Clinicians continue to argue that solely focusing on weight in discussions with patients with obesity can be harmful. But with highly effective agents like semaglutide and tirzepatide, more discussions are being had about obesity, in and out of the doctor’s office.
In this time of new therapeutic options, it’s critical to be thoughtful in how we broach the topic of weight management and obesity treatments with our patients.
With a stigmatized topic like obesity, it’s not surprising that there is contention surrounding the issue. Weight stigma and discrimination persist worldwide, even though there is ample scientific evidence that weight regulation is strongly determined by uncontrollable factors.
However, the debate to discuss weight or not doesn’t need to be polarized. There is a common denominator: Help patients live healthy, long lives. Let’s review the principles of the various approaches to care.
Chronic Disease–Centric Paradigm
Historically, physicians have addressed and managed chronic diseases, such as type 2 diabetes, hypertension, and dyslipidemia. Even though obesity is a known risk factor for these conditions and can cause many other diseases through low-grade chronic inflammation issues and organ dysfunction, weight management treatment was an afterthought or never entertained.
During my training, I often wondered why we focused on prescribing medications for multiple chronic diseases instead of addressing obesity directly, which could potentially improve all these conditions.
There are numerous reasons why this paradigm was viewed as the “standard of care” for so many decades. First, it provided a framework for managing an ever-growing list of chronic diseases. And even though the American Medical Association declared obesity a disease in 2013, this was not widely accepted in the healthcare community.
Healthcare systems and the US reimbursement model have been aligned with a chronic disease treatment paradigm. At the same time, healthcare professionals, like others in society, harbor prejudices. These have presented significant barriers to providing weight management care.
Additionally, medical education was, and remains, inadequate in training physicians how to prevent and treat obesity.
Weight-Centric Paradigm
The literature defines a weight-centric approach to care as one that places significant emphasis on body weight as a primary indicator of health — a perspective that may view lower body weight as inherently healthier. This approach includes comprehensive treatment of obesity that factors in lifestyle, pharmacotherapy, procedures, and surgery. A weight-centric approach has been described as having six tenets, examples of which are “weight is mostly volitional and within the control of the individual,” and “excess body weight causes disease and premature death.” This approach heavily relies on body mass index (BMI) as an indicator of a patients’ current and future health status.
We know that using BMI as a measure of health has inherent limitations. Recent recommendations suggest that it be used alongside other measurements and assessments, such as waist circumference and waist-to-hip ratio. One major concern with the paradigm, however, is that it can perpetuate weight stigmatization through an overemphasis on weight vs global health. The definition doesn’t acknowledge the wealth of data demonstrating the associated risk increased that central adiposity poses for increased morbidity and mortality. The answer needs to be more nuanced.
Instead of watering down a “weight-centric approach” to be equated with “weight equals health,” I propose it could mean addressing obesity upstream (ie, an adipose-centric approach) to prevent associated morbidity and mortality downstream.
Also, measuring a patient’s weight in the clinic would be an impartial act, obtaining a routine data point, like measuring a person’s blood pressure. Just as it is necessary to obtain a patient’s blood pressure data to treat hypertension, it is necessary to obtain adiposity health-related data (eg, weight, waist circumference, neck circumference, waist-to-hip ratio, weight history, physical exam, lab tests) to make informed clinical decisions and safeguard delivery of evidence-based care.
A weight-centric approach is a positive shift from focusing solely on chronic diseases because it allows us to address obesity and explore treatment options. However, challenges remain with this approach in ensuring that weight management discussions are handled holistically, without bias, and with sensitivity.
