How to remove the complexity in treating patients requiring medical nutrition therapy

By Michael L. Weinstein, MD, and Hagan Jordan

Nutrition is becoming an increasingly critical form of therapy and an intriguing service line for GI practices across the country. A recent global study published by the Rome Foundation indicated that four in 10 adults have a functional gastrointestinal disorder (FGID)1 and, for most FGIDs, medical nutrition therapy (MNT) is a critical element of the treatment protocol.

GI societies recommend nutrition therapy (i.e., specific dietary protocols) as first-line therapies and complementary treatments in the management of multiple GI disease states, including IBS, IBD, celiac, NAFLD, EoE, GERD, gastroparesis, and general weight loss. These disease states represent a significant percentage of a GI provider’s patient population, which makes adopting an efficient, clinically effective and, ideally, profitable nutrition program important.

Options now exist that enable GI practices to offer nutrition therapy in a way that is clinically effective, operationally efficient, and profitable.

Challenges with Nutrition Services

Most acknowledge the important role of nutrition in GI disease state management. However, nutrition therapies have historically been challenging for GI practices to adopt. Even as great technological advancements have been made in creating systems to make prescribing pharmaceutical drugs and/or performing surgical procedures simpler for physicians, a streamlined, efficient system for managing and achieving positive outcomes for patients with nutrition therapies has been more elusive.

For private practice gastroenterologists in particular, there have been consistent challenges with managing patients that could benefit from nutrition therapy:

1. Time

Most gastroenterologists and mid-level providers don’t have the time to manage these patients. This is because medical nutrition therapies require ongoing coaching and counseling.2 Furthermore, providers aren’t reimbursed adequately to spend the time it would take to “food journal,” find trigger foods, and interface on a regular basis to ensure patient compliance and outcomes.

2. Training

As a general rule, most physicians and mid-level providers don’t have in-depth training on nutrition therapies and specific dietary protocols.3 In a recent survey of 1,500 gastroenterologists, only 56% were “comfortable” to “very comfortable” with providing dietary counseling to their patients.4 Due to this, and the limited time they have with patients, many GI providers offer information and educational materials to help patients adopt recommended diets on their own. Unfortunately, patient compliance is low, and the overall experience is impacted under this self-guided model.

3. Access to a trained dietitian

While data shows GI-trained dietitians significantly improve outcomes for patients needing nutrition therapy and can provide the focused attention and guidance patients need, many GI practices don’t have an established relationship with a local GI-trained dietitian, leading to only 21% of gastroenterologists saying they “usually” or “always” refer their patients to a dietitian.5

4. Economics

The majority of GI practices that have tried to bring nutrition services in-house or hire a dietitian directly have found the economic challenges to be at the forefront. This creates a break-even service line, at best. There are multiple reasons for this but, primarily, lack of insurance coverage, low reimbursement, and low patient willingness to pay out-of-pocket for these services top the list.

These challenges beg a very important question that the GI community has been asking for quite some time:

“How can a GI practice offer a nutrition service line that is clinically effective, efficient, and profitable?”

Let’s start first with a specific disease state/diet example to illustrate the problem and then, of course, a solution.

Case Study: IBS/Low FODMAP

IBS patients present unique challenges for gastroenterologists. The global prevalence of IBS is 10–20% of the population6. However, most GI providers attest to the fact that a much larger percentage of their patient population experiences varying degrees of chronic IBS-like symptoms, such as abdominal pain, gas, bloating, diarrhea, and/or constipation.


Dietary modification, specifically the Low FODMAP diet, is considered a first-line therapy for IBS.7 The Low FODMAP diet is a powerful diagnostic tool to help patients and their providers understand the role that certain foods are playing in their IBS symptoms and, most importantly, identify those specific trigger foods. The protocol significantly decreases and then systematically reintroduces FODMAP subgroups, a collection of short-chain carbohydrates (such as some sugar and fibers), back into the patient’s diet. These foods may not be absorbed properly in the gut and can trigger symptoms in people with IBS. FODMAPs are found naturally in many common foods, even highly nutritious foods, such as wheat, apples, pears, onion, garlic, honey, agave syrup, sugar-free gum, mints, and some medicines.

The goal is to identify the specific FODMAPs that are triggering a patient’s IBS symptoms. Most patients aren’t sensitive to all categories of FODMAPs. Therefore, when they identify their specific FODMAP triggers, they can actually expand or liberalize their diet and better manage their symptoms long-term.

During this protocol, which typically runs six to eight weeks and is not a long-term “diet,” patients go through three specific phases—Elimination, Reintroduction, and Personalization—to identify their specific trigger foods and manage symptoms long-term. Most patients start to experience symptomatic relief in as few as two to three weeks.8

The Low FODMAP diet has been shown to be effective in improving chronic symptoms in up to 86% of patients with IBS.9 Low FODMAP is now the most commonly recommended dietary protocol by gastroenterologists for IBS patients, and 85% of gastroenterologist report Low FODMAP to be somewhat to very effective.10

So, What’s the Challenge?

Like many dietary protocols, the Low FODMAP diet can be challenging for a patient to successfully implement and complete without the support of a trained dietitian or healthcare provider and a system to make food preparation and cooking easier or less stressful for the patient.

In cases where a healthcare provider simply gives the patient a pamphlet or brochure and recommends the Low FODMAP diet, a very small percentage of patients successfully completes Elimination and Reintroduction, and never identifies their specific trigger foods. In fact, a recent study showed only 41% of patients who were recommended the Low FODMAP diet were able to adhere to it through the elimination phase.11 This is a primary reason why only 11% of IBS patients report a positive relationship with their provider and will, on average, visit 5.2 physicians as they seek answers.12

However, clinical data shows outcomes are improved when a patient is:

  1. Connected with an expert dietitian or healthcare provider to coach/counsel them through the Low FODMAP process. Compliance also improves.13
  2. Provided food in some manner to make food sourcing, preparation, and cooking easier.

IBS and Low FODMAP are just one example of a disease state and corresponding nutrition therapy that illustrate the challenges that GI providers face. We could extend these examples into many other disease states requiring medical nutrition therapy. These include NAFLD and Eosinophilic Esophagitis, and see similar challenges.

A Solution to Improve Both Outcomes and Profitability

In early 2019, ModifyHealth launched a new service to make nutrition services more efficient and effective for GI providers and their patients. By partnering with ModifyHealth, GI practices get access to all of the necessary resources needed to provide a world-class nutrition service for their patients without having to build an internal program from scratch and hire a full-time dietitian(s). The GI practice is able to offer a nutrition service program to their patients while also accessing an ancillary revenue stream, if desired.

Starting first with IBS/Low FODMAP. ModifyHealth’s service enables a GI provider to refer their patients directly to ModifyHealth as an extension of their practice. All referred patients have access to a free, initial virtual consult with a GI-trained dietitian. They will receive focused time and attention as well as education, resources, and recipes. The free consult encourages patients to engage with a dietitian to get the support they need. On average, 86% of referred patients participate in the free, initial consult while 40–50% sign-up for the full service with dietitian support and meals.14 The fact that the initial consult is both free and virtual removes barriers to patients getting the help they need.


The full service from ModifyHealth helps to simplify the Low FODMAP protocol and improves compliance. All referred patients receive:

  • A free, initial virtual consultation with a GI-trained dietitian
  • Three additional virtual dietitian consults and ongoing on-demand dietitian support
  • Medically-tailored, Low FODMAP meals delivered directly to the patient’s door
  • A patient-friendly app (iOS, Android) to track progress and connect with their dietitian
  • At the end of the program, the GI provider receives a summary report from the ModifyHealth dietitian

The program is a weekly subscription where the patient purchases affordable, medically-tailored, home-delivered meals (with free shipping). They also pay a one-time $99 fee for all three dietitian consults and on-demand access. For practices that already have a GI dietitian, their patients can simply purchase the meals from ModifyHealth and continue working with their in-house dietitian. The program is very affordable and similar to what a patient is already budgeting and spending on food today, but with the benefit of medically-tailored meals and support.

Clinical Results

The clinical results have been encouraging:

  • 85% of patients who sign up for the program complete the Elimination Phase.
  • 79% of patients report significant relief as defined by at least a 50-point improvement in their IBS-SSS (Symptom Severity Score).
  • The average patient reports a 120-point improvement in their IBS-SSS score.15

In addition to being clinically impactful, ModifyHealth offers an attractive ancillary revenue opportunity where a GI practice can benefit financially. The ancillary program is upon request and not required to refer patients to the service. This ancillary program enables GI practices to add another, new ancillary revenue stream to their practice that is passive in nature and requires no additional infrastructure or new employees. The risk is also minimal for the practice due to no to low upfront costs.
