PMS cravings: definition and meaning

PMS cravings are strong urges to eat particular foods, most often chocolate, sweets, salty snacks or carbohydrates, in the week or so before a period. They are linked to the luteal-phase rise in progesterone and appetite, falling estrogen, and dips in serotonin. Cravings are common, usually ease once bleeding starts, and are not a lack of willpower.
Why cravings show up before your period
- More energy burned: resting metabolism rises slightly in the luteal phase, by roughly 2 to 10% in studies, so appetite goes up.
- Progesterone: tends to increase hunger, while estrogen, which dampens appetite, falls.
- Serotonin: carbohydrates can briefly lift serotonin, which may explain the pull toward sweet and starchy comfort food when mood dips.
- Stress and tiredness: poor premenstrual sleep raises hunger hormones.

Cravings and mood
Cravings often arrive together with low mood, irritability or anxiety in PMS. Noticing that they appear on the same cycle days can take away guilt: it is your hormones, not a failing. If eating feels out of control or tied to distress, a doctor or eating disorder service can help.
Frequently asked questions
How many days before a period do cravings start?
Usually 3 to 7 days before, sometimes from ovulation. They typically fade within a day or two of bleeding.
Are PMS cravings a sign of a deficiency?
Usually not. Chocolate cravings are sometimes linked to magnesium, but evidence is weak. Hormones and mood explain most cravings.
