Why Do Cravings Increase Before Your Period? Understanding Hormonal Hunger
Have you ever noticed that a few days before your period, you suddenly want chocolate, sweets, salty snacks, or carbohydrate-rich foods?
You are not imagining it.
Changes in appetite and food cravings are recognized symptoms of premenstrual syndrome (PMS), and research suggests that appetite and food intake can change across the menstrual cycle. These changes are particularly noticeable during the luteal phase, the part of the cycle between ovulation and the start of menstruation.
But why does this happen?
The answer involves a combination of hormonal fluctuations, changes in appetite regulation, energy needs, mood, sleep, and food-reward pathways.
What Happens to Your Appetite Before Your Period?
After ovulation, the body enters the luteal phase. During this time, reproductive hormones, particularly estrogen and progesterone, change significantly.
Research has found that food intake tends to be higher during the luteal phase than around ovulation. Some studies have also reported more frequent cravings for foods rich in carbohydrates and fat during this phase.
This does not mean every woman will experience increased hunger or cravings before every period. Menstrual cycles vary considerably between individuals, and appetite can also be influenced by sleep, stress, physical activity, eating patterns, and overall health.
1. Hormonal Fluctuations Can Influence Hunger
Estrogen and progesterone interact with the brain systems involved in appetite, eating behavior, and energy regulation.
Estrogen generally has appetite-suppressing effects, while progesterone may have appetite-stimulating effects. The changing balance of these hormones throughout the menstrual cycle can therefore influence how hungry you feel and how appealing certain foods seem.
However, it would be inaccurate to say that progesterone alone causes premenstrual cravings. Studies have produced different findings, suggesting that several biological and behavioral factors are involved.
2. Your Body May Need Slightly More Energy
Another possible explanation is a change in energy expenditure during the luteal phase.
Research has reported increases in both energy intake and energy expenditure during this phase of the menstrual cycle. Some studies have estimated that average energy intake may increase during the luteal phase, although the amount varies considerably between women.
So if you feel genuinely hungrier before your period, it may not simply be a matter of "lack of willpower." Your body's energy regulation can change throughout the menstrual cycle.
3. Why Do You Crave Chocolate and Carbohydrates?
One of the most commonly reported premenstrual cravings is for sweet or carbohydrate-rich foods.
Researchers have suggested that changes in brain reward pathways and neurotransmitters may contribute to these cravings. Food-cue studies have found evidence of greater responsiveness to highly palatable foods during the luteal phase in some women.
Carbohydrate-rich foods may also feel particularly appealing when you are tired, stressed, or experiencing mood changes.
However, the popular idea that "you crave chocolate because your serotonin is low" is too simplistic. Mood, hormones, food reward, habits, and individual preferences can all interact.
4. PMS Can Make Food More Appealing
PMS is more than just physical symptoms.
Some women experience irritability, anxiety, low mood, fatigue, sleep changes, bloating, and appetite changes in the days before menstruation.
When you are tired or emotionally uncomfortable, highly palatable foods can become more attractive because eating can provide temporary pleasure or comfort.
Recent research has also found an association between PMS and increased "hedonic hunger," which refers to wanting food for pleasure rather than simply because of physical hunger.
5. Sleep and Stress Can Intensify Cravings
Hormonal changes are only one piece of the puzzle.
Poor sleep and increased stress can make it harder to regulate appetite and may increase the desire for convenient, energy-dense foods.
If you are already experiencing premenstrual fatigue, mood changes, or disrupted sleep, cravings may feel stronger than usual.
This is why managing cravings is often more effective when you look at your whole routine, rather than focusing only on hormones.
Are Premenstrual Cravings a Sign of a Hormonal Imbalance?
Not necessarily.
Having stronger cravings before your period is relatively common and can be part of normal menstrual-cycle changes. It does not automatically mean that your hormones are "imbalanced."
In fact, research on the relationship between individual hormones and food cravings is still evolving. One small 2023 study found an inverse association between mid-luteal progesterone and premenstrual food cravings, while estradiol was not significantly associated with cravings after adjustment.
This highlights an important point: there is no single hormone that can explain every woman's cravings.
How Can You Manage Premenstrual Cravings?
The goal should not necessarily be to eliminate cravings. Instead, aim to understand them and respond to your body's needs without guilt.
Eat Regular, Balanced Meals
Skipping meals can make cravings feel much stronger later in the day.
Try to include a combination of:
Protein
Whole grains or other complex carbohydrates
Vegetables and fruits
Healthy fats
Fiber-rich foods
A balanced meal can provide better satiety than relying on sugary snacks alone.
Choose Complex Carbohydrates
Whole grains, beans, lentils, oats, brown rice, and other fiber-rich carbohydrate sources can help provide sustained energy.
The American College of Obstetricians and Gynecologists notes that a diet rich in complex carbohydrates may help reduce PMS-related mood symptoms and food cravings.
Don't Completely Ban Your Favorite Foods
Strictly avoiding chocolate or other foods you enjoy can sometimes make cravings feel even more intense.
Instead, enjoy your favorite foods in reasonable portions alongside an overall balanced diet.
Stay Hydrated
Thirst can sometimes be confused with hunger, while adequate hydration can also support normal digestion and overall well-being.
Prioritize Sleep
Maintaining a consistent sleep schedule can be particularly helpful when PMS symptoms include fatigue or mood changes. ACOG also recommends getting adequate sleep as part of managing PMS symptoms.
Track Your Cycle and Cravings
Keeping a simple record of your menstrual cycle, appetite, cravings, sleep, mood, and meals can help you identify patterns.
For example, you may discover that your cravings consistently increase three to five days before your period.
Recognizing the pattern can make the experience feel more predictable and easier to manage.
When Should You Talk to a Doctor?
Occasional premenstrual cravings are usually not a cause for concern.
However, consider speaking with a healthcare professional if your symptoms are severe, happen every month, or significantly interfere with your work, relationships, sleep, or daily activities.
Particularly intense emotional or physical symptoms may be associated with premenstrual dysphoric disorder (PMDD) or another condition that deserves proper evaluation.
It is also important to seek professional advice if changes in appetite are accompanied by unexplained weight changes, persistent digestive symptoms, extreme fatigue, or other concerning symptoms.
The Bottom Line
Increased cravings before your period can be a real biological experience, not simply a lack of self-control.
Hormonal fluctuations during the luteal phase can influence appetite and eating behavior, while changes in energy expenditure, mood, sleep, stress, and the brain's food-reward system may also contribute.
Instead of feeling guilty about premenstrual hunger, try listening to your body's signals. Regular balanced meals, adequate protein and fiber, complex carbohydrates, good sleep, hydration, and a flexible approach to favorite foods can help you navigate cravings more comfortably.
Most importantly, you do not need to fight your body every month. Understanding your menstrual cycle can help you work with it rather than against it.
