In a world where wellness trends often seize the spotlight, the allure of fasting has sparked intrigue, particularly regarding its purported mental health benefits.

Advocates laud its benefits, citing improved mood and physical health, yet researchers remain skeptical, as they note the nuanced interplay between fasting, mental health and individual variability.

Fasting, particularly intermittent fasting, has gained traction as a mindful dietary approach, with proponents asserting its potential to boost mental well-being.

However, studies have presented a complex narrative, showcasing both positive and adverse effects on the emotional states of its practitioners.

Clifford Feldman, M.D., medical director at Solace Treatment Center, has pointed out the intricate relationship between fasting and mental health.

"Fasting can have a variety of effects on mental health, depending on the length of the fast, the frequency of fasting and an individual's overall health and lifestyle," Feldman explained, according to Very Well Mind.

While acknowledging research indicating heightened symptoms of depression and anxiety with short-term fasting, Feldman noted potential mood enhancement with appropriate management.

Echoing this sentiment, Ila Dayananda, M.D., M.P.H., of Oula Health, stressed the contextual nature of fasting's impact. 

For Dayananda, the varying fasting durations and methodologies may yield different outcomes, so people should be careful not to engage in prolonged or extreme fasting as this could lead to potential mood disturbances.

Furthermore, insights into fasting's influence on brain function add layers to the discourse.

Dayananda said fasting has a multifaceted impact on neurotransmitter levels and cellular stress responses.

"By promoting ketone production, fasting provides an alternative energy source for the brain, which may enhance cognitive function and protect against neurodegenerative diseases," Dayananda reportedly said.

On the other hand, Feldman stated that neurogenesis and heightened levels of brain-derived neurotrophic factor (BDNF) can contribute to cognitive improvement and stress resilience.

Despite emerging evidence suggesting fasting's efficacy in alleviating symptoms of anxiety and depression, caution prevails within psychiatric circles.

Ozan Toy, M.D., of Telapsychiatry, opined that there is a need for more robust research before advocating fasting as a treatment mode for mental health disorders.

In essence, while fasting holds promise as a holistic health strategy, its ramifications on mental well-being warrant comprehensive evaluation, according to Toy.
