Randomised trial, 1999

Does the drop in progesterone or stress during the menstrual cycle cause chocolate and sweets cravings?

This study found no clear evidence either way. Neither progesterone nor a tranquilizer reduced chocolate or sweets craving in women with severe PMS.

Moderate study design Women with severe PMS who experienced chocolate or sweets cravings around their period

What they did

Women with severe PMS who craved chocolate or sweets tracked their cravings daily for 6 menstrual cycles. 44 women with chocolate craving and 44 with sweet craving were then randomly assigned double-blind to receive either placebo, progesterone, or alprazolam (a tranquilizer) from week 3 of the cycle through day 2 after their period, for 3 months.

What they found

Neither progesterone nor alprazolam decreased chocolate or sweets craving.

What it means for you

The two leading theories about what causes perimenstrual chocolate and sweets cravings (low progesterone or tension) are not supported by this study. The actual cause remains unclear. This study was only in women with severe PMS who craved these foods.
