Diet Masterclass and Q&A

with Dr. Allison Siebecker and Hosted by Shivan Sarna

In this masterclass, you’ll learn about the SIBO diets that work, how to avoid the most common mistakes that lead to misleading results, confusion, or wasted time and money. Whether you’re newly discovering SIBO or you have been battling SIBO (and IBS) for years, this training gives you clarity — the accurate information so you know what to do next.

Here's the other tricky part:

There are at least eight diets commonly used for SIBO.

They all work on the same basic principle: reduce the carbohydrates that bacteria ferment into gas, and your symptoms go down.

Simple enough, right?

Except every single one of these diets still includes carbohydrates. They have to. You can't live on air. So each diet is essentially making its best educated guess about which carbs to keep and which to cut. And some of those guesses are brilliant for you, and some of them are dead wrong for you:,

The carbohydrates that trigger YOUR symptoms depends on:

  • your specific bacterial mix,

  • where those bacteria are camped out in your small intestine

  • how much damage they've done to your gut lining,

  • your enzyme status,

  • even the growing conditions of the vegetables on your plate.

One person's safe food is the next person's worst trigger.

I've seen it thousands of times, and it never stops being true.

So what actually happens is this: you pick a diet, you follow it faithfully, and you get some relief.

Maybe a lot of relief, maybe not enough.

And then you're stuck, because the diet says "eat this, avoid that," but your body is saying something completely different.

The real results, the 75 to 90 percent symptom reduction that SIBO specialists see across roughly 12,000 patients, those come when you stop following any single diet like a rigid rulebook and start customizing it to your own tolerances. That's the piece most people are missing. Not which diet is "the right one." They're all good starting points.

The piece that changes everything is learning how to identify YOUR specific triggers, expand YOUR safe foods, and build a way of eating that actually matches what's happening inside YOUR gut.

That's where the real freedom is.

What exactly is SIBO?

By the way, SIBO is the number one underlying cause of IBS. 

If you’re dealing with bloating, gas, constipation, diarrhea, or that uncomfortable “food just sits there” feeling — and nothing you try seems to fully work — there’s a chance you’re missing a critical piece of the puzzle.

Small Intestinal Bacterial Overgrowth (SIBO) is a condition where certain organisms overgrow in the intestines, interfering with digestion and nutrient absorption, and causing symptoms like altered gut motility and bloating. SIBO is now recognized as a leading root cause behind IBS, chronic bloating, food sensitivities, reflux, and stubborn digestive symptoms that keep coming back.

TYPES:
Small Intestinal Bacterial Overgrowth (SIBO)
Intestinal Methanogen Overgrowth (IMO)
Intestinal Sulfide Overproduction (ISO)

“Thank you for the details on how to get carbohydrates in on the SIBO Diet? I am a runner and training for a half marathon is tough without eating much carbs.”

These are full on Masterclasses, not just a brief overview! I am preparing for my next GI appointment. I have all the wonderful notes to digest, read, absorb and take with me to the appointment. These Masterclasses have already given me several "ah -ha" moments and also give me hope.

Author of Healing SIBO

Shivan Sarna, founder of SIBO SOS® and author of Healing SIBO. After a lifetime of digestive problems, she was diagnosed with SIBO (Small Intestine Bacterial Overgrowth) in 2015. Shivan was so excited to finally have a name for the symptoms that made me miserable – but she was quickly very frustrated by how hard it was to get access to reliable SIBO information, or even an appointment with a doctor who had experience treating SIBO. She set out to get answers about SIBO for herself – but along the way, she met thousands of people who had the same challenges. 

Sound familiar? These questions come up constantly—so we built a class to answer them.

I'm eating "all the right things" and I still feel horrible. What am I getting wrong?

There are so many SIBO diets out there (low FODMAP, Biphasic, SIBO Specific, Elemental). How do I know which one is right for my type of SIBO?

Everything I thought was good for me makes me bloated. What's happening?

How long am I supposed to stay on a restricted diet?

I've been on a SIBO diet for months and I'm terrified to go back to eating normally.

Do GLP-1s impact SIBO?                   

When is it safe to start reintroducing foods, and how do I do it without setting myself back?

What causes sudden, unexplained weight loss or nutrient deficiencies?

What causes chronic diarrhea and constipation together?

Does the diet change during treatment?

I'm following the diet perfectly and still flaring. Is the diet not working, or is something else going on?

Is the Elemental Diet something I should consider, and how do I know if it's the right move for me?
