A study by Stephanie Borgland found that rats eating a 'cafeteria-diet' of high-fat and high-sugar foods developed brain changes in the orbitofrontal cortex, leading to increased motivation to eat despite satiety. Obesity was also observed, highlighting the complex mechanisms behind food attraction.
A consensus among 22 nutrition researchers is that sugar-sweetened beverages increase cardiometabolic risk factors compared to equal amounts of starch. The paper also suggests that aspartame does not promote weight gain and consumption of polyunsaturated fats lowers disease risk when compared to saturated fats.

This study challenges the general view of NAMPT as an enzyme that should be boosted, and may pave the way for new treatments for obesity and metabolic disease.
Researchers discovered naturally occurring hormones 'notum' and 'lipocalin-5' that accelerate fat burning and protect against Type 2 diabetes.

Inhibiting an enzyme called soluble epoxide hydrolase may abolish this risk, suggesting a potential treatment for obesity-induced colonic inflamm...
A new study published in Arthritis Care & Research reveals that severe obesity is linked to faster progression of disability in patients with rheumatoid arthritis. Intentional weight loss may help prevent worsening disability, but unintentional weight loss can be a poor prognostic sign.
Research reveals that obesity suppresses the epithelial defense against cancer, allowing malignant cells to remain and develop tumors. Aspirin treatment enhances this defense mechanism, suggesting a potential role in cancer prevention.
A recent study found that obesity contributes to poorer outcomes in non-white patients who have hemorrhagic strokes, with African-Americans being particularly vulnerable. The research highlights the need for targeted interventions to address nutritional needs and reduce the burden of obesity on recovery following stroke.
