A new poll found that 83% of older adults believe health insurers should cover medications to help people with obesity manage their weight. Nearly as many, 76%, also believe Medicare should cover these drugs, which are currently not covered under law.
A Northwestern University study found that nearly two-thirds of patients discontinue or change their medication within a year, highlighting the need for better understanding of barriers to treatment adherence. The high discontinuation rate for GLP-1 RAs may be due to gastrointestinal side effects.
Researchers found that switching fruit flies to a low-calorie diet extends their lifespan, even in old age. This study suggests that obese humans may benefit from reducing calorie intake in old age, as it can dramatically change their metabolisms and extend their lives.
A phase 3 trial found that tirzepatide promotes additional weight loss and preserves metabolic health when continued, but discontinuation leads to significant weight regain. Researchers suggest chronic treatment may be necessary for sustained weight loss and improved cardiometabolic risk factors.
Continued treatment with tirzepatide maintained and augmented initial weight reduction in adults with obesity. Withdrawing tirzepatide led to substantial regain of lost weight in a randomized clinical trial involving 670 participants.
A large cohort of adolescents found high BMI in late adolescence is associated with early CKD in young adulthood. High-normal BMI and severe obesity also increased the risk of developing CKD.

The study also revealed changes in gut microbial composition, with an increase in Bifidobacterium and a decrease in Collinsella, opposite to what has been seen in overweight humans.
Researchers found an epigenetic signature in cheek cells of obese twins that differs from their thinner siblings, suggesting a susceptibility to obesity may be written into molecular processes. The discovery could lead to a simple cheek swab test for an obesity biomarker and enable earlier prevention methods.

The findings suggest that enhancing sulfation may improve the barrier function of epithelial tissues, providing relief against intestinal inflammation.
A new study analyzing English primary care records found that hypertension, obesity, diabetes, and low HDL cholesterol confer a higher risk of dementia in South Asian and Black people compared to White individuals. The results suggest tailored dementia prevention efforts should be targeted towards minority ethnic groups.
A new study found that pre-pregnancy obesity is a primary driver of future cardiovascular disease risk, rather than pregnancy complications. The research followed 4,216 individuals from early pregnancy to postpartum and found those with overweight or obese BMI had a higher risk of developing hypertensive disorders during pregnancy.
Research found that poor sleep quality is associated with less muscle strength and mass, more body fat, anxiety, and depression in obese older people. The study emphasizes the importance of addressing sleep quality to prevent negative health outcomes in this population.

Researchers discovered five types of macrophages in fat tissue, with one subtype promoting inflammation and another quelling it. The findings challenge the long-held assumption that pro-inflammatory macrophages are solely responsible for obesity-related inflammation.
Research reveals that low muscle mass is associated with a two-fold risk of death from cardiovascular disease in individuals with diabetes. The study found that body composition, not just weight loss, plays a crucial role in managing weight in people with diabetes.
A UCLA-led team has discovered the nerve supply that activates brown adipose tissue, a potential key to treating obesity. The study found nerve branches in all eight cadavers dissected, which may lead to using nerves to stimulate BAT activity for weight loss.
A study published in Diabetes Care found that obesity, hypertension, and dyslipidemia alter cardiac energy production by interfering with metabolic substrate uptake. The research reveals early changes in apparently healthy middle-aged individuals, highlighting the importance of identifying mechanisms involved in heart disease onset.
Studies show that people with metabolically healthy obesity (MHO) have a 50% increased risk of coronary heart disease, despite not exhibiting metabolic complications. This raises questions about the validity of the MHO concept.
