Despite obesity specialists’ enthusiasm for the drug’s potential, they also described major barriers to uptake and accessibility. Those barriers, they say, are rooted in the sordid legacy of weight-loss drugs and outdated notions of obesity (JAMA)

Gut microbiota changes after metabolic surgery in adult diabetic patients with mild obesity: a randomised controlled trial
This was the first RCT studying composite clinical, analytic, and microbiome changes in T2DM patients with class 1 obesity after RYGB versus standard medical therapy. The remarkable phenotypic improvement after surgery occurred concomitantly with changes in the gut microbiome, but at a lower level (Diabetology & Metabolic Syndrome)
Obesity in Patients with Type 1 Diabetes: Links, Risks and Management Challenges
This review, by gathering current evidence, highlights the need of solid knowledge in all facets of the treatment of patients with obesity and T1D that can only be obtained through high quality well-designed studies (Diabetes, Metabolic Syndrome and Obesity)
Ethnicity-specific BMI cutoffs for obesity based on type 2 diabetes risk in England: a population-based cohort study
We aimed to prospectively identify ethnicity-specific BMI cutoffs for obesity based on the risk of type 2 diabetes that are risk-equivalent to the BMI cutoff for obesity among White populations (≥30 kg/m2). (Lancet)
Reducing weight and BMI following gestational diabetes: a systematic review and meta-analysis of digital and telemedicine interventions
In summary, this systematic review demonstrated the point estimate of the effect of the intervention on weight and BMI has potential to be clinically relevant but was not statistically significant (BMJ Open, Diabetes Research & Care)
Effect of Continued Weekly Subcutaneous Semaglutide vs Placebo on Weight Loss Maintenance in Adults With Overweight or Obesity
Among adults with overweight or obesity who completed a 20-week run-in period with subcutaneous semaglutide, 2.4 mg once weekly, maintaining treatment with semaglutide compared with switching to placebo resulted in continued weight loss over the following 48 weeks (JAMA)
Global prevalence of metabolic syndrome among patients with type I diabetes mellitus: a systematic review and meta-analysis
Nearly a quarter of the type 1 diabetes mellitus patients were affected by metabolic syndrome. Therefore, more attention should be paid to the prevention and control of the epidemic and for the reduction of the morbidity and mortality associated with metabolic syndrome among type 1 diabetes mellitus patients (Diabetes and Metabolic Syndrome)
Once-Weekly Semaglutide in Adults with Overweight or Obesity
In participants with overweight or obesity, 2.4 mg of semaglutide once weekly plus lifestyle intervention was associated with sustained, clinically relevant reduction in body weight (NEJM)
Insulin-Stimulated Muscle Glucose Uptake and Insulin Signaling in Lean and Obese Humans
We suggest that reduced muscle glucose uptake in obesity is not due to defects in the insulin signaling pathway at the level of Akt/AS160, which suggests there remain significnt gaps in our knowledge of muscle insulin resistance in obesity. Our data imply that models of acute lipotoxicity don’t replicate the pathophysiology of obesity (Journal of Clinical Endocrinology & Metabolism)
Durability of glycaemic control in type 2 diabetes: A systematic review and meta‐analysis for its association with body weight changes
Modest weight loss with a goal of 2‐3% of body weight should be recommended to improve therapeutic durability and prevent beta‐cell deterioration (Diabetes, Obesity and Metabolism)
A Randomized, Controlled Trial of Liraglutide for Adolescents with Obesity
In adolescents with obesity, the use of liraglutide (3.0 mg) plus lifestyle therapy led to a significantly greater reduction in the BMI standard-deviation score than placebo plus lifestyle therapy (NEJM)
Time Course of Normalization of Functional β-Cell Capacity in the Diabetes Remission Clinical Trial After Weight Loss in Type 2 Diabetes
A gradual increase in assessed functional β-cell capacity occurred after weight loss, becoming similar to that of NDC group participants by 12 months. This result was unchanged at 2 years with continuing remission of type 2 diabetes (Diabetes Care)
Long-Term Weight Loss With Metformin or Lifestyle Intervention in the Diabetes Prevention Program Outcomes Study
Among persons with weight loss of at least 5% after 1 year, those originally randomly assigned to metformin had the greatest loss during years 6 to 15. Older age and the amount of weight initially lost were the most consistent predictors of LTWL maintenance (Annals of Internal Medicine)
Adiposity and Diabetes Risk in Adults with Prediabetes: Heterogeneity of Findings Depending on Age and Anthropometric Measure
The association of central adiposity with type 2 diabetes incidence was lower for people in the older age group than for those in the younger age group (Obesity)
Uptake and retention in group-based weight-management services
Literature review and behavioural analysis (Public Health England)
Childhood obesity: Time for action
Current estimates suggest that nearly a third of children aged 2 to 15 in the UK are overweight or obese. These children and young people are becoming obese at an earlier age and staying obese for longer. The personal cost for children living with a lifetime of obesity is immense and they are more than twice as likely to die prematurely as a result (Parliament, UK)
Comparison of Surgical and Medical Therapy for Type 2 Diabetes in Severely Obese Adolescents
Compared with medical therapy, surgical treatment of severely obese adolescents with type 2 diabetes was associated with better glycemic control, reduced weight, and improvement of other comorbidities (JAMA Pediatrics)
Lifestyle Intervention and Medical Management With vs Without Roux-en-Y Gastric Bypass and Control of Hemoglobin A1c, LDL Cholesterol, and Systolic Blood Pressure at 5 Years in the Diabetes Surgery Study
In extended follow-up of obese adults with type 2 diabetes randomized to adding gastric bypass compared with lifestyle and intensive medical management alone, there remained a significantly better composite triple end point in the surgical group at 5 years. However, because the effect size diminished over 5 years, further follow-up is needed to understand the durability of the improvement (JAMA)
Body mass index and all-cause mortality among type 2 diabetes mellitus patients: Findings from the 5-year follow-up of the MADIABETES cohort
In an outpatient T2DM Mediterranean population sample, low BMI predicted all-cause mortality only in males (European Journal of Internal Medicine)
Obese, overweight with risk factors: liraglutide (Saxenda)
This evidence summary discusses 4 randomised controlled trials (RCTs) in adults who were obese or overweight (BMI 27 kg/m2 or above) with a variety of weight-related comorbidities including dyslipidaemia, hypertension, type 2 diabetes and obstructive sleep apnoea (NICE)
