The Perspective, published in the JAMA Network on 1 October 2026, urges clinicians and health systems to build multimodal management of obesity that extends well beyond pharmacological treatment. According to the authors, effective care must integrate screening, early management, and intensive behavioral therapy across the entire life course. The argument is not a rejection of GLP-1 therapies, which the authors implicitly recognize as a powerful new tool, but a warning against treating them as a complete solution. Obesity, they contend, requires the same kind of comprehensive, long-term clinical architecture that other chronic diseases have demanded for decades.

The scientific rationale for this position rests on the biology of obesity itself. Body fat mass is regulated by a network of hormonal, neural, and behavioral feedback loops centered on the hypothalamus, the gut, adipose tissue, and the reward circuits of the brain. GLP-1 receptor agonists intervene at one crucial node of this network: they mimic an incretin hormone released after meals, slowing gastric emptying, enhancing satiety, and reducing appetite through both hypothalamic and higher-order neural pathways. Newer agents add glucose-dependent insulinotropic polypeptide activity, further improving metabolic outcomes. The results in randomized trials have been striking, with double-digit percentage losses of body weight now achievable pharmacologically for the first time.

But the same biology explains why medication alone is structurally insufficient. Obesity is characterized by adaptations in energy homeostasis that defend body fat stores. When caloric intake falls, whether through diet, surgery, or drugs, compensatory mechanisms increase hunger, reduce satiation, and lower resting energy expenditure. Trials of GLP-1 therapies have shown that discontinuation is typically followed by substantial weight regain, a pattern consistent with the rebound observed after intensive lifestyle interventions and bariatric surgery. The disease process persists beneath the treatment effect, which is why the Perspective frames pharmacotherapy as one component of a durable management strategy rather than a cure.

This is where the multimodal model becomes central. The authors call for systematic screening so that obesity and its early metabolic disturbances are identified before they progress to established comorbidities such as type 2 diabetes, cardiovascular disease, nonalcoholic fatty liver disease, obstructive sleep apnea, and several obesity-associated cancers. Early management, in their framing, means intervening at the stage when lifestyle change and modest pharmacological support can alter trajectory most effectively, rather than waiting until advanced disease leaves fewer options. Screening also carries an equity dimension, because obesity prevalence and access to care vary sharply across socioeconomic groups and regions, and late diagnosis tends to concentrate in populations with the fewest resources.

Intensive behavioral therapy forms the third pillar. Decades of research, including the landmark Diabetes Prevention Program, have established that structured programs combining dietary change, physical activity, and behavior modification can produce meaningful weight loss and reduce progression to type 2 diabetes, even before modern drugs existed. The Perspective argues that these interventions should not be displaced by pharmacotherapy but combined with it. Behavioral support addresses the skills, environment, and psychological factors that determine whether initial weight loss is maintained, and it remains the component of care that patients continue to control after any prescription ends. In a health system organized around multimodal care, a patient beginning a GLP-1 medication would simultaneously receive nutritional counseling, physical activity guidance, and structured follow-up designed to outlast the treatment period.

The life-course emphasis of the Perspective adds a further layer of urgency. Obesity develops through interactions of genetics, early-life nutrition, environment, and behavior, and its consequences accumulate across decades. Adiposity established in childhood and adolescence tracks strongly into adulthood and raises the lifetime burden of cardiometabolic disease. At the other end of the age spectrum, older adults face the dual challenge of excess fat mass and loss of lean muscle, making weight management strategies that preserve muscle and bone particularly important. A therapy-centered model that ignores these developmental windows, the authors suggest, will systematically miss the points of maximum leverage.

The comorbidity dimension is equally consequential. Obesity rarely travels alone; it clusters with hypertension, dyslipidemia, insulin resistance, chronic kidney disease, and mental health conditions including depression, and it multiplies the clinical complexity of each. Interestingly, some GLP-1 and related agents have shown cardiovascular and renal benefits in dedicated outcome trials, suggesting that the pharmacological era may deliver dividends beyond weight itself. Even so, the Perspective’s central claim stands: managing the comorbidities of obesity requires coordinated clinical attention to each condition, integrated screening protocols, and care pathways that treat the patient as a whole rather than a prescription target. Multimodal care, in this vision, is as much about health-system design as about individual treatment choices.

The timing of the argument reflects a real-world inflection point. Health systems are currently absorbing the consequences of explosive GLP-1 demand: shortages, questions about lifelong therapy costs, insurance coverage debates, and a growing population of patients who begin these drugs without any accompanying behavioral or nutritional support. Clinical guidelines from major professional societies already recommend that pharmacotherapy be combined with lifestyle intervention, but implementation has lagged, driven by cost, workforce limitations, and fragmented reimbursement. The Perspective effectively functions as a policy signal, urging that the infrastructure of obesity care, from primary care screening to structured behavioral programs, be built in parallel with drug access rather than as an afterthought.

What emerges from the JAMA Perspective is a pragmatic synthesis rather than a rejection of the pharmacological revolution. GLP-1 therapies have removed one of the most discouraging barriers in obesity medicine, the limited efficacy of available drugs, and they deserve a central place in treatment. But the disease they treat is chronic, adaptive, and woven into behavior and environment across a lifetime. The authors’ prescription is correspondingly broad: screen early, intervene early, deliver intensive behavioral therapy, combine these elements with medication where appropriate, and sustain care across the life course. If health systems follow that blueprint, the GLP-1 era may be remembered not as the moment obesity was medicated, but as the moment its comprehensive management finally became possible.

The study, conducted by researchers at Public Health Wales alongside collaborators, focused on a service developed by Cardiff and Vale University Health Board, one of seven health boards within NHS Wales. Prehab2Rehab is a personalised, multimodal intervention designed to support eligible cancer patients before their treatment begins. Rather than addressing a single dimension of health, the programme simultaneously targets three pillars: exercise, nutrition and mental wellbeing. Staff working within the service tailor the intervention to each individual, aiming to improve patients’ lifestyle behaviours and, in turn, their physical and psychological resilience ahead of surgery, chemotherapy or radiotherapy. The underlying logic is straightforward but powerful: a fitter, better-nourished and psychologically steadier patient is better equipped to tolerate aggressive treatment and to recover from it.

To understand how the programme performs in practice, the research team adopted a mixed methods design, with the published paper presenting the qualitative strand of the evaluation in depth. Between April and November 2024, the researchers carried out semi-structured interviews with fourteen members of staff, including those working directly on Prehab2Rehab and others involved in the wider cancer pathway, and fifteen patients who had first-hand experience of the programme. The interviews were analysed using inductive thematic analysis, an approach that allows themes to emerge from the data itself rather than being imposed by a pre-existing framework. The researchers then triangulated these interview findings with secondary data collected by the Prehab2Rehab team, which provided an overview of programme attendance, strengthening the credibility of the conclusions.

The headline finding is encouraging. Most patients who took part in the evaluation found the programme feasible and acceptable, and reported positive experiences overall. The majority of interviewed patients felt that the exercise and diet support and guidance had helped them make genuine improvements to their lifestyle. Before starting treatment, participants reported improved knowledge and confidence to be physically active or to improve their nutrition. In a health system where the interval between diagnosis and treatment can feel like an anxious limbo, the idea that patients can use that time to actively prepare their bodies represents a meaningful shift in the philosophy of cancer care, from passive waiting to active preparation.

One of the most striking findings concerns the role of peer support. Patients reported benefiting from meeting other people going through similar experiences, connections they made through Prehab2Rehab. The psychological value of this should not be underestimated. A cancer diagnosis can be an isolating experience, and the opportunity to share fears, practical tips and encouragement with others on the same pathway appears to have added a dimension to the programme that goes beyond its formal exercise and nutrition components. This suggests that the social architecture of prehabilitation programmes may be as important as their clinical content, a lesson that could inform the design of similar services elsewhere.

However, the evaluation also exposes an uncomfortable truth about equity in prehabilitation. Patients with more available time, stronger social support networks and better baseline physical capacity were able to engage more fully with the programme. In other words, those who arrived with greater resources, whether temporal, social or physical, extracted more benefit from the service. This pattern raises important questions for policymakers and clinicians. If prehabilitation disproportionately helps those who are already better positioned to help themselves, there is a risk that the intervention could widen rather than narrow inequalities in cancer outcomes. The findings suggest that programmes like Prehab2Rehab may need to build in additional scaffolding, such as flexible scheduling, transport support or adapted activities, to reach patients who face barriers to engagement.

The technical logic behind prehabilitation rests on well-established physiological principles. Cancer treatments, particularly major surgery and systemic therapies, impose significant physiological stress on the body. A patient’s cardiopulmonary fitness, muscle mass and nutritional status at the point of treatment are strong predictors of complications, treatment tolerance and recovery speed. Exercise interventions in the pre-treatment period can improve aerobic capacity and muscular strength, while dietary optimisation can address the malnutrition and weight loss that many cancer patients experience. Psychological support, meanwhile, can reduce anxiety and depression, which are themselves associated with poorer adherence to treatment and worse recovery. Prehab2Rehab’s multimodal design reflects this evidence base, attempting to intervene on all three fronts simultaneously rather than in isolation.

The process evaluation methodology itself deserves attention. Unlike a randomised controlled trial, which asks whether an intervention works under ideal conditions, a process evaluation asks how an intervention is actually delivered, received and experienced in the messy reality of routine care. This distinction matters enormously for health services trying to scale up innovations. A programme can have strong trial evidence yet fail in practice if referral pathways are unclear, staff capacity is insufficient or patients find it impractical. By systematically capturing the perspectives of both staff and patients, and by triangulating these accounts with attendance data, the Welsh team has produced the kind of implementation intelligence that health boards across the United Kingdom and beyond can learn from.

Despite its successes, the evaluation identified a significant gap that the programme and the wider health system must address: post-treatment support. Patients and the evaluation highlighted a need for improved rehabilitation after treatment to ensure that the healthy behaviours established during prehabilitation are sustained. This finding points to a structural weakness in many cancer pathways, where support intensifies before treatment and then tapers off precisely when patients are grappling with the physical aftermath of surgery or the fatigue of chemotherapy. Without a bridge from prehabilitation to rehabilitation, the gains made in the pre-treatment window risk erosion. The programme’s very name, Prehab2Rehab, signals an ambition to create that continuum, but the evaluation suggests that the rehabilitation side of the equation requires further development to match the pre-treatment phase.

The implications of this research extend well beyond Wales. Health systems internationally are grappling with how to embed prehabilitation into standard cancer care, driven by evidence that it can improve surgical outcomes and recovery. The Welsh experience demonstrates that such programmes can deliver positive patient experiences and genuine lifestyle change when delivered through a national health service, but it also provides a candid account of the challenges: unequal engagement across patient groups, the need for sustained support beyond the pre-treatment period, and the practical realities of delivering personalised, multimodal care at scale. As cancer survival rates improve and more people live with and beyond the disease, the question of how to prepare patients for treatment, and how to support them afterwards, will only grow in importance. This evaluation offers both a template and a warning: prehabilitation works best when it meets patients where they are, and its benefits endure only if the system is built to carry them forward.

The intervention at the heart of the Whole Health Options and Pain Education, or wHOPE, study is the Whole Health Team, an interdisciplinary unit composed of a medical provider, a complementary and integrative health provider, and a health coach. Together, these clinicians provide holistic, non-pharmacological pain care grounded in VA’s broader Whole Health approach, which begins with open-ended inquiry into what matters most to each patient and proceeds through collaborative Personal Health Planning. Over twelve months, patients attended five or more collocated visits with the team’s medical and integrative providers, supplemented by eight or more health coaching visits, while weekly team huddles supported case management and care planning. In a national randomized controlled trial of 764 veterans with moderate to severe chronic pain, the Whole Health Team outperformed both modified Cognitive Behavioral Therapy for Chronic Pain and usual care in reducing pain interference and increasing use of non-pharmacological pain services, with patients also reporting greater improvements in overall health status and treatment satisfaction.

Given that demonstrated effectiveness, the research team led by Natalie Purcell, Liliana C. Moore, William C. Becker, and Karen H. Seal turned to a critical follow-up question: can this model actually be scaled? Because the Whole Health Team approach is not simply multimodal but also team-based, interdisciplinary, and integrated, requiring collocated clinical visits, routine coaching, and weekly huddles, it is more complex and resource-intensive than many other pain interventions. To investigate, the researchers conducted semi-structured interviews with 43 clinicians and staff involved in implementing the intervention, including 14 health coaches, 6 primary care providers, 6 integrative-trained providers, 5 other clinical professionals, 8 local site investigators, and 4 study coordinators. Guided by the Practical Robust Implementation and Sustainability Model, a framework that maps contextual factors from planning through sustainment, the team used template-based rapid analysis to distill themes from interviews lasting 30 to 60 minutes each.

The first major theme concerned team composition and collaboration, and here the clinicians were emphatic. They praised the interdisciplinarity of the model and described working in a genuinely integrated fashion rather than in silos. One medical provider captured the spirit of the collaboration vividly, recalling that the team was working with patients together, talking together, interrupting each other, and asking questions rather than operating separately. Collocated patient visits served as a central venue for this active collaboration, but so did the weekly huddles between visits, where hearing one another’s perspectives helped the team generate multiple options when patients faced challenges. A complementary and integrative health clinician noted that a single lens might not be the best thing for the patient, and expressed appreciation for the ability to hear the same piece of information and encounter completely different perspectives on how to manage it. Clinicians also believed that visible collaboration increased veteran engagement, with one coach observing that simply knowing the team was working together on their behalf gave patients another layer of buy-in.

Consistency of team membership emerged as another essential ingredient. Clinicians stressed that building trust with patients requires time and continuity, and that the twelve-month structure of regular clinical and coaching visits cultivated increased trust, deeper rapport, and genuine continuity of care. Patients came to depend on a familiar team they got to know, which in turn facilitated active involvement in care planning. Yet sustaining that consistency proved difficult. Because clinicians were volunteers lending their time from other duties, they were sometimes pulled off the study to devote resources elsewhere, a problem amplified during the COVID-19 pandemic during which all study interventions were delivered virtually. Clinician turnover interrupted care relationships and left key roles vacant at times, burdening remaining team members and making it harder to practice with a Whole Health approach. Interviewees stressed that team stability must be prioritized if relationship-based care is to survive contact with real-world staffing pressures.

Adequate, formally allocated clinician effort was perhaps the most contested resource of all. The Whole Health Teams operated in an institutional environment focused on optimizing productivity, where bookable hours were measured closely and every clinic scheduling grid was scrutinized. Both clinicians and site investigators emphasized the importance of protected time for team work, including dedicated clinic hours, time for writing notes, and time for the weekly huddles they considered critical. All participating sites did secure protected time, but doing so required staunch advocacy amid competition for clinical resources, and maintaining it remained an ongoing challenge. One site investigator described it as probably the biggest obstacle the team had faced. Clinicians also valued formal orientation to the team, which covered roles, visit protocols, and documentation requirements, though some, including several medical providers, retained uncertainty about their prescribing role relative to patients’ primary care providers, underscoring the need for clearly delineated responsibilities in interdisciplinary teams.

The second major theme involved organizational infrastructure and integration, beginning with the need to fill gaps rather than duplicate existing services. Because some VA health systems already offer pain-management and wellness programs, clinicians and investigators argued that the more resource-intensive Whole Health Team model must demonstrate unique value to make a viable business case for sustainment. They found that value in delivering an integrated, consistent message to each patient. One medical provider lamented that the health system is so fractured that patients see different people who tell them different things, and described the team as an efficient and effective way to help patients with a coherent care plan, noting that veterans like to see that their clinicians are all on the same page. The model also improved the clinicians’ own work experience, fostering mutual support and confidence when caring for patients with complex needs. At the same time, interviewees identified shortcomings: coordination with primary care sometimes felt informal, relying on discretionary co-signature of notes that primary care providers did not always read, and referral pathways to wellness and complementary modalities were often poorly mapped, forcing coaches to act as conduits to information that higher-level staff knew less and less about.

The third theme centered on administration and documentation, an unglamorous but decisive factor. Implementing collocated visits and concurrent health coaching is administratively complicated, and each site benefited from a study-funded, full-time coordinator who scheduled meetings and patients, set up clinic grids, collected point-of-care measures, tracked visits, completed documentation, made reminder calls, and served as an information hub for the whole team. One coordinator cautioned bluntly that if the model were implemented elsewhere, the level of administrative support provided in the study simply would not be available in a clinical service. Clinicians also chafed against standardized clinical note templates designed for study data collection, which felt ill-suited to personalized whole-person care. One provider asked why they needed to do math during a visit and take time away from listening to a veteran’s story, while another complained that templates force a robotic style that annoys patients. The consensus favored simpler, more flexible documentation that could adapt to each visit’s focus.

Perhaps the most striking finding was the depth of clinicians’ belief in the Whole Health model despite every implementation hurdle. Interviewees described practicing in line with their own values, connecting with patients more authentically, and witnessing emotional exit visits in which patients felt deeply cared for and equipped with new resilience and tools. One provider offered a sentiment that captures the model’s philosophy: patients are people, more than just a list of diagnoses, and they are fun and complicated. These accounts align with broader evidence that Whole Health practice may reduce clinician stress and burnout, and with VA survey findings that clinicians engaged in Whole Health view their workplaces more favorably and are less likely to resign. Yet many participants doubted the system would retain and spread the teams, perceiving the model as resource-intensive in an environment that rewards volume and perceived efficiency over quality, experience, and outcomes. They saw the teams as an upstream investment with downstream benefits, but acknowledged that a comprehensive longer-term cost-effectiveness analysis may be needed, particularly as an alternative to interventional pain care.

The study’s lessons amount to a practical blueprint for any health system contemplating integrated, person-centered pain care. Success requires consistent team membership, sufficient protected clinical effort, well-defined roles, team-based training, routine huddles, and skilled administrative support that could be provided by a nurse care manager or medical support assistant in the absence of a study coordinator. It also demands organizational readiness: accessible complementary and integrative health modalities, wellness programs, and health coaching, along with clear referral pathways connecting pain teams to those resources. Deeper integration with primary care, through periodic in-services or coaches already embedded in primary care, could strengthen both patient care and sustainability. As VA continues its transformation into a Whole Health System of Care, and as other integrated systems such as Kaiser Permanente pursue similar holistic models, the wHOPE findings illuminate both the promise and the price of treating chronic pain as a whole-person problem, offering hard-won insight into a care model that the clinicians who delivered it clearly believe is worth sustaining.
