Diet and Exercise May Slash Depression Symptoms by 40%, Study Finds

A new study from Deakin University has found that simple changes to diet and exercise can cut depression symptoms by around 40%. The research suggests these lifestyle adjustments could offer a practical option for people reluctant to try medication or therapy. The findings also reinforce the link between physical health and mental wellbeing. The study focused on improving overall health rather than weight loss. Participants in the lifestyle group ate better-quality food and reduced their intake of processed items. Sessions were held online, making the program easy to access.

Earlier research had already hinted at a connection between flexibility and life expectancy. This time, however, the team compared lifestyle changes with cognitive behavioural therapy (CBT). Both approaches led to similar reductions in depressive symptoms. Experts pointed out that combining lifestyle changes with therapy might work even better. But they also noted some limitations—the study mainly involved middle-aged women and only looked at short-term effects.

The results suggest that diet and exercise could play a bigger role in managing depression. For those avoiding medication or therapy, these changes may provide a helpful alternative. Further research will be needed to explore long-term benefits and broader age groups.
