Period Cravings: Why You Crave Food Before Your Period

Cravings before your period are common, and they're linked to the premenstrual days, when hormones shift. Researchers don't know the exact cause, and the science is still developing. What we can say is that appetite changes are a recognized PMS symptom, that they vary a lot, and that giving yourself some grace is a perfectly reasonable response.

Quick summary: Appetite changes and cravings are common premenstrual symptoms. Hormones likely play a role, but the exact reasons aren't settled. Regular meals, sleep, movement, and kindness toward yourself help; severe symptoms deserve a doctor's attention.

Are cravings a real PMS symptom?

Yes. MedlinePlus lists food cravings among common PMS symptoms, alongside bloating, breast tenderness, headaches, and mood changes. The NHS lists changes in appetite or food cravings, and the Office on Women's Health lists appetite changes or cravings among emotional and mental PMS symptoms. Cleveland Clinic's luteal phase page includes "changes in your appetite" among common luteal phase symptoms.

PMS symptoms typically start one to two weeks before a period and ease once bleeding starts, according to MedlinePlus. That window overlaps with the luteal phase, the stretch after ovulation. You can read more in our luteal phase guide.

So why does it happen?

The honest answer: researchers aren't certain. The Office on Women's Health says the exact cause of PMS is unknown, but hormone changes across the cycle likely play a role. After ovulation, progesterone rises, then hormone levels fall if there's no pregnancy (Cleveland Clinic).

Some small studies hint at explanations, but none are settled:

• Late-luteal timing. A 2023 study in Nutrients (Hamidovic et al.) tracked 58 women and found that food cravings were similar across most of the cycle, but rose in the late luteal subphase, with the strongest effect in women who had both abdominal obesity and PMDD. The authors called their findings "hypothesis-generating," and noted the sample was small and cravings were self-reported.
• Other ideas. In that study, a marker of inflammation was linked to late-luteal cravings in the PMDD group only, but the sample for that analysis was tiny. It's an idea for future research, not an explanation you can lean on.

So: cravings often cluster in the days before a period, hormones are suspected, and the details are unsettled. Anyone claiming a single neat cause is overselling.

Wanting versus eating

Cravings and actual eating aren't always the same. In the Nutrients study, irritability and depression were linked to cravings, but the authors didn't tie the late-luteal increase to mood symptoms. The research on whether people actually eat more is still developing, so you shouldn't assume cravings mean you're "out of control." Your appetite may simply feel louder.

What can help

These come from health-authority advice for PMS in general, not from proof that they stop cravings:

Eat regularly

The NHS suggests a balanced diet, possibly with smaller, more frequent meals. Skipping meals can make hunger feel more intense for many people.

Think "and," not "or"

The Office on Women's Health suggests healthy foods and considering cutting back on caffeine, salt, and sugar in the two weeks before your period. MedlinePlus suggests little or no salt or sugar, plenty of fluids, and avoiding soft drinks, alcohol, and caffeine. If you want chocolate, you can have chocolate. A balanced approach beats a strict one.

Sleep and movement

Aiming for about eight hours of sleep and regular aerobic exercise throughout the month is recommended for PMS by the Office on Women's Health and MedlinePlus.

Stress care

The Office on Women's Health lists talking with friends, journaling, yoga, massage, or meditation. These help with overall PMS symptoms.

Be wary of "cycle syncing" diets

You'll see claims that you should eat certain foods in certain phases. Research on phase-based eating is limited and early, so treat any plan as an experiment. Supplements like calcium and vitamin B6 have some evidence for PMS, per the Office on Women's Health, while evidence for others is mixed. Check with a doctor or pharmacist before taking supplements.

Track it

Noticing that cravings show up on day 24 of your cycle takes some of the mystery out of it. A simple log of cravings, mood, and sleep helps you plan.

When to talk to a doctor

See a doctor or nurse if cravings come with severe mood symptoms, binge eating, or distress that affects your daily life. The Office on Women's Health lists food cravings or binge eating among PMDD symptoms, along with intense irritability, sadness, anxiety, and a feeling of being out of control. See PMS vs PMDD for more. If you ever have thoughts of harming yourself, in the US you can call or text 988 any time.

Also see a doctor about any eating that feels out of your control all month, not just premenstrually, or about big changes in appetite that don't track with your cycle.

For partners

If your partner has cravings, ask what she's in the mood for rather than deciding for her. Our period care package ideas has some starting points, and mood changes before your period explains the bigger premenstrual picture.
