Exercise training after bariatric surgery alters brain networks associated with food intake and energy regulation. The study found that exercise increased connectivity between the hypothalamus and sensory areas, while decreasing links to the default mode network and salience network.
UConn researchers have developed simple measurements and equations that better predict fat distribution in individuals based on their sex and ethnicity. The tools account for differences in body composition between ethnic populations and women and men, providing a more accurate assessment of obesity-related health risks.
A new survey found that nearly a third of Americans worry more about obesity due to COVID-19, with 28 million people considering weight loss methods. The survey also showed that nearly 90% with obesity have tried to lose weight at some point in their lives, but many underestimate the effectiveness of treatments like weight-loss surgery.

Initiatives targeting neighborhood environments may help prevent excess weight in children.
A recent study published in eLife found that childhood body mass index has a minimal effect on anxiety symptoms, but conflicting evidence about its impact on depressive and ADHD symptoms.

A study of over 1000 Australian adults found that people with trouble sleeping were more likely to have indicators of poor cardiometabolic health, including inflammatory markers, cholesterol, and body weight. Prioritizing a good night's sleep is crucial for maintaining good health, according to researcher Dr Lisa Matricciani.
A recent study published in Geriatrics found that age, education, social network, pain, and depression are significant predictors of physical activity in older adults. The findings suggest that modifying these factors through targeted interventions can increase physical activity levels.
A new study from the University of East Anglia found that overweight women are more likely to experience symptoms of long Covid. The research also shows that people with long Covid are much more likely to need additional and lasting NHS care than those who make a swift recovery.
Higher weight and BMI z-scores in pre-adolescence are associated with poor brain health, including structural changes and decreased connectivity. The findings provide an important mechanistic explanation for the link between childhood obesity and impaired cognitive function.
Research finds that increased body weight is associated with higher levels of inflammation, signs of gut permeability, and poorer asthma control. The study suggests that targeting the gut could be an effective treatment target for improving asthma control in patients with obesity. Weight loss may also improve symptoms for these patients.
A Rutgers study of 86,964 adults with obesity and NAFLD found that bariatric surgery reduced the risk of major cardiovascular events by 49% compared to nonsurgical care. This is significant because heart disease is a leading cause of death in the US, and NAFLD can lead to liver damage and inflammation.
A University of Gothenburg study found that severe obesity at age 18 is associated with a three- to fourfold increased risk of developing atrial fibrillation in younger middle age. The study analyzed data from over 1.7 million men in Sweden and found that higher BMI was linked to mortality risk, heart failure, and ischemic stroke.
A genetic variant associated with a 10-15% reduction in fat storage has been identified in 60% of Europeans. Researchers studied the effect of this variant in mice and found it to be linked to leanness, highlighting the complex interplay between genetics and obesity.
Researchers identified a genetic variant that predisposes people to being slim, carried by 60% of Europeans. The variant affects the amount of fat stored in the body and is associated with the biochemical signalling pathway that tells cells what nutrients are available.
