Working together on gut symptoms means we slow it down, decide whether testing will change the plan, and build a path that brings foods back in instead of cutting more out. Trained in the Monash low-FODMAP protocol and MRT/LEAP.

Gut symptoms make everything harder — work, social plans, sleep, mood. By the time most people reach me, they’ve already cut foods on instinct or tried elimination diets they found online. Together we look at what your symptoms are actually telling us and build a structured plan with a clear path off of restriction.

Who this is for

Recognize any of this in your own gut story?

You’ve been diagnosed with IBS and want a structured plan rather than another round of guesswork.
Bloating, urgency, irregular stools or post-meal discomfort are shaping your day-to-day.
You’ve tried low-FODMAP on your own and either feel stuck on it or aren’t sure how to reintroduce foods.
You suspect histamine-driven symptoms (flushing, hives, headaches, food reactivity) and want a structured, livable approach.
Reflux or GERD is interfering with sleep and meals, and you want strategies beyond medication alone.

How I help

How I work with gut symptoms in practice.

IBS — beyond low-FODMAP

Low-FODMAP is a useful tool, not a forever diet. We use it strategically (when appropriate), then carefully reintroduce foods to find your actual triggers and rebuild a flexible way of eating.

MRT food-sensitivity testing

MRT can help identify foods and chemicals driving inflammation, IBS or fatigue. I’m trained to interpret it and use it as part of a phased plan — never as a standalone ‘avoid these forever’ list.

GI-MAP and functional gut testing

Where the picture is unclear, we may use GI-MAP or similar stool testing to look at gut markers (alongside your physician’s care) and tailor the plan.

Reflux/GERD and low-histamine

Symptom-specific nutrition strategies for reflux, GERD and histamine-driven symptoms — gentle, without over-restriction, and with a clear plan to expand the diet over time.

Nutrition counseling is not a substitute for medical care. Individual results vary.

What’s included

What a gut-focused engagement looks like.

Free 15-minute discovery call to map out the picture and confirm fit.

A personalized plan that may include a structured low-FODMAP or low-histamine phase, GERD-aware strategies, and a clear reintroduction roadmap.
MRT food-sensitivity testing and/or GI-MAP stool testing where it will genuinely personalize the plan — used to personalize, never to diagnose or cure.
Ongoing follow-ups to reintroduce foods, troubleshoot flare-ups and broaden your diet.
Messaging support between sessions for real-life questions (travel, dining out, symptom changes).

“I'd struggled with my PCOS symptoms for years and felt like no one really listened. Working with Leila completely changed that. She took the time to understand what was going on with my hormones and insulin resistance and built a realistic eating plan I could actually stick to - no extreme restriction. Doing everything virtually from home in Yorba Linda made it so easy to keep up with. A few months in and what a night and day difference. Cannot recommend her enough.”

— Linda Defoor

“I started working with Leila when I was living in Orange County and wanted help with nutrition coaching, without another gimmick diet. She built a plan and habit recommendations around real food and my actual schedule, and it finally stuck. When I moved to Texas for work, I figured I'd have to find someone new, but she's licensed there too and everything is virtual, so we could keep progressing. Super convenient. The realistic approach and convenient virtual sessions made it easy to stay consistent. Thanks Leila!”

FAQ

Gut Health & IBS — common questions

Do I need MRT or GI-MAP testing to work with you?

No. Testing is a tool we may use to personalize a plan when it’s likely to change what we do — never a requirement to start. Many clients see meaningful change without any functional testing at all.

Is IBS nutrition counseling covered by insurance?

Often, yes. IBS is a commonly covered diagnosis for medical nutrition therapy. I’m in-network with Aetna in California and provide superbills for out-of-network reimbursement on other plans. Lab fees (MRT, GI-MAP) are typically separate and not covered by insurance.

How long does this typically take?

Most people are in the structured phase for a few weeks, then move into reintroduction over the following weeks to months. The goal is to end on the broadest possible diet — timelines vary based on your symptoms, history and how reintroductions go.

Is this fully virtual?

Yes — every session is virtual, by secure video. I see clients across California, Texas and Nevada. Testing kits ship to your home and are returned by mail.

Do you treat IBD or SIBO?

I don’t treat IBD or SIBO as a primary focus. For those, you’ll want a GI physician and, often, a dietitian with that specific specialty.
