A new study analyzed weight changes and their impact on lung function over a 20-year period, finding that moderate or high weight gain accelerates decline. Weight loss attenuates lung function decline in obese individuals, while maintaining low weight is crucial for preventing chronic respiratory diseases.
A multi-site study found that intensive behavioral therapy (IBT) combined with liraglutide 3.0 mg produced clinically-meaningful weight loss in patients with obesity, resulting in improvements in quality of life and cardiometabolic risk factors. The treatment approach appears to have complementary mechanisms of action.
A new disease classification system for obesity is proposed by researchers, replacing the current BMI-based diagnosis. The ABCD system has four domains: pathophysiology, body mass index classification, complications, and complication severity. This new framework aims to provide a more nuanced understanding of obesity as a chronic disease.

A large study of over 1 million women found that obesity in midlife increases the risk of dementia later in life, while poor diet and lack of exercise are not. The study also revealed short-term associations between these factors and dementia risk may be due to early symptoms of dementia.
A study led by ISGlobal found that living near green spaces reduced the risk of excess weight and obesity in women. Genetic predisposition and gene-environment interactions also played a role in the association.
The global food system has led to an intersection of undernutrition and overweight in low- and middle-income countries. More than a third of these countries face the double burden of high levels of both, primarily due to changes in food systems and increasing availability of ultra-processed foods.
Researchers found that labelling food with the amount and type of exercise needed to burn off its calories can lead to a reduction in daily calorie intake. PACE (Physical Activity Calorie Equivalent) labelling was associated with an average reduction of 65 fewer calories per meal, and up to 200 calories less per day.
A study presented at EuroEcho 2019 found that bariatric surgery significantly improved subclinical heart function, reversing abnormal heart structure and function in obese individuals. The surgery also led to improvements in type 2 diabetes, hypertension, and dyslipidaemia, resulting in a lower risk of cardiovascular disease.

A recent study found that resistance exercise, alone or combined with aerobic exercise, effectively reduces weight loss-induced decreases in hip bone density. The study suggests that incorporating resistance exercise into weight loss regimens can help protect against bone loss in older adults with obesity.
Patients with excess weight experience predominantly negative interactions during clinical consultations, often feeling judged and dismissively told to lose weight. Supportive language and approach are essential in these conversations to promote a positive experience and encourage healthy behavior change.
A recent study examining the potential link between traffic-related air pollution and obesity found a significant association with higher BMI in Mexican American women. In contrast, exposure to higher traffic pollution was linked to lower BMI in men, but not an increase.
A new study found that Class I drug treatment showed increased rates of AFib reoccurrence in obese patients compared to non-obese patients. The study suggests that obesity hinders the effectiveness of these medications, which could impact ethnic minority populations who are more likely to experience obesity and have poorer outcomes.
A Scripps Research study found that blocking the kappa opioid receptor while on a restricted-calorie diet resulted in significant weight reductions. Blocking this receptor may be a potential treatment approach for obesity.
Scientists at University of Utah Health have discovered new genetic elements that could help control obesity and metabolic disorders. Hibernating mammals have evolved short non-coding DNA snippets near genes linked to obesity in humans.
