  • Not Everyone Thrives on High Fiber Diets. This is Why!
    Dec 13 2025
    Thank you Camilla, Marg KJ, Suzette Jensen, Roxy Fort, and many others for tuning into my live video with Chris Miller MD! We went live today with a question that comes up all the time and can make people feel genuinely confused.If fiber is so good for us, why do some people feel amazing when they increase it… and others feel bloated, gassy, inflamed, or just plain worse?Dr. Chris Miller and I unpacked what’s going on, why it’s not “in your head,” and what a smarter stepwise approach can look like.This live was based on Dr. Miller’s most recent article, which I’ll link below along with her Substack and her practice website.The premise: Fiber is still the goal, but the path mattersBoth of us teach fiber. The long-term data is compelling, and in most people a higher-fiber, more plant-forward pattern is associated with better health outcomes.But in real life, we see two very different experiences:Some people increase fiber and get all the “expected” benefits, better digestion, lower inflammation, clearer skin, improved cholesterol, improved blood pressure.Other people increase fiber and get gas, bloating, discomfort, and sometimes signs that inflammation is actually going up.So we asked: what’s different about the second group?The Stanford study that changed how Dr. Miller practicesDr. Miller described a Stanford study published in 2021 that helped explain this divide.Participants were assigned to one of two approaches for about 10 weeks:* High-fiber group: worked up to at least 45 grams of fiber per day from plant foods (vegetables, fruit, legumes, whole grains, nuts, seeds).* Fermented foods group: worked up to about six servings per day of fermented foods.The researchers expected the high-fiber group to have the best microbiome and immune improvements. That is not what happened.What stood out:* The fermented foods group showed a consistent increase in microbiome diversity and a drop in inflammatory markers.* The high-fiber group had mixed results: some improved, some barely changed, and some had increased inflammation and no meaningful rise in microbiome diversity.Even when the groups crossed over, the fermented foods pattern continued to show a strong signal toward lower inflammation.The “why”: You can’t benefit from fiber if you don’t have the gut bugs to use itHere’s the key idea Dr. Miller emphasized.Fiber is not digested by us. It’s digested by our gut microbes.When your gut ecosystem is diverse and functional, fiber gets fermented into helpful compounds (including short-chain fatty acids) that support the gut lining and calm inflammation.But if your microbiome is narrow, damaged, or out of balance, and you suddenly “flood the system” with fiber, you may not have the microbial machinery to process it. The result can be gas, bloating, discomfort, and sometimes more inflammation.So in those people, the smarter move may be:Build tolerance and microbial diversity first, then gradually increase fiber.What narrows the microbiome in the first place?We talked through common reasons gut diversity can shrink over time, including:* Years of low-fiber eating (little to no food reaching the colon for microbes)* Antibiotic exposure* Chronic stress and poor sleep* Environmental exposures and pollutants* Ultra-processed foods and additives that disrupt gut balance* Early-life factors such as C-section delivery and limited microbial exposureThen we widened the lens to practical ways people can support diversity outside of food:Time outdoors, exposure to nature, gardening, travel, interacting with other people, and yes, even pets.Fermented foods help, but not always and not for everyoneThe headline from the study makes it tempting to say, “Everyone should eat a ton of fermented foods.”But Dr. Miller made an important clinical point: some people do not tolerate fermented foods well, especially:* People with autoimmune disease during an active flare* People with histamine intolerance or mast cell activation issues* People with significant dysbiosis who are not ready for that “bioactive load” yetFor those people, the priority is calming the gut and immune response first, then building back up gradually.“Put out the fire before you start planting”This ended up being a central metaphor in our live.If the gut and immune system are inflamed and reactive, the immediate goal is not to force more fiber or fermented foods. The goal is to reduce the reactivity.Dr. Miller talked about strategies that can help people ease in:* Starting with gentler forms of fiber (often cooked, blended, or softened foods before big jumps in raw/high-fiber legumes)* Using anti-inflammatory foods and spices (she mentioned options like ginger, turmeric, and berries)* For histamine issues, using a stepwise plan that may include lower-histamine choices and targeted support, sometimes with medication under physician supervision depending on the caseThe goal is always temporary support to calm things down...

  • The Clock In Your Habits: Why Timing Can Make Or Break Change
    Dec 12 2025

    Ninety days. Two groups. One tiny hip stretch. In this episode, Dr. Laurie Marbas unpacks a surprising study showing that when you do a habit can matter more than what you do — with the morning group reaching “autopilot” seven weeks faster than the evening group, just by aligning with their body clock.

    We explore how your internal circadian rhythm quietly directs everything from hunger and hormones to focus and mood — and how living “off-beat” (late-night scrolling, irregular sleep, all-day snacking) can contribute to what researchers call Circadian Syndrome: a cluster of weight gain, diabetes, high blood pressure, sleep issues, depression, and memory problems.

    You’ll learn:

    * Why habits don’t fail from lack of discipline, but from poor timing and weak cues

    * How your morning cortisol spike can actually help you lock in new behaviors

    * Simple, evidence-informed shifts with light, sleep, and food that make change feel easier, not harder

    * The power of “pre-steps” — like laying out your shoes or dimming lights — to do more work than motivation ever could

    If you’ve ever tried to be “more disciplined” and felt like you were pushing a boulder uphill, this conversation will show you what happens when you finally let your habits sync with your clock instead of fighting it.

  • How to Build Flavor That Heals
    Dec 10 2025

    Thank you Marg KJ, Afsi, Paul k, Michael Galante, Ellen Harrison, and many others for tuning into my live video with Chef Martin Oswald!

    Today, Chef Martin Oswald and I spent time inside the real engine of healthy cooking: flavor. Not gourmet tricks. Not complex recipes. Just understanding how your tongue works, how your brain responds to taste, and how to use spices in a way that makes whole-food meals deeply satisfying.

    We began with heat. If you love Cajun flavors, cayenne is your friend. If you prefer a gentler warmth, reach for chili powders. Spices aren’t just about fire, they’re anchors that create direction in a dish. Once you understand their role, you can build flavor with confidence instead of relying on oils or sugar to carry the meal.

    From there, we explored something essential: the sweet–sour dynamic. Sweetness is the very first taste receptor that fires when food hits your tongue. It’s fast. It’s rewarding. It’s why sugar becomes a familiar shortcut. But instead of eliminating sweetness entirely, the goal is to use it with intention, balancing it with acids like vinegar, citrus, or fermented ingredients so that your food feels bright, layered, and satisfying without drifting into dessert territory.

    We also looked at nut butters as foundational tools. Peanut butter and almond butter behave differently in sauces, and each creates its own flavor base. Depending on what you’re making, one will offer warmth and roundness, the other a lighter, more neutral platform for spices.

    The livestream was hands-on, exploratory, and aligned with the same principles we use in Culinary Healing: start with what you enjoy, understand the mechanics of taste, and practice building flavor patterns that make healthy cooking not just doable but genuinely delicious.

    As promised, this video will stay here for replay. A full article on spices arrives tomorrow, including more guidance on using heat, acid, sweetness, and balance to elevate your meals, and how these simple practices help reinforce your healing habits in the kitchen.

    Thank you to everyone who joined live. Martin and I appreciate your curiosity, your presence, and your commitment to learning how to cook in a way that supports your health. If you do this at home please share how it worked for you. Would you like to see more of this?
