Weight loss impacts risky decisions in obesity
Risky decision-making is influenced by an individual’s psychological and metabolic condition. People with obesity not only exhibit changed risk behaviors but also experience metabolic and psychological issues. This study examined whether significant weight loss in individuals with severe obesity would 1) Normalize their psychological and physiological states and 2) Modify their decision-making behaviors. Before and after a 10-week weight reduction program, Keweloh et al. (2024) investigated the impact of glycated hemoglobin (HbA1c) levels and mood on risk behaviors in a sample of 62 individuals with obesity (41 women; BMI, 46.5 ± 4.8 kg/m²; age, 44.9 ± 14.7 years). The intervention led to a decrease in participants’ risk behaviors, significantly correlated with changes in BMI. Before the intervention, mood was a significant predictor of decision-making, while HbA1c was not. After weight loss, HbA1c became a significant predictor, whereas mood no longer had this effect. These findings can help direct the development of weight reduction intervention techniques and improve knowledge of the psychological and physiological variables influencing dangerous decision-making in severe obesity.
