Saffron itself does not burn fat or melt away pounds. However, several scientific studies have shown that the spice does help curb cravings and regulate blood sugar. Both of these effects can encourage weight loss by limiting how frequently you feel the need to snack. Some studies looking at its effects on metabolic disorders and type 2 diabetes also note that participants lose about 1” of waist circumference on average, even when there’s no change to BMI. Saffron’s impacts on mood and depression can also lead to weight loss in some people — when our mood improves, we snack less and move more.
