Research using virtual reality shows that simply seeing a sick person can activate the brain's threat detection and trigger immune responses, even without physical contact, highlighting the brain's role in early immune preparedness.
Chronic stress can lead to increased cravings for high-calorie comfort foods, potentially contributing to obesity, as stress affects the brain's reward system, according to a study by the Garvan Institute of Medical Research. The research found that stress can override the brain's natural satiety signals, encouraging overeating. To combat stress eating, experts recommend having nutritious, protein-rich foods available, practicing mindful eating, and planning meals to avoid impulsive snacking. These strategies can help maintain energy and mood during stressful times.
A new study by Yale researchers found that obesity is associated with a diminished brain response to nutrient intake, which doesn’t recover even after weight loss. The study offers insights into why maintaining weight loss is challenging for some people and emphasizes the significant role of the human brain in obesity. The findings could help explain why it’s difficult for some to lose weight and maintain weight loss.
