Researchers will examine inflammatory process in obese patients to understand how it contributes to cardiovascular disease. High levels of free fatty acids in the blood stream may trigger inflammation, which increases risk of atherosclerotic disease in obese patients with diabetes.
Researchers found that subjects viewing 'before and after' ads indicated a strong anti-fat bias and believed weight is more easily controllable than those who viewed only the 'before' or 'after' pictures. The study suggests that such biases can influence further weight and eating disorder psychopathology.
Rimonabant demonstrated significant weight loss and improvement in metabolic profile in patients with obesity and untreated dyslipidemia. The drug also improved cardiovascular risk factors, including HDL-cholesterol and triglycerides, by reducing inflammation and increasing adiponectin levels.
A recent study found that college-educated Caucasian women have lower BMI levels compared to similar African American women, regardless of age or other factors. However, the study suggests that socioeconomic status may not be as protective against obesity for black women.
