Anti-obesity medications (AOMs) are pharmacological agents designed to assist with weight loss through various mechanisms, including appetite suppression, increased satiety, and inhibition of fat absorption. Recent studies have investigated the effectiveness of several AOMs concerning weight loss and alcohol use disorders (AUDs).
The complex relationship between anti-obesity medications and alcohol consumption has attracted considerable academic interest, as emerging research indicates potential benefits for individuals with alcohol use disorder. In this critical review, the authors examine the existing literature, focusing on the relevance of current findings for those diagnosed with AUD. The authors also highlight the limitations of these key studies and emphasize the urgent need for further research to clarify the methodological and psychosocial complexities involved in using AOMs to address alcohol-related challenges.
Keywords: anti-obesity medications (AOMs), alcohol consumption; bias in studies on anti-obesity medications in alcohol use-abuse treatment; neglect of cultural and social factors in studies on anti-obesity medications in alcohol use-abuse treatment
Recent investigations into anti-obesity medications (AOMs), particularly glucagon-like peptide-1 receptor agonists (GLP-1 RAs) such as Liraglutide and Semaglutide, have garnered significant academic interest due to their dual effects on weight management and alcohol consumption behaviors.1–3 These pharmacological agents are recognized for their substantial role in weight loss and improving metabolic health. More recently, they have been examined for their potential impact on drinking patterns among obese individuals.1–4
However, there is no clear and definitive evidence that these findings translate to improved outcomes for individuals with Alcohol Use Disorder (AUD).5 A critical consideration is that the mechanisms by which these medications may influence drinking behaviors—particularly their direct effects on the brain's reward pathways—remain inadequately understood.6 Furthermore, the motivations for alcohol consumption, especially in the context of AUD, are deeply rooted in psychological, social, and environmental factors.7
Consequently, the observed reductions in alcohol intake may not accurately reflect the true efficacy of AOMs, as other factors may influence treatment success or failure.8
The positive perception surrounding the therapeutic benefits of anti-obesity medications (AOMs) can be partly attributed to the extensive publicity generated by the pharmaceutical industry—a strategy that has not been similarly employed for Medications for Alcohol Use Disorder (MAUD). Despite some positive data supporting MAUD, these medications have not received equivalent enthusiastic attention.9–16 The societal stigma associated with developing and marketing medications for treating drug-dependent patients poses a significant concern for pharmaceutical companies.9,16 They may be concerned that once a medication is approved for use in the treatment of drug addiction, the market for other indications will diminish or disappear. Patients, in general, are reluctant to take medications associated with drug addiction.9,10 Consequently, the pharmaceutical industry seems hesitant to develop compounds only specific to drug addiction if other medical uses for them could be marketed.9,16
The pharmaceutical industry exhibits notable differences in their investment and marketing strategies for AOMs compared to MAUD medications.9 In the first half of 2023, drug manufacturers allocated nearly $500 million to advertise obesity and diabetes medications, illustrating their capacity to influence societal perceptions concerning weight management.11,12
Obesity drugs have emerged as “disruptors” on a scale matched by few other pharmaceutical innovations. Their emergence, along with a shift in the way obesity and related illnesses are regarded and treated, has positioned this new class of drugs on a blockbuster path with no signs of abating.11–13
In light of this surging demand, Morgan Stanley Research has re-evaluated the global market for obesity drugs, now projecting it to reach $105 billion by 2030, up from an earlier forecast of $77 billion, and potentially as high as $144 billion. Sales of branded obesity drugs were $6 billion in 2023.13
Through strategic use of public figures and extensive marketing campaigns, pharmaceutical companies have successfully raised awareness and normalized the negative perceptions and social stigma associated with being overweight, thereby fostering a positive attitude towards weight loss interventions.9,11–16 Conversely, MAUD medications have experienced significantly less effective marketing, hindering their reach to potential patients and failing to address the stigma surrounding alcohol use disorders.12,16
Pharmaceutical marketing strategies emphasize the importance of weight loss for overall health improvement, thus positioning AOMs within the context of holistic wellness. This may inadvertently normalize the use of these medications among individuals struggling with addiction. Reports indicate that pharmaceutical companies utilize direct-to-consumer advertising, highlighting testimonials and alleged success stories of AOM users, thus shaping patient perceptions and potentially influencing their treatment choices.11,13,14
Without a doubt, the prominence of these marketing efforts raises ethical concerns about potentially weakening the focus on comprehensive addiction treatment approaches. While AOMs may offer some benefits, reliance on pharmacotherapy without a strong emphasis on behavioral and life-changing approaches could undermine the effectiveness of treatment programs for SUDs and AUDs and the pivotal clinical aspects of mental and physical well-being.17–19 Even if, on paper, emphasis on lifestyle changes may be identified and stressed, in reality, the massive marketing obscures them by emphasizing the properties and effects of these new medications as an absolutely effective and innovative approach. Therefore, a balanced treatment strategy that emphasizes both behavioral interventions and pharmacological support is vital, alongside ongoing scrutiny of the implications of pharmaceutical marketing on clinical practices.11,13–19
Thus, while AOMs offer an innovative avenue for addressing weight-related issues intertwined with alcohol use disorder, their promotion requires cautious handling. It is essential to ensure that ethical considerations are upheld and that patients receive comprehensive care tailored to their needs.17–19
A thorough examination is essential regarding how treatment options for substance use disorders (SUDs) and alcohol use disorder (AUD) are conceptualized, presented, and perceived. This is particularly important for historically marginalized and minority populations who often experience the most severe consequences of these disorders. These groups also face unfavorable social determinants of health, which serve as barriers to making lifestyle changes and accessing proper nutrition. Such challenges are critical in addressing obesity and comorbidity conditions associated with it.20–25
This article evaluates the evidence on the effectiveness of anti-obesity medications (AOMs) in reducing alcohol consumption among individuals with co-occurring obesity and problematic drinking or AUD. Drawing on the limited number of pivotal studies available from the specialized literature, it underlines the need for psychosocial and culturally based approaches, which may have more realistic chances for long-term positive outcomes.11–14,16–19
The primary objective is to maintain a realistic perspective on the therapeutic potential of AOMs to assist clinicians in making informed decisions about their use in clinical practice. Furthermore, the article emphasizes the importance of incorporating cultural and social factors into future investigations of AOM efficacy, highlighting the interplay between biological, psychosocial, and cultural factors in AUD treatment, especially within the context of weight-related concerns.26–32
Main methodological issues in current studies on the efficacy of anti-obesity medications for alcohol consumption
The comorbidity of problematic drinking and alcohol use disorder (AUD) with weight problems and obesity presents a complex challenge for individuals, clinicians, and researchers.33,34
This article reviews the effectiveness of anti-obesity medications (AOMs) in reducing alcohol consumption among people struggling with significant drinking issues, which are defined here as both problematic drinking and AUD, essentially referring to the same conditions.35,36
These conditions are characterized by an individual's inability to control their alcohol intake despite facing adverse consequences. They encompass a range of issues from mild to severe and can negatively influence various aspects of a person's life, including physical health, social relationships, and career prospects.35,36
Behaviors associated with AUD, such as binge drinking and heavy consumption, often worsen the situation. Furthermore, these behaviors are influenced by numerous psychological, physiological, and sociocultural factors, highlighting the need for a contextual approach to fully understand these interconnections.35–37
Many studies highlight the importance of these critical elements to enhance the relevance and applicability of treatment modalities in real-world settings. By examining the limited but significant specialized literature on the efficacy of anti-obesity medications (AOMs) in reducing alcohol consumption by those with serious drinking problems, the authors emphasize the necessity of a multifaceted understanding of the psychosocial and cultural complexities surrounding interventions for AUD and problematic drinking.20–30 The article's primary goal is to highlight the potential shortcomings of narrow pharmacologic-based approaches, which by themselves may not be able to address both the areas of AUDs and Obesity management.

Issues with generalization and sociocultural considerations in anti-obesity medication research
Understanding the impact of anti-obesity medications (AOMs) on alcohol cannot ignore the limitations identified in the reviewed studies. Potential biases in self-reported data; limited sampling; absence of a control group; lack of specific diagnostic, neglect of sociocultural aspects; unclear classifications for alcohol use disorder are relevant issues with impact on clinical decisions. In the treatment of AUDs, SUDs and obesity it is pivotal to adopt a comprehensive approach, taking into account individual patient histories, the sociocultural context and the nuanced effects of both medications and behavioral interventions.20–32 This careful consideration is critical to ensure that AOMs are prescribed in a way that addresses both weight management and alcohol consumption issues without overlooking the complexities of each patient’s histories and sociocultural makeups.
Regarding the studies included in the article, a summary of salient considerations include:
A significant factor that can underlie both mental health issues and substance abuse problems, often overlooked, is the trauma experienced within a sociocultural context. Trauma can lead to negative coping mechanisms, where individuals may turn to alcohol or drugs to alleviate their emotional burden. Research indicates that a history of trauma, particularly in childhood, is strongly associated with later substance abuse and mental health disorders. The adverse effects of trauma can manifest in various ways, including emotional dysregulation, increased impulsivity, and altered stress responses—all factors that contribute to the development of alcohol and substance use disorders.66
These phenomena reside within the psychosocial dimension of health, highlighting the importance of addressing the broader context in which individuals exist. Factors such as social support, socioeconomic status, and access to healthcare services are pivotal in shaping the experiences of those with comorbid conditions.67 Moreover, the interplay of these factors can perpetuate cycles of substance abuse and obesity, as individuals may find themselves in environments that hinder recovery and promote unhealthy coping strategies.68
Consequently, it is crucial to tackle the intricate network of interconnections to create effective interventions and support systems that align with the real-life experiences of those affected. As discussed, incorporating the psychosocial and cultural dimensions related to alcohol and substance use problems, as well as obesity, is vital for constructing successful interventions. Furthermore, highlighting the significance of mental health and the effects of psychological trauma will enhance both research findings and treatment effectiveness for individuals facing these intertwined challenges.
While anti-obesity medications (AOMs) offer an avenue for addressing obesity and potentially affecting alcohol consumption, they cannot independently and sufficiently encompass the psycho-socio-cultural underpinnings that contribute to these disorders. The intersection of AOMs and alcohol consumption necessitates a nuanced understanding of the sociocultural dimensions influencing behavioral health. A reliance on pharmacological interventions for managing weight and alcohol use often overshadows the intricate interplay of psychosocial and cultural factors critical to addressing these complex issues.18–32
Medical sociological literature provides insight into these dynamics. Ivan Illich, in his seminal work "Medical Nemesis," argues that over-reliance on medical solutions can obscure deeper sociocultural contexts, leading to a disempowerment of individuals and diverting attention away from personal responsibility and community-based support systems essential for holistic health outcomes.69,70 Similarly, Waitzkin emphasizes the importance of understanding healthcare delivery within the broader social context, noting that socioeconomic status, cultural norms, and personal histories profoundly influence medical interactions.71
In addition, Native psychologist Duran highlights the significance of culturally relevant frameworks in addressing behavioral health challenges, advocating for culturally attuned interventions to enhance efficacy and patient’s adherence.72,73 This perspective is echoed by Rudolf Virchow’s historical insights that health is inherently a social issue, urging recognition of the sociopolitical determinants of health and implicitly challenging the notion that pharmacological interventions alone can rectify health disparities related to weight and alcohol consumption.74,75
It is essential to adopt a holistic approach that goes beyond pharmacological solutions to pursue the complexities surrounding weight management and alcohol consumption. The current emphasis and developing reliance on AOMs do not fully consider the intricate web of psychological, social, and environmental factors involved.18–32
In addition, cultural attitudes toward alcohol and dietary practices differ greatly among communities, influencing individual interactions with both substances. Additionally, stigma can exacerbate challenges, discouraging individuals from seeking help or sticking to treatment plans.18–32
Moreover, varying metabolic responses among different ethnic and racial groups highlight the limitations of a one-size-fits-all pharmacological approach.50–53 Personalized treatment strategies that incorporate cultural sensitivity and psychosocial factors are necessary.18–32 As stated previously, clinical providers must carefully consider the long-term side effects of these medications.56–60
It is crucial to advocate for research methodologies that include diverse populations and culturally relevant factors.18–32,56–60 This effort could empower practitioners to implement more comprehensive treatment approaches. The suggestion that AOMs could help reduce alcohol consumption should be approached with caution, especially regarding alcohol use disorders (AUDs), where behavioral modifications and sociocultural support are often more effective than pharmacological interventions alone.18–32,56–60
Theoretical approaches, such as the Cultural Influences on Mental Health (CIMH) Model and the Socio-Cultural Model, emphasize the importance of culturally sensitive interventions, community support systems, and the broader social determinants of health. These models recognize the significant role that cultural and social contexts play in shaping health behaviors and outcomes, advocating for holistic and community-based interventions.76,77–83 Regrettably, even in the absence of clear evidence demonstrating the long-term effectiveness and superiority of narrow pharmacological approaches to behavioral health and substance abuse, these methods, along with similar comprehensive strategies, continue to be undervalued. This persistence is partly due to the significant influence of the pharmaceutical industry. As well documented, the industry shapes clinical guidelines and treatment practices, often prioritizing drug targets and biomedical narratives at the expense of behavioral and sociocultural interventions.84–87
Rudolf Virchow's insightful statement that "medicine is a social science, and politics is nothing else but medicine on a large scale" underscores the critical need to incorporate social and cultural contexts into medical practices to identify the root causes of health issues. This perspective is particularly relevant in the management of complex health conditions such as obesity and alcohol consumption, where sociocultural factors play a significant role.88 For instance, a holistic approach to managing obesity would consider not only the individual's diet and physical activity but also their social environment, cultural norms, and economic conditions. Similarly, addressing alcohol consumption would involve understanding the social contexts in which drinking occurs, the cultural attitudes towards alcohol, and the availability of social support systems. In this context, the relationship between alcohol consumption, dietary intake, and body weight underscores the complex interplay of individual, sociocultural, and environmental factors.89
Virchow's statement encapsulates the fundamental idea for management of health conditions like obesity and alcohol consumption, it is crucial to integrate sociocultural dimensions into medical practices. This holistic approach not only addresses the symptoms but also tackles the root causes, leading to more sustainable health outcomes.18–32,56–60 Given this situation, we must keep in mind the broader potential implications of relying heavily on pharmacological approaches. Henceforth, it is crucial to integrate pharmacological treatments with holistic, culturally sensitive interventions to achieve more comprehensive and sustainable health outcomes. Consequently, future research should incorporate diverse perspectives to develop evidence-based strategies for addressing weight loss and alcohol use disorders that resonate with the lived experiences and sociocultural realities of individuals.18–32,56–60
