PMS Cravings: Causes & what really helps

What happens in the body: Cravings have a reason

Cravings before your period are not a lack of discipline, but a measurable physical reaction. In the second half of your cycle, the luteal phase after ovulation, your hormone balance shifts, and this directly affects appetite and cravings. Three mechanisms work together:

• Serotonin decreases: Towards the end of the luteal phase, estrogen, and with it serotonin, your mood and satiety messenger, drop. Carbohydrates and sweets temporarily increase serotonin levels. Reaching for chocolate is therefore partly an attempt by the brain to regulate itself.
• Progesterone increases: The increased progesterone in the luteal phase stimulates metabolic processes and increases energy requirements. The body accordingly demands more replenishment.
• Resting metabolic rate increases: Studies show that the basal metabolic rate slightly increases in the luteal phase. On average, women consume about 180 calories more per day during this phase. So, a little more hunger before your period is physiologically completely normal.

In addition, there is the so-called hedonic component: Imaging studies show that the reward center in the brain reacts more strongly to palatable foods in the luteal phase. Eating for pleasure, not out of hunger, is therefore harder to control during this phase.

Why sweets and carbohydrates in particular?

The combination of decreasing serotonin and higher energy requirements explains why cravings are usually directed at sugar and carbohydrates, not broccoli. Sugar provides quick energy and briefly lifts the mood. The catch: Highly sugary snacks cause blood sugar to spike and then crash, triggering the next craving. This rollercoaster can be broken.

Are cravings exacerbated by PMS?

Yes. Women with pronounced premenstrual syndrome (PMS) report strong cravings significantly more often and eat measurably more in the luteal phase. In one study, energy intake in women with PMS during this phase was around 2,200 calories per day compared to about 1,880 without PMS. So, if your cravings are particularly intense and accompanied by irritability, low mood, or breast tenderness, PMS is often behind it.

What really helps against cravings before your period

The goal is not to suppress cravings with willpower, but to defuse the triggers. These strategies are best supported by evidence:

• Keep blood sugar stable: Opt for complex carbohydrates like whole grains, legumes, and oats instead of fast sugars. They provide the same serotonin effect, but without the crash afterward.
• Protein with every meal: Protein keeps you full longer and dampens hunger spikes. Good sources include eggs, fish, legumes, tofu, nuts, and yogurt.
• Eat regularly: Long meal breaks intensify cravings. Three meals plus planned snacks keep blood sugar more stable than spontaneous snacking.
• Enjoy consciously instead of forbidding: Consciously eating a piece of good chocolate often satisfies the craving better than strict prohibition, which later leads to overeating.
• Regulate sleep and stress: Lack of sleep and stress further increase hunger and cravings. Exercise, sufficient sleep, and relaxation indirectly contribute here.

What micronutrients can and cannot do

For magnesium and vitamin B6, the study situation is limited and inconsistent. A small randomized study found a small effect for the combination of 200 mg magnesium and 50 mg vitamin B6, mainly related to tension and mood, not specifically to cravings. An overview article from 2025 classifies the evidence for nutritional supplements for PMS as weak overall. Micronutrients can supplement a balanced lifestyle, but do not replace it, and they are not a reliable means of stopping cravings.

When you should take a closer look

Cravings before your period are normal. However, medical clarification is advisable if:

• the cravings are so strong that you regularly lose control over eating or have binge eating episodes,
• the cravings are accompanied by pronounced PMS symptoms or severe mood swings,
• you suspect an eating disorder,
• signs of a hormonal imbalance such as irregular cycles or severe exhaustion occur concurrently.

In these cases, it is worthwhile to have your hormonal situation assessed instead of struggling with cravings alone.

Conclusion

Food cravings before your period are a normal, hormonally controlled reaction: Decreasing serotonin, increasing progesterone, and a higher energy requirement in the luteal phase make reaching for sweets understandable, not a sign of weakness. Understanding this can help you deal with it more calmly.

Instead of fighting against your body, it helps to defuse the triggers: keep blood sugar stable, eat enough protein, have regular meals, and consciously enjoy instead of forbidding. If the cravings are particularly strong or accompanied by severe PMS, a closer look at your hormones is worthwhile.
