It shows up around the same time every month. A few days before your period, you find yourself reaching for chocolate, the bread basket, or something sweet, and the pull feels unusually strong. If you've ever wondered why your appetite seems to shift in the back half of your cycle, you're not imagining it.
What causes period cravings?
Period cravings are driven by the hormonal shifts of the luteal phase, the roughly two weeks between ovulation and your period. As progesterone rises and estrogen dips, brain chemistry and blood-sugar regulation shift in ways that genuinely increase your pull toward sugar and carbs. The craving is a predictable response to your hormones. Understanding the mechanism is what makes it manageable.
Why do you get cravings before your period?
The biggest driver is a luteal-phase dip in serotonin, the neurotransmitter tied to mood and calm. Carbohydrate-rich and sugary foods temporarily raise serotonin, so the body reaches for a quick mood lift—a link documented in research on premenstrual carbohydrate cravings by Wurtman & Wurtman. Separately, the BioCycle Study (Agarwal et al., Clinical Nutrition ESPEN, 2023) found that higher inflammatory biomarkers in the luteal phase were associated with increased risk of moderate to severe food cravings, pointing to inflammation as an independent driver beyond serotonin alone.
Your metabolism shifts too. A 2024 study in the British Journal of Nutrition (Malo-Vintimilla et al.) found that during the luteal phase, resting metabolic rate rises by roughly 3 to 7% and sweet-taste preference increases, so your body is both burning a little more energy and primed to seek out sugar. Add the blood-sugar swings that come with rising progesterone, and the cravings make complete biological sense.
What foods do you crave before your period and why?
Most premenstrual cravings cluster around sugar, chocolate, and refined carbohydrates, and each has a reason. Carbs and sweets get reached for because of the serotonin-related effect above. Chocolate is a near-universal craving partly for the same reason and partly because it contains small amounts of magnesium, a mineral that some research suggests many women have lower levels of in the luteal phase.
Salty and high-fat foods often join the list too. A study published in Frontiers in Public Health (2025) found that higher premenstrual intake of energy-dense, fatty, and salty foods was associated with more pronounced PMS symptoms. The takeaway isn't that these cravings are bad; it's that they're your body seeking a specific physiological response.
How do you manage cravings before your period?
The most effective approach is keeping your blood sugar stable so the luteal dip-and-spike cycle stays gentler. In practice, that means eating regular meals built around protein, fiber, and healthy fats, not skipping meals, prioritizing sleep, and not over-restricting; rigid restriction tends to intensify cravings rather than quiet them.
Certain nutrients support this directly. Some research suggests magnesium may help ease the mood component that drives the reach for sweets, and chromium is a trace mineral that helps the body use insulin more effectively. A randomized, double-blind, placebo-controlled study published in Diabetes Technology & Therapeutics (Anton et al., 2008) looked at chromium and appetite.
This is part of the thinking behind Cycle Routine.
DailyBasis built its second-half formula, Balance, for the luteal phase specifically—including chromium and magnesium—so chromium and magnesium sit in the second-half formula rather than at a flat dose across the whole month, rather than as an afterthought in a one-size-fits-all daily supplement. You can see how the luteal-phase formula is built at dailybasislife.com.
Cravings before your period are one of those things that are easy to brush off as just part of being a woman. They're not random, and they're not something to push through on your own. Your body is doing something specific, and now you know what it is. We're here for all of it, every phase of the month.
