The findings suggest that models can be built to predict diabetes risk, allowing clinicians to connect patients with weight loss or smoking cessation programs.
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.
Rates of complications, death, and subsequent surgery were similar for gastric bypass and sleeve gastrectomy in adolescents with severe obesity. Adolescents who underwent sleeve gastrectomy had lower emergency room visits and hospital admissions compared to those who had gastric bypass surgery.
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 study by Okayama University researchers found that neuromedin U (NMU) is involved in metabolic processes but its 'anti-hunger' function may not be crucial for rats. Unlike mice, NMU expression is restricted in the rat brain and does not suppress feeding behavior.

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.
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.
A recent UK-based experiment found no significant change in the overall number of calories purchased when food and drink labels showed physical activity calorie-equivalent values. The study suggests that PACE labelling may not be effective in reducing energy intake, contradicting previous expectations.
