These brain cells responded differently to hunger hormones and obesity-related genes. The study provides a platform for modeling complex polygenic diseases like obesity.
A new study found weight-loss surgery reduces average costs to the UK National Health Service by €2742, while gaining 0.8 life-years and 4.0 quality-adjusted life years compared to usual care. The procedure also has potential benefits in reducing obesity-related cardiovascular diseases and diabetes.
Researchers discovered that DOR protein deficiency stimulates the generation of new adipose cells and leads to a less harmful form of obesity. This type of obesity is characterized by an increase in the number of fat cells rather than their volume, which may be less susceptible to metabolic complications.
Researchers at Tufts University have identified the neural circuit in the hypothalamus that mediates leptin's anti-obesity and anti-diabetes effects. The study reveals two distinct mechanisms underlying leptin's inhibition of appetite, providing important insight into how leptin works and how resistance to it develops.
A new Northwestern Medicine study shows that screenings for diabetes and prediabetes could be improved by expanding the screening criteria to include additional risk factors. This would lead to the identification of most cases of prediabetes and type 2 diabetes, with only 23% of patients being missed.
Research found that having an evening preference is linked to a higher BMI among people with Type 2 diabetes. Participants with late breakfast times had a BMI of 28.4 kg/m^2, compared to those who ate earlier, who had a lower BMI by 0.37 kg/m^2.
A new paper challenges the concept of 'healthy obesity,' arguing that it is flawed and misleading. Researchers propose further investigation into factors such as early life events, smoking, and obesity duration to understand why some obese individuals are healthy while others develop diseases.
A comprehensive study assesses health patterns in the US, revealing wide disparities between states. The Global Burden of Disease study estimates change in disease, injuries, and risk factors from 1990 to 2016 by state.
