Intermittent Fasting Boosts Sex Drive in Male Mice Through Serotonin Reduction

A recent study has found that intermittent fasting in 24-hour cycles increases the sexual drive of male mice. Researchers attribute this effect to a reduction in serotonin levels in the brain, which occurs due to a diet-induced deficiency of tryptophan, an essential amino acid obtained through food.

The findings suggest that long-term fasting alters brain chemistry by lowering tryptophan availability, which subsequently reduces serotonin concentration. This change appears to influence sexual behavior in male mice, increasing their libido. The study highlights the potential link between dietary patterns and neurotransmitter activity but does not address whether similar effects could occur in humans. Further research is needed to explore how these findings might translate beyond animal models.
