Objective: SURMOUNT-MAINTAIN aims to evaluate the efficacy and safety of reducing the tirzepatide dose and/or continuing the maximum tolerated dose (MTD) versus placebo in maintaining body weight (BW) reduction achieved with tirzepatide MTD.

Methods: This Phase 3b, multicenter, randomized, parallel-arm, double-blinded, placebo-controlled, 52-week clinical trial is in progress comparing treatment with once weekly tirzepatide (5 mg and/or MTD of 15 mg or 10 mg) versus placebo in achieving BW reduction maintenance from the initial 60-week open-label weight-loss period on tirzepatide MTD, in adults with obesity (BMI ≥ 30 kg/m or ≥ 27 kg/m with ≥ 1 obesity-related comorbidity, excluding type 2 diabetes). The primary endpoint is percent maintenance of BW reduction achieved during the weight-loss period at Week 112 among those who reached a BW plateau (i.

Introduction: To co-create comprehensive targets for obesity management, we need to understand the genesis and current use of percent weight loss targets in research. The goals of our scoping review are to (1) synthesize the literature on percent weight loss targets for adults with obesity and (2) discuss the percent weight loss targets in context with their health benefits.

Methods: We searched Cochrane, MEDLINE, and EMBASE for English language, pharmaceutical, and/or behavioral intervention studies in adults with obesity where the explicit aim of the study was weight reduction defined as a percent of body weight.

Background: Tirzepatide and semaglutide are highly effective medications for obesity management. The efficacy and safety of tirzepatide as compared with semaglutide in adults with obesity but without type 2 diabetes is unknown.

Methods: In this phase 3b, open-label, controlled trial, adult participants with obesity but without type 2 diabetes were randomly assigned in a 1:1 ratio to receive the maximum tolerated dose of tirzepatide (10 mg or 15 mg) or the maximum tolerated dose of semaglutide (1.

The rate of weight reduction during obesity treatment declines over time and eventually reaches a weight plateau. We investigated factors associated with time to weight plateau (TTWP) in tirzepatide-treated participants with obesity or overweight in a post-hoc analysis of SURMOUNT-1 and SURMOUNT-4 trials. Participants adherent to tirzepatide treatment and achieving ≥5% weight loss by primary endpoint (week 72 SURMOUNT-1; week 88 SURMOUNT-4) were included.

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.

Objective: To determine whether semaglutide slows progression of glycemia in people with cardiovascular disease and overweight or obesity but without diabetes.

Research Design And Methods: In a multicenter, double-blind trial, participants aged ≥45 years, with BMI ≥27 kg/m2, and with preexisting cardiovascular disease but without diabetes (HbA1c <6.5%) were randomized to receive subcutaneous semaglutide (2.

In the SELECT cardiovascular outcomes trial, semaglutide showed a 20% reduction in major adverse cardiovascular events in 17,604 adults with preexisting cardiovascular disease, overweight or obesity, without diabetes. Here in this prespecified analysis, we examined effects of semaglutide on weight and anthropometric outcomes, safety and tolerability by baseline body mass index (BMI). In patients treated with semaglutide, weight loss continued over 65 weeks and was sustained for up to 4 years.

Importance: The effect of continued treatment with tirzepatide on maintaining initial weight reduction is unknown.

Objective: To assess the effect of tirzepatide, with diet and physical activity, on the maintenance of weight reduction.

Design, Setting, And Participants: This phase 3, randomized withdrawal clinical trial conducted at 70 sites in 4 countries with a 36-week, open-label tirzepatide lead-in period followed by a 52-week, double-blind, placebo-controlled period included adults with a body mass index greater than or equal to 30 or greater than or equal to 27 and a weight-related complication, excluding diabetes.

Background: Certification of obesity medicine for physicians in the United States occurs mainly via the American Board of Obesity Medicine (ABOM). Obesity medicine is not recognized as a subspecialty by the American Board of Medical Specialties (ABMS) or the American Osteopathic Association (AOA). This review examines the value of specialization, status of current ABOM Diplomates, governing bodies involved in ABMS/AOA Board Certification, and the advantages and disadvantages of an ABMS/AOA recognized obesity medicine subspecialty.

Aims: To determine the relationship between exposure and weight-loss trajectories for the glucagon-like peptide-1 analogue semaglutide for weight management.

Materials And Methods: Data from one 52-week, phase 2, dose-ranging trial (once-daily subcutaneous semaglutide 0.05-0.

Background: Despite the increasing prevalence of obesity, the use of pharmacotherapy treatment remains low. Telehealth platforms have the potential to facilitate access to pharmacotherapy interventions, but little is known about telehealth patients.

Objective: This study describes a large patient population taking Plenity, an oral superabsorbent hydrogel (OSH) used in the treatment of excess weight or obesity (BMI 25-40 kg/m).

Obesity is a chronic disease with increasing prevalence. It affects quality of life and renders those affected at increased risk of mortality. For people living with obesity, weight loss is one of the most important strategies to improve health outcomes and prevent or reverse obesity-related complications.

Purpose Of The Study: Obesity is a major risk factor for development and worsening of osteoarthritis (OA). Managing obesity with effective weight loss strategies can improve patients' OA symptoms, functionality, and quality of life. However, little is known about the clinical journey of patients with both OA and obesity.

Objective: This study aimed to explore the relationship between an obesity diagnosis and weight loss as a percentage of total body weight loss over 9 to 15 months, using electronic health record data.

Methods: An observational study of 688,878 adult patients at 15 health systems with BMI ≥ 30 kg/m examined the relationship between weight loss and documentation of obesity diagnosis. Multivariable logistic regression models were created using a stepwise backwards elimination procedure to identify potential predictors of weight loss.

Objective: Obesity Medicine Education Collaborative (OMEC) was formed to develop obesity-focused competencies and benchmarks that can be used by undergraduate and graduate medical education program directors. This article describes the developmental process used to create the competencies.

Methods: Fifteen professional organizations with an interest in obesity collaborated to form OMEC.

Although improvement of physical appearance is a primary motivating factor for patients, the fundamental purpose of weight loss is to improve health. Patients should be managed in the context of a chronic disease, taking a systematic approach to treatment. Lifestyle modification is the cornerstone of weight management.

Determining what treatment options the patient's insurance will cover and considering the patient's out-of-pocket costs are important actions to be taken while collaborating with the patient and other team members and during the development and implementation of the treatment plan. Reimbursement is available to PCPs for some obesity-related services.

Lifestyle modification is not a short-term endeavor, and maintaining a healthy weight requires sustained changes in dietary and physical activity. Intensive behavioral intervention can help modify deep-rooted behaviors and provide the support required to both initiate and maintain the behavioral changes that are needed to achieve weight loss goals.
