RESUMEN
Obesity is a complex chronic disease with increasing prevalence across the globe. Medical nutrition therapy (MNT) is an important component of obesity treatment, and low-calorie diets (LCDs) and very-low-calorie diets (VLCDs) are part of the MNT toolbox. This narrative review focuses on the latest evidence and clinical guidelines regarding the use and impact of meal replacements (MRs) as part of LCDs/VLCDs for the treatment of obesity and some associated complications. MRs can be used in conjunction with food as partial diet replacement (PDR) or can be used exclusively to serve as the sole source of dietary energy (total diet replacement [TDR]). Use of MR may be associated with better control of cravings and hunger typically observed during reduced calorie intake through effects of ketosis or stimuli narrowing, although the exact mechanisms for these effects remain unclear. Several clinical guidelines have endorsed the use of MRs as a part of MNT for obesity, primarily based on evidence that shows an average weight reduction of ~10 kg or more with TDR over at least 12 months in large, randomized controlled trials. When compared to usual care controls, these effects are 6-8 kg greater, and when compared to food-based diets, the effects are nearly twice the effect of a food-based diet. MR-based diets have been found to be safe and associated with improvements in quality of life. These diets are also effective for improving key cardiometabolic health outcomes, including dysglycaemia, blood pressure, lipids, and metabolic associated fatty liver. The effectiveness, safety, and associated health improvement makes MRs use a valuable strategy for several higher risk clinical scenarios where weight reduction is indicated.
RESUMEN
Background: An international panel of obesity medicine experts from multiple professional organizations examined patterns of obesity care and current obesity treatment guidelines to identify areas requiring updating in response to emerging science and clinical evidence. Aims: The panel focused on multiple medical health and societal issues influencing effective treatment of obesity and identified several unmet needs in the definition, assessment, and care of obesity. Methods: The panel was held in Leesburg, Virginia in September 2019. Results: The panelists recommended addressing these unmet needs in obesity medicine through research, education, evaluation of delivery and payment of care, and updating clinical practice guidelines (CPG) to better reflect obesity's pathophysiological basis and heterogeneity, as well as the disease's health, sociocultural, and economic complications; effects on quality of life; need for standards for quantitative comparison of treatment benefits, risks, and costs; and the need to more effectively integrate obesity treatment guidelines into routine clinical practice and to facilitate more direct clinician participation to improve public understanding of obesity as a disease with a pathophysiological basis. The panel also recommended that professional organizations working to improve the care of people with obesity collaborate via a working group to develop an updated, patient-focused, comprehensive CPG establishing standards of care, addressing identified needs, and providing for routine, periodic review and updating. Conclusions: Unmet needs in the definition, assessment and treatment of obesity were identified and a blueprint to address these needs developed via a clinical practice guideline that can be utilized worldwide to respond to the increasing prevalence of obesity.
RESUMEN
The improved efficacy and generally favorable safety profile of recently approved and emerging antiobesity medications (AOMs), which result in an average weight reduction of ≥15%, represent significant advancement in the treatment of obesity. This narrative review aims to provide practical evidence-based recommendations for nutritional assessment, management, and monitoring of patients treated with AOMs. Prior to treatment, clinicians can identify preexisting nutritional risk factors and counsel their patients on recommended intakes of protein, dietary fiber, micronutrients, and fluids. During treatment with AOMs, ongoing monitoring can facilitate early recognition and management of gastrointestinal symptoms or inadequate nutrient or fluid intake. Attention should also be paid to other factors that can impact response to treatment and quality of life, such as physical activity and social and emotional health. In the context of treatment with AOMs, clinicians can play an active role in supporting their patients with obesity to improve their health and well-being and promote optimal nutritional and medical outcomes.
RESUMEN
OBJECTIVE: Limited recent evidence exists regarding weight-reduction preferences among people with obesity in the United States (US). We assessed preferred magnitudes of weight reduction among adults with obesity and how these preferences differ by participant characteristics. METHODS: The Perceptions, Barriers, and Opportunities for Anti-obesity Medications in Obesity Care: A Survey of Patients, Providers and Employers was a cross-sectional study assessing perceptions of obesity and anti-obesity medications among people with obesity, healthcare providers, and employers in the US. Adults with obesity and overweight with obesity-related complications self-reported current weight and weight they associated with 5 preferences ("dream," "goal," "happy," "acceptable," and "disappointed.") Preferred percent weight reductions for each preference were calculated. Multivariable regression analyses were performed identifying associations between weight-reduction preferences and participant characteristics. RESULTS: The study included 1007 participants (women: 63.6%; White: 41.0%; Black or African American: 28.9%; Asian: 6.5%; Hispanic: 15.3%; and median body mass index (BMI): 34.2 kg/m2). Median preferred percent weight reductions were dream = 23.5%; goal = 16.7%; happy = 14.6%; acceptable = 10.3%; and disappointed = 4.8%. Women reported higher preferred weight reductions than men. Preferred weight reductions among Black/African American participants were lower than White participants. Regression analyses indicated significant associations, with higher preferred magnitudes of weight reduction within females, higher weight self-stigma, and BMI class in Hispanic participants compared to White. CONCLUSION: In this large, real-world study, preferred magnitudes of weight reduction exceeded outcomes typically achieved with established nonsurgical obesity treatments but may be attained with bariatric procedures and newer and emerging anti-obesity medications. Respecting patients' preferences for treatment goals with obesity management could help support shared decision-making. Evaluating for an individual's contributors to weight preferences, such as weight self-stigma, can further benefit holistic obesity care.
RESUMEN
OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of semaglutide 2.4 mg, a glucagon-like peptide-1 receptor agonist, by race and ethnicity, across three phase 3 trials. METHODS: The Semaglutide Treatment Effect in People with Obesity (STEP) clinical trials evaluated the efficacy and safety of once-weekly subcutaneous semaglutide 2.4 mg. Here, STEP 1 and 3 data were pooled for analysis; STEP 2 data were examined separately. All analyses were conducted using data from racial and ethnic subgroups. The primary outcome was the estimated treatment difference in percent body weight change for semaglutide 2.4 mg versus placebo. RESULTS: Participants reported race as White (STEP 1 and 3, 75.3%; STEP 2, 59.4%), Black (8.8%; 8.9%), Asian (10.6%; 27.3%), or other racial group (5.3%; 4.4%); and ethnicity as Hispanic or Latino (13.9%; 11.9%) or not Hispanic or Latino (83.9%; 88.1%). There were no significant interactions between treatment effect and race (STEP 1 and 3: p ≥ 0.07; STEP 2: p ≥ 0.15) or ethnicity (p ≥ 0.40; p ≥ 0.85). The safety of semaglutide 2.4 mg was consistent across subgroups. CONCLUSIONS: The treatment effect of semaglutide was statistically significant versus placebo and clinically relevant across all racial and ethnic subgroups in STEP 1 and 3 and STEP 2. All subgroups across both samples demonstrated good tolerability.

PURPOSE OF REVIEW: This review provides an overview of the history, mechanism of action, and expected treatment effects of the anti-obesity medication (AOM), phentermine. It also includes a summary of recent research and practical guidance for prescribing clinicians. RECENT FINDINGS: Recent research on phentermine is sparse and consists primarily of observational studies with methodologic limitations. These studies suggest that phentermine use is associated with clinically significant weight loss in adults and that the medication is generally well tolerated. Large-scale observational studies evaluating phentermine's safety have not identified an increased risk of cardiovascular events or elevations in blood pressure. There is no data to support the notion that phentermine is addictive. Although it remains the most commonly prescribed AOM in the USA, phentermine has little rigorous research to support its efficacy and safety in long-term treatment, which creates a dilemma with guideline-recommended chronic use of AOMs. While we await forthcoming conclusive data on this front, clinicians may consider using phentermine long-term in selected patients, if such prescribing is consistent with local regulatory statutes.

Historically, obesity was viewed as a lifestyle disease, with an associated lifestyle solution, and approaches that embody the "eat less, move more" idea have dominated obesity treatment recommendations for over half a century. Meanwhile, the prevalence and severity of obesity continue to increase globally. Enter the so-called "game changers": glucagon-like peptide-1 receptor agonists. In the media frenzy around these and other new antiobesity medications in the pipeline, lifestyle-based treatment researchers and practitioners may find themselves wondering whether behavioral approaches to obesity will become obsolete in this new therapeutic era. In this Perspective, the authors contend that medical approaches impact physiologic pathways to support the success of behavioral approaches. Similarly, behavioral approaches can improve weight loss-adjacent outcomes that are not addressed by medication. Thus, the two approaches are complementary and must coexist if we are to make a significant, population-level impact on the obesity epidemic.

AIM: The effects of weight loss with a partial or total meal replacement programme (MRP) on atherosclerotic cardiovascular disease (ASCVD) risk factors are not fully understood, in particular in people at higher CV risk. In the 52-week randomized controlled OPTIWIN study in men and women with obesity, meal replacement programme (total for first 26 weeks, partial for the ensuing 26 weeks) with OPTIFAST (OP) resulted in significantly greater weight loss compared with a low-calorie food-based (FB) dietary plan, both as part of a comprehensive lifestyle intervention [OP (n = 135)/FB (n = 138) week 26: -12.4%/-6.0%, p < .001; week 52: -10.5%/-5.5%, p < .001]. Here, we examined effects on ASCVD risk factors and 10-year ASCVD risk. MATERIALS AND METHODS: Participants with body mass index 30-55 kg/m2 and age 18-70 years, and not on anti-obesity medications, were recruited. The effects on systolic and diastolic blood pressure (SBP, DBP), lipid parameters and 10-year ASCVD risk were analysed as changes over time using linear mixed models. Subgroup analyses were conducted for changes in SBP, DBP and ASCVD risk by categories of age (<40, 40-59, ≥60 years), baseline SBP (≥130 mmHg) and sex. RESULTS: Baseline characteristics were well balanced (OP/FB females 86%/79%, mean age 47/47 years, body mass index 38.4/39.2 kg/m2 , 10-year ASCVD risk <5% 87%/74%, dysglycaemia 52%/50%). At week 26, SBP/DBP were significantly reduced with OP versus FB, and a greater proportion achieved BP ≤130/80 mmHg [odds ratio 2.11 (95% confidence interval 1.10, 4.03), p = .024]. All lipid parameters as well as 10-year ASCVD risk were significantly improved with OP versus FB. A similar, but slightly attenuated pattern was observed at 52 weeks. Across subgroups, greater reductions for SBP, DBP and ASCVD risk were generally seen with OP versus FB with quantitatively higher baseline SBP and age, and in men. CONCLUSIONS: In people with obesity at low ASCVD risk, OP significantly reduced cardiovascular risk factors and 10-year predicted risk for ASCVD.

The effects of tirzepatide, a glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, on weight reduction after successful intensive lifestyle intervention are unknown. This double-blind, placebo-controlled trial randomized (1:1) adults with body mass index ≥30 or ≥27 kg/m2 and at least one obesity-related complication (excluding diabetes), who achieved ≥5.0% weight reduction after a 12-week intensive lifestyle intervention, to tirzepatide maximum tolerated dose (10 or 15 mg) or placebo once weekly for 72 weeks (n = 579). The treatment regimen estimand assessed effects regardless of treatment adherence in the intention-to-treat population. The coprimary endpoint of additional mean per cent weight change from randomization to week 72 was met with changes of -18.4% (standard error (s.e.) 0.7) with tirzepatide and 2.5% (s.e. 1.0) with placebo (estimated treatment difference -20.8 percentage points (95% confidence interval (CI) -23.2%, -18.5%; P < 0.001). The coprimary endpoint of the percentage of participants achieving additional weight reduction ≥5% was met with 87.5% (s.e. 2.2) with tirzepatide and 16.5% (s.e. 3.0) with placebo achieving this threshold (odds ratio 34.6%; 95% CI 19.2%, 62.6%; P < 0.001). The most common adverse events with tirzepatide were gastrointestinal, with most being mild to moderate in severity. Tirzepatide provided substantial additional reduction in body weight in participants who had achieved ≥5.0% weight reduction with intensive lifestyle intervention.

Background: Despite recognized improvements in obesity-related comorbidities, mounting evidence implicates surgical weight loss in the onset of skeletal fragility. Sleeve gastrectomy (SG) is the most commonly performed bariatric procedure and is associated with 3-7% axial bone loss in the year following surgery. Bisphosphonates are FDA-approved medications for the prevention and treatment of age-related bone loss and may represent a strategy to reduce bone loss following SG surgery. Methods: The Strategies to Reduce the Onset of Sleeve Gastrectomy Associated Bone Loss (STRONG BONES) trial (NCT04922333) is designed to definitively test whether monthly administration of the bisphosphonate, risedronate, for six months can effectively counter SG-associated bone loss. Approximately 120 middle-aged and older (≥40 years) SG patients will be randomized to six months of risedronate or placebo treatment, with skeletal outcomes assessed at baseline, six, and 12-months post-surgery. The primary outcome of the trial is 12-month change in total hip areal bone mineral density (aBMD), measured by dual energy x-ray absorptiometry (DXA). This will be complemented by DXA-acquired aBMD assessment at other skeletal sites and quantitative computed tomography (QCT) derived changes in bone quality. Change in muscle mass and function will also be assessed, as well as biomarkers of bone health, turnover, and crosstalk, providing mechanistic insight into intervention-related changes to the bone-muscle unit. Discussion: Results from the STRONG BONES trial have the potential to influence current clinical practice by determining the ability of bisphosphonate use to mitigate bone loss and concomitant fracture risk in middle-aged and older SG patients.
RESUMEN
Introduction: In June 2013, the American Medical Association (AMA), one of the most influential healthcare organizations in the United States, voted to recognize obesity as a disease. Many who supported this change believed that recognition by AMA of obesity as a disease would serve as a tipping point that would increase access to care, accelerate training and research on the prevention and treatment of obesity, and reduce weight stigma. On the 10-year anniversary of this vote, this perspective piece outlines key advances made, as well as unrealized potential, in improving the obesity public health landscape since the AMA's classification of obesity as a disease. Methods: We draw on the empirical literature, as well as our experiences as clinical psychologists, a physician, and public health researchers specializing in obesity, to provide an overview of major advances and continued challenges in improving access to obesity treatment, accelerating prevention and training, and reducing weight stigma. We also outline important next steps to advance these goals. Results: While several notable advancements have occurred, significant work remains to create equitable access to evidence-based treatments, bring research and training on obesity on par with its prevalence, and reduce the pervasiveness and harm of weight stigma. Conclusion: The past decade has witnessed some advances with respect to access to care and attention, yet there is unrealized potential that awaits attention. Truly conceptualizing and treating obesity as a chronic disease requires a major paradigm shift.
RESUMEN
AIMS: We examined the contribution of changes in diet quality, physical activity and weight loss to improvements in insulin resistance (HOMA-IR index) and fasting glucose concentrations in a long-term behavioural trial. Furthermore, we compared the effects of lifestyle changes on glycaemic markers for individuals with and without prediabetes. MATERIALS AND METHODS: The PREMIER trial was an 18-month parallel randomized trial of the impact of behavioural lifestyle interventions implementing lifestyle recommendations (dietary changes, physical activity, moderate weight loss) in adults with prehypertension or stage 1 hypertension. We analysed data on 685 men and women without diabetes. Data on body weight, fitness (treadmill test), dietary intake (24-h recalls) and glycaemic outcomes were collected at baseline and at 6 and 18 months. We used general linear models to assess the association between the exposure variables and glycaemic markers. RESULTS: The mean (SD) age was 49.9 (8.8) years, the mean (SD) body mass index was 32.9 (5.7) kg/m2 , and 35% had prediabetes at baseline. Weight loss and improvements in fitness and diet quality were each significantly associated with lower HOMA-IR and fasting glucose concentrations at 6 and 18 months. Mediation analysis indicated that the effects of fitness and diet quality were partly mediated by weight loss, but significant direct effects of diet and fitness (independent of weight changes) were also observed. Furthermore, insulin sensitivity and fasting glucose improved significantly in participants with and without prediabetes. CONCLUSIONS: Our findings indicate that behavioural lifestyle interventions can substantially improve glucose metabolism in persons with and without prediabetes and that the effects of diet quality and physical activity are partly independent of weight loss.

Background: Despite robust weight loss and cardiometabolic benefit, lean mass loss following sleeve gastrectomy (SG) confers health risk. Bisphosphonates are a potential therapeutic agent for lean mass maintenance. Thus, our objective was to explore the effect of six months of risedronate (vs placebo) on change in dual energy x-ray absorptiometry (DXA) and computed tomography (CT) derived lean mass metrics in the year following SG. Methods: 24 SG patients were randomized to six months of 150 mg oral risedronate or placebo capsules (NCT03411902). Body composition was assessed at baseline and six months with optional 12-month follow-up using whole-body DXA and CT at the lumbar spine and mid-thigh. Group treatment effects and 95% CIs were generated from a mixed model using contrast statements at six and 12 months, adjusted for baseline values. Results: Of 24 participants enrolled [55.7±6.7 years (mean±SD), 79% Caucasian, 83% women, body mass index (BMI) 44.7±6.3kg/m2], 21 returned for six-month testing, and 14 returned for 12-month testing. Six-month weight loss was -16.3 kg (-20.0, -12.5) and -20.9 kg (-23.7, -18.1) in the risedronate and placebo groups, respectively (p=.057). Primary analysis at six-months revealed a non-significant sparing of appendicular lean mass in the risedronate group compared to placebo [-1.2 kg (-2.3, -0.1) vs -2.1 kg (-3.0, -1.2)]; p=.20. By 12-months, the risedronate group displayed no change in appendicular lean mass from baseline [-0.5 kg (-1.5, 0.6)]; however, the placebo group experienced significantly augmented loss [-2.9 kg (-3.6, -2.1)]. Conclusion: Pilot data indicate risedronate treatment may mitigate appendicular lean mass loss following SG. Further study is warranted.
RESUMEN
INTRODUCTION: The aim of the study was to compare eligible individuals who were or were not treated with bariatric surgery and describe disease burden, treatment, and healthcare costs over 3 years in individuals who were not. METHODS: Adults with obesity class II and comorbidities, or obesity class III, were identified in IQVIA Ambulatory EMR - US and PharMetrics® Plus administrative claims databases (January 1, 2007-December 31, 2017). Outcomes included demographics, BMI, comorbidities, and per patient per year (PPPY) healthcare costs. RESULTS: Of 127,536 eligible individuals, 3,962 (3.1%) underwent surgery. The surgery group was younger, a greater proportion were women, and mean BMI and rates of some comorbidities (obstructive sleep apnea, gastroesophageal reflux disease, and depression) were higher than in the nonsurgery group. Mean healthcare costs PPPY in the baseline year were USD 13,981 in the surgery group and USD 12,024 in the nonsurgery group. In the nonsurgery group, incident comorbidities increased during follow-up. Mean total costs increased by 20.5% from baseline to year 3, mostly driven by an increase in pharmacy costs; however, fewer than 2% of these individuals initiated antiobesity medications. CONCLUSIONS: Individuals who did not undergo bariatric surgery showed a progressive worsening of health and increasing healthcare costs, indicating a large unmet need for access to clinically indicated obesity treatment.

Obesity is increasing at an alarming rate. The effectiveness of currently available strategies for the treatment of obesity (including pharmacologic, surgical, and behavioral interventions) is limited. Understanding the neurobiology of appetite and the important drivers of energy intake (EI) can lead to the development of more effective strategies for the prevention and treatment of obesity. Appetite regulation is complex and is influenced by genetic, social, and environmental factors. It is intricately regulated by a complex interplay of endocrine, gastrointestinal, and neural systems. Hormonal and neural signals generated in response to the energy state of the organism and the quality of food eaten are communicated by paracrine, endocrine, and gastrointestinal signals to the nervous system. The central nervous system integrates homeostatic and hedonic signals to regulate appetite. Although there has been an enormous amount of research over many decades regarding the regulation of EI and body weight, research is only now yielding potentially effective treatment strategies for obesity. The purpose of this article is to summarize the key findings presented in June 2022 at the 23rd annual Harvard Nutrition Obesity Symposium entitled "The Neurobiology of Eating Behavior in Obesity: Mechanisms and Therapeutic Targets." Findings presented at the symposium, sponsored by NIH P30 Nutrition Obesity Research Center at Harvard, enhance our current understanding of appetite biology, including innovative techniques used to assess and systematically manipulate critical hedonic processes, which will shape future research and the development of therapeutics for obesity prevention and treatment.

Research shows that a diverse faculty improves academic, clinical, and research outcomes in higher education. Despite that, persons in minority groups, usually categorized by race or ethnicity, are underrepresented in academia (URiA). The Nutrition Obesity Research Centers (NORCs), supported by the NIDDK, hosted workshops on five separate days in September and October 2020. NORCs convened these workshops to identify barriers and facilitators for diversity, equity, and inclusion (DEI) and provide specific recommendations to improve DEI within obesity and nutrition for individuals from URiA groups. Recognized experts on DEI presented each day, after which the NORCs conducted breakout sessions with key stakeholders who engage in nutrition and obesity research. The breakout session groups included early-career investigators, professional societies, and academic leadership. The consensus from the breakout sessions was that glaring inequities affect URiA in nutrition and obesity, particularly related to recruitment, retention, and advancement. Recommendations from the breakout sessions to improve DEI across the academe focused on six themes: (1) recruitment, (2) retention, (3) advancement, (4) intersectionality of multiple challenges (e.g., being Black and a woman), (5) funding agencies, and (6) implementation of strategies to address problems related to DEI.

INTRODUCTION: Management of patients with BMI≥50 kg/m2 is challenging. In previous work, pre and postoperative pharmacotherapy with phentermine/topiramate plus laparoscopic sleeve gastrectomy (PT + SG) promoted greater weight loss than sleeve gastrectomy (SG) alone at 24 mo postoperatively. This current secondary analysis studied the impact of PT + SG on blood pressure (BP), heart rate, and antihypertensive usage. METHODS: Patients with BMI≥50 kg/m2 planning to have SG (n = 13) were recruited from 2014 to 2016, at an academic medical center in Winston-Salem, North Carolina, for this open-label trial. Participants took phentermine/topiramate (PT; 7.5/46-15/92 mg/d) for ≥3 mo preoperatively and 24 mo postoperatively. The control group (n = 40) underwent SG during the same time frame. We used mixed models for BP and heart rate to compare PT + SG versus SG alone over time, adjusted for age, sex, and initial BP. RESULTS: By 24 mo postoperatively the model adjusted changes in systolic blood pressure/diastolic blood pressure (SBP/DBP) (mm Hg) were -24.44 (-34.46,-14.43)/-28.60 (-40.74,-16.46) in the PT + SG group versus -11.81 (-17.58,-6.05)/-13.89 (-21.32,-6.46) in the control group (SBP P = 0.02; DBP P = 0.03). At baseline 8 (61.5%) participants in the PT + SG arm and 22 (55.0%) in the control group used antihypertensives. Excluding patients lost to follow-up (n = 3), by 24 mo postoperatively, none of the PT + SG participants were on antihypertensives compared to 14 (41.2%) in the control group (P = 0.01). CONCLUSIONS: Patients with BMI≥50 kg/m2 treated with PT + SG had greater improvement in BP with no use of antihypertensive medication at 24 mo postoperatively versus SG alone, where 41% continued medication use. Larger trials are required to evaluate this.
