Health Coaching: What Does the Science Say About Ongoing Support and Behaviour Change?


Receiving a treatment plan is one thing. Actually implementing that plan consistently over several weeks or months can be something very different.

Dietary changes, supplement schedules, sleep routines, lifestyle recommendations and follow-up instructions can quickly become difficult to manage in everyday life.

This is one reason health coaching has become an increasingly studied area of healthcare.

Rather than replacing the role of a doctor, naturopath, dietitian or practitioner working in clinical nutrition, health coaching generally focuses on supporting the practical side of behaviour change: setting goals, identifying barriers, monitoring progress, building confidence and helping people implement recommendations consistently.

Research suggests that health coaching may have benefits in several areas, although outcomes vary between populations and the quality of evidence is not equally strong across all studies.


What is health coaching?

Health coaching is generally a collaborative process designed to help an individual work towards health-related goals.

Instead of simply providing more information, coaching may involve:

  • Setting realistic goals

  • Reviewing progress

  • Identifying barriers

  • Problem-solving

  • Building confidence

  • Supporting self-monitoring

  • Helping turn recommendations into practical routines

  • Providing ongoing accountability

This distinction is important.

A naturopath or practitioner working in clinical nutrition may develop recommendations based on an assessment, dietary history, test results and other relevant information.

Health coaching can then provide an additional layer of support around how those recommendations are incorporated into day-to-day life.

What does the scientific research say?

One of the more comprehensive reviews of health coaching was published in Patient Education and Counseling.

The systematic review and meta-analysis included 30 studies examining health and wellness coaching among people living with chronic conditions.

The researchers investigated outcomes including quality of life, self-efficacy, depression and anxiety.

They reported improvements in quality of life, self-efficacy and depressive symptoms at several measured time points. However, the authors also noted an important limitation: the certainty of evidence for many outcomes was rated as low or very low, largely because of differences between studies, risk of bias and imprecision.

That means the findings are encouraging, but they should not be interpreted as evidence that health coaching will produce a particular outcome for every person.

Health coaching and self-efficacy

One of the most interesting areas in health-coaching research is self-efficacy.

Self-efficacy broadly refers to a person's confidence in their ability to perform a behaviour or work towards a particular goal.

This can matter when a person has been given a detailed dietary or lifestyle plan.

Knowing what to do does not necessarily mean that implementing it will be easy.

A systematic review and meta-analysis involving 12 randomised controlled trials and 2,497 participants with hypertension found that health-coaching interventions were associated with improvements in self-efficacy and dietary behaviours within that population.

The researchers also reported changes in blood pressure, although these results relate specifically to people with hypertension and should not be generalised to other conditions or to gut health.

What is particularly relevant from a behaviour-change perspective is that coaching was associated with changes in how participants approached their own health behaviours.

Why implementation matters in clinical nutrition

A clinical nutrition plan can sometimes involve considerably more than being handed a list of foods.

Depending on the person's circumstances, recommendations might involve:

  • Changing meal composition

  • Gradually increasing or decreasing particular foods

  • Monitoring tolerance

  • Following supplement instructions

  • Trialling dietary changes

  • Tracking symptoms

  • Preparing different meals

  • Developing new shopping habits

  • Reviewing progress over time

The scientific literature on behaviour change suggests that ongoing interaction, goal setting, feedback and self-monitoring can be important components of lifestyle interventions.

For example, a 2023 systematic review and meta-analysis examined interventions combining health coaching with smartphone self-monitoring in people with overweight or obesity.

The review included 14 articles involving 2,478 participants.

Compared with control interventions, the combined interventions were associated with changes in several measured outcomes, including body weight, waist circumference and daily energy intake. However, significant differences were not observed for every outcome, including BMI, blood pressure, body-fat percentage, cholesterol and physical activity.

The researchers therefore concluded that further research was needed to determine the additional benefit provided specifically by coaching.

Again, these findings should not be interpreted as evidence that coaching produces weight loss or other outcomes for every individual.

Instead, they demonstrate why researchers are interested in combining ongoing support with self-monitoring and behavioural strategies.


Why ongoing support can be different from another consultation

A consultation with a naturopath or clinical nutrition practitioner may be focused heavily on assessment and clinical decision-making.

Health coaching serves a somewhat different purpose.

A patient may understand their plan but later encounter practical questions such as:

“What do I do if I can't tolerate this food?”

“I forgot how I was supposed to introduce this supplement.”

“My routine changed because of work. How do I make this manageable?”

“I've been following the plan but I'm struggling with one particular part.”

“I don't understand why this recommendation was made.”

These types of practical barriers do not necessarily require an entirely new treatment plan.

Sometimes what is needed is clarification, support, accountability or communication with the treating practitioner.

That is where ongoing coaching can become useful.


The importance of follow-up

Behaviour change rarely happens in a straight line.

People may begin highly motivated and then encounter work commitments, family events, travel, financial pressures or simply difficulty maintaining a new routine.

A rapid systematic review examining whether gains associated with health and wellness coaching could continue after coaching had finished found enough evidence to warrant continued investigation into sustained behaviour change, while also highlighting limitations in the available research and the need for better-designed long-term studies.

This is important because short-term compliance is not necessarily the same as creating a routine that can be maintained.

The objective of coaching should therefore not simply be to tell someone what to do repeatedly.

Ideally, it helps the individual understand the plan, identify obstacles and become increasingly confident in managing the practical aspects themselves.


Health coaching alongside a naturopath and clinical nutrition plan

At The Gut Guy, health coaching is designed to sit alongside the clinical work performed by the treating naturopath and clinical nutrition practitioner.

The different roles are intentionally separated.

The practitioner is responsible for clinical assessment and treatment recommendations within their professional scope.

The coaching component focuses more heavily on:

  • Implementation

  • Clarification

  • Accountability

  • Troubleshooting practical barriers

  • Monitoring how the plan is being followed

  • Helping patients communicate questions back to their treating practitioners

  • Supporting adjustments where clinically appropriate

This allows patients to have support between their major consultations rather than feeling that they have been given a plan and are then expected to manage everything independently.


The Gut Guy Health Coaching & Treatment Adjustment Program

For patients who would like additional support, The Gut Guy offers a six-month Health Coaching & Treatment Adjustment Program for $217.

The program includes:

1:1 support with The Gut Guy himself

Patients have direct one-to-one support with The Gut Guy to help them understand and implement their treatment plan.

This may include discussing practical questions, working through barriers, clarifying recommendations and helping patients organise the different components of their program.

Six months of support

Gut-health programs can involve changes that occur over several months rather than several days.

For this reason, the program runs for six months, allowing support to continue as the treatment plan progresses.

Unlimited support

The program includes unlimited support throughout the six-month period, giving patients somewhere to direct questions that arise between their formal practitioner appointments.

Treatment-plan clarification and adjustment support

If something within the plan is unclear or a patient is having difficulty implementing a recommendation, the issue can be reviewed and, where required, communicated with the treating practitioner so that appropriate clinical adjustments can be considered.

The aim is to create a clearer connection between the treatment recommendation and what the patient is actually able to implement in everyday life.


Does health coaching replace a naturopath or clinical nutrition practitioner?

No.

Health coaching and clinical care are different.

A health coach should not independently diagnose a medical condition, replace appropriate medical assessment or make clinical decisions outside their professional scope.

Likewise, the research discussed in this article does not demonstrate that health coaching treats gastrointestinal disease or that seeing a naturopath or using clinical nutrition will produce a specific health outcome.

The evidence discussed relates to health coaching as a behavioural-support strategy across particular research populations.


Why we include coaching in our model

Our reasoning is relatively simple.

A detailed treatment plan has limited practical value if the patient:

  • Does not understand it

  • Cannot implement it

  • Stops following it

  • Becomes overwhelmed

  • Does not know what to do when circumstances change

  • Has questions but waits months until the next appointment

Health coaching provides a structured way to address these implementation issues.

The scientific literature suggests potential benefits around self-efficacy, behaviour change and some patient-reported outcomes, while also showing that results differ between studies and that more high-quality research is required.

This balanced interpretation is important.

Health coaching is not a guarantee of a particular clinical outcome.

It is a support mechanism designed to help bridge the gap between receiving a recommendation and putting that recommendation into practice.


The takeaway

Healthcare does not stop when the consultation finishes.

For many people, the difficult part begins afterwards—when dietary recommendations, lifestyle changes and supplement schedules have to fit into work, family and everyday life.

Research into health coaching suggests that structured ongoing support may assist with areas such as self-efficacy, health behaviours and some patient-reported outcomes in certain populations, although the quality and consistency of the evidence varies.

When health coaching is used alongside a naturopath, clinical nutrition practitioner or another appropriately qualified healthcare professional, its role can be clearly defined: help the patient understand the plan, work through practical barriers and stay engaged with the process.

At The Gut Guy, our Health Coaching & Treatment Adjustment Program costs $217 and provides six months of unlimited support, including 1:1 support with The Gut Guy himself.

The objective is not to make promises about outcomes.

It is to make sure patients have somewhere to turn when questions arise between consultations.
