Fasting's Mind-Bending Effects: What Science Says

Fasting isn't just about skipping meals. It's a trend that's caught on for its health perks. But what does it do to our minds? Recent research dives into the psychological and psychiatric effects of fasting for long stretches. It's not just about the body; the brain gets a workout too. Different fasting styles exist, from time-restricted eating to religious practices like Ramadan. While the body's response to fasting is well-studied, the mind's reaction is a bit of a mystery. A recent review looked at studies from 2010 to 2025 to understand how fasting affects mood, thinking, and mental health.The review found 87 studies that fit the bill. In healthy adults, short-term fasting seemed to ease depression and stress a bit. It also gave a small boost to brain functions like planning and decision-making. Religious fasting, like during Ramadan, had similar effects, with added benefits like a sense of spiritual meaning. But it's not all good news. Fasting can also stir up trouble. Some people experienced mood swings, anxiety, and even severe mental health issues. Those with eating disorders were more likely to fixate on food and relapse into harmful behaviors. The studies varied a lot, making it hard to compare results directly. So, what's the takeaway? Fasting can be a double-edged sword. It might build mental resilience in some, but it can also pose risks for others. Future research should focus on long-term safety and use standardized measures to track mental health outcomes.
