, often all at once.

    Hydrogen Sulfide SIBO: The Nitty-Gritty of the Tools We Use & Why

    Send a text In this episode, Alyssa takes the conversation around hydrogen sulfide SIBO one level deeper. She shares how hydrogen sulfide SIBO is actually approached in practice, and why jumping ahead, whether to antimicrobials, binders, or protocols, often makes symptoms worse instead of better. Rather than focusing on “what to take,” Alyssa breaks down the sequence that matters: Why clarity has to come before treatmentWhy symptom calming isn’t the same as healing (but still matters)Why motility, bile flow, and timing quietly determine whether progress sticks And why rebuilding the gut too early is one of the most common reasons people relapseAlong the way, she explains why hydrogen sulfide SIBO is so reactive, why some people feel better but flare easily, and why the same tool can help one person while flaring another, depending entirely on when it’s used. Resources mentioned: Read the full blog “Hydrogen Sulfide SIBO: Why Most Approaches Fall Short—and What’s Often Missing.” Download Alyssa’s Low Sulfur Diet guide - a short-term trial to reduce meal-time overwhelm, observe meaningful patterns, and understand whether sulfur is contributing to how you feel.If meals that should feel healthy instead trigger gas, urgency, nausea, brain fog, or a heavy, toxic feeling, hydrogen sulfide SIBO may be part of the picture.

    Why Methane SIBO Causes Weight Gain (Even When Eating Less)

    Send us a text Have you ever looked at your plate and thought, “I’m eating less than ever… so why is my weight going up?” If you’ve tried low-FODMAP, cut sugar and carbs, cleaned up your diet, and somehow feel heavier, slower, and more inflamed, this episode is for you. In this episode, Alyssa dives into one of the most confusing and overlooked patterns in gut health: why some people with SIBO experience weight gain instead of weight loss, and why everything you’ve been told to do might actually be working against you. Alyssa explains why not all SIBO behaves the same, and how a specific subtype can quietly change how your body handles food, energy, and inflammation. You will learn: Why common SIBO advice often doesn’t apply to this patternWhat it means when your body seems to “hold onto” weightWhy digestion can feel heavier and more reactive the harder you tryWhere diet helps, and where it can quietly backfireWhat needs to be addressed for real progress to happenResources mentioned: Download Alyssa’s Methane SIBO Diet Plan - a short-term trial to reduce meal-time overwhelm, observe meaningful patterns, and understand whether methane is contributing to how you feel.DM “GUT CHECK” on Alyssa’s Instagram for a personalized quiz and free meal plans & resources to kickstart your gut healing journey.Check out Alyssa’s FREE Masterclass “Why your gut still isn’t better - the real reason you feel stuck here. Learn more about personalized gut healing plans at Nutrition ResolutionFind Alyssa on: Instagram, LinkedIn, Facebook, Pinterest  - If you’re enduring uncomfortable, painful, and embarrassing GI symptoms and feel like you’ve tried everything, Alyssa uses a specialized approach to help people who’ve gone from doctor to doctor finally find relief.

    Hydrogen Sulfide SIBO: Why Most Approaches Fall Short and How to Fully Address It Naturally

    Send us a text In this episode, Alyssa Simpson unpacks a common yet widely misunderstood subtype of small intestinal bacterial overgrowth (SIBO): hydrogen sulfide SIBO. Many people with this pattern have spent years chasing answers, trying diets like low FODMAP, gluten-free, or low-carb, cycling through symptom management, and being told tests are normal, only to feel worse, confused, or convinced there’s no solution in sight. Alyssa breaks down: What hydrogen sulfide SIBO is and isn’tWhy it behaves differently than hydrogen or methane dominant SIBOWhy symptoms can be unpredictable, systemic, and not limited to the gutHow conventional testing and treatment often miss itHow to think about diet, testing, and targeted functional approachesIf you’ve ever felt like your digestive symptoms just don’t make sense, fluctuating between diarrhea, constipation, bloating, brain fog, fatigue, or body pain, this episode will help you finally connect the dots.

    When Your Body Feels Toxic After Eating: The Sulfur Clue Everyone Misses

    Send us a text Have you tried low FODMAP, gluten-free, dairy-free, or elimination diets and still feel sick after eating? In this episode, Alyssa Simpson breaks down one of the most confusing and misunderstood nutrition strategies in gut health: the low sulfur diet. This is not an episode about cutting out “bad foods” or following another restrictive diet forever. Instead, Alyssa explains why a short, strategic low-sulfur diet trial can be a powerful clarity tool for people who feel deeply unwell after eating, especially those who have already tried low FODMAP, gluten-free, dairy-free, or elimination diets with little to no relief. She walks listeners through what sulfur actually is, why the body normally needs it, and why some people suddenly stop tolerating sulfur-rich foods that are otherwise considered healthy. Along the way, Alyssa shares real client stories that reveal how sulfur overload and hydrogen sulfide activity in the gut can explain symptoms that feel random, cyclical, or impossible to predict. What you’ll learn in this episode: When a low-sulfur diet trial makes sense (and when it doesn’t)Common high-sulfur foods to temporarily reduceLow-sulfur foods that are often easier to tolerate during the trialWhy protein does not need to be eliminatedSupplements that may quietly increase sulfur loadWhy improvement during the trial is a clue, not a diagnosisHow breath testing can help confirm hydrogen sulfide involvementResources mentioned in this episode: Download the free Low Sulfur Diet Guide + 7-Day Meal Plan DM “GUT CHECK” on Alyssa’s Instagram for a personalized quiz and free meal plans & resources to kickstart your gut healing journey.Check out Alyssa’s FREE Masterclass “Why your gut still isn’t better - the real reason you feel stuck here. Learn more about personalized gut healing plans at Nutrition ResolutionFind Alyssa on: Instagram, LinkedIn, Facebook, Pinterest  - If you’re enduring uncomfortable, painful, and embarrassing GI symptoms and feel like you’ve tried everything, Alyssa uses a specialized approach to help people who’ve gone from doctor to doctor finally find relief.
