Saffron (Crocus sativus) has been investigated for its potential role in supporting weight loss, primarily due to its effects on mood and appetite regulation. Several small clinical studies suggest that saffron extract may help reduce snacking and curb appetite, potentially leading to modest weight loss. The proposed mechanism involves saffron's impact on neurotransmitters, particularly serotonin. By enhancing serotonin activity, saffron is thought to alleviate emotional eating and cravings, which are common barriers to successful weight management.

A notable randomized, double-blind, placebo-controlled study published in 2010 found that overweight women taking a saffron extract supplement experienced a significant reduction in snacking frequency and reported greater feelings of satiety compared to the placebo group. However, actual weight loss in these studies was generally modest (often less than 2 kilograms over 8 weeks). While these findings are promising, the studies conducted so far have been small, short-term, and sometimes industry-funded, raising concerns about bias and reproducibility.

Historically, saffron has not been widely used in traditional medicine systems specifically for weight loss, but rather for its mood-enhancing and digestive properties. Therefore, the justification for saffron’s use in weight management is primarily rooted in emerging scientific research rather than longstanding traditional practice. Larger and longer-term clinical trials are needed to fully establish saffron’s effectiveness and safety for weight loss.
