Weight Loss May Improve Decision-Making and Mood in Severely Obese People: Study
Advertisement
A recent Clinical Nutrition study examined how significant weight loss in highly obese individuals influences their metabolism, psychological state, and decision-making processes.
Research shows that metabolic signals, like blood glucose levels, have been essential for survival, influencing decisions on territory and mating by indicating energy needs. Glucose helps the brain gauge if more resources are required, and mood also affects decision-making.
Emotional eating, aimed at improving mood, often leads to high-calorie food overconsumption and increased obesity risk. Obesity disrupts metabolism and raises blood glucose levels. However, there is limited research on how restoring glucose function and mood might affect decision-making.
The study explored how metabolic and psychological factors affect risky decision-making in obese individuals and examined the impact of weight loss on these decisions. Participants engaged in a computerized gambling task to assess risk propensity, with HbA1c levels and mood measured using the PANAS questionnaire. It was hypothesized that risk-taking would be positively correlated with BMI and that HbA1c would become a stronger predictor of risk propensity after weight loss.
