Abstract：Objective To investigate the impact of 15 days of complete fasting on individuals'risk decision-making abilities and the role of physical exercise in this process.Methods Twenty-four healthy participants completed a 28-day experiment divided into baseline,complete fasting,calorie restriction,and full recovery phases.Participants were randomly assigned to a light exercise group(EL),moderate exercise group(EM),or control group(CN).Risk decision-making capacity was assessed using the Balloon Analogue Risk Task(BART),with data analyzed via Kruskal-Wallis and Friedman tests.Results Fifteen days of complete fasting did not significantly affect the participants'risk decision-making abilities.Additionally,after fasting,the moderate exercise group was more likely to make risky decisions compared to the light exercise group.Conclusion Long-term fasting has no significant impact on risk decision-making ability,but engaging in physical exercise makes people more likely to make high-risk decisions.
