A study by German researchers found that severe weight loss in obese individuals can improve metabolic and psychological states, as well as decision-making abilities. After a 10-week low-calorie diet, participants showed reduced BMI, improved mood, and more risk-averse behavior. The study revealed that glucose metabolism (measured by HbA1c levels) became the primary predictor of risk-taking after weight loss, while mood’s influence on decision-making decreased. The findings suggest weight loss can restore glucose metabolism’s role in behavioral control. Prothom alo
