Why Do I Want to Eat So Unhealthy on My Period?

4 min read

Premenstrual food cravings affect an estimated 97% of menstruating individuals, with many reporting intense urges for high-carb, sugary, or salty junk food. This phenomenon often leaves people questioning, 'Why do I want to eat so unhealthy on my period?' as they struggle with seemingly uncontrollable urges for comfort foods.

Quick Summary

The desire for unhealthy food during menstruation is driven by hormonal fluctuations, particularly drops in serotonin, which lead to cravings for high-calorie items. Changes in insulin sensitivity and nutrient deficiencies also play a role, as the body seeks quick energy and minerals like magnesium. Understanding these biological and psychological factors can help you manage cravings more effectively.

Key Points

  • Hormonal Shift: Falling estrogen and rising progesterone in the luteal phase trigger increased appetite and cravings, particularly for carbohydrates and sweets.

  • Serotonin Dip: A decrease in serotonin, the 'happy hormone', prompts the body to seek high-carb foods to temporarily boost mood and combat PMS-related sadness.

  • Brain Insulin Changes: Reduced insulin sensitivity in the brain during the premenstrual phase can lead to increased hunger signals and cravings for sugary items, as the brain demands more glucose.

  • Psychological Connection: Emotional eating is common during menstruation, as people use comfort foods to cope with physical discomfort and emotional distress.

  • Nutrient Signaling: A craving for chocolate can be a sign of a magnesium deficiency, while heavy periods may cause an iron deficiency that triggers meat cravings.

  • Healthy Management: Strategies like smart snacking with whole foods, regular hydration, and gentle exercise can help manage cravings more effectively and alleviate other PMS symptoms.

The Hormonal Rollercoaster and Your Appetite

Your menstrual cycle is governed by fluctuating hormones, primarily estrogen and progesterone, which have a profound impact on your appetite and mood. In the luteal phase—the week or two leading up to your period—progesterone levels rise, while estrogen and the 'feel-good' neurotransmitter serotonin drop.

  • Serotonin Slump: With less serotonin available, your brain looks for quick ways to boost your mood. Consuming carbohydrates and sugar can temporarily raise serotonin levels, providing a brief sense of well-being. Your craving for sugary baked goods or a chocolate bar is your body’s subconscious attempt to self-medicate and lift your spirits.

  • Progesterone's Role: The rise in progesterone can also increase your overall appetite. This hormone helps prepare the uterine lining for a potential pregnancy, a process that requires extra energy. While the increase in metabolic rate during this phase is minimal, it can still signal to your brain that it needs more calories.

  • Insulin Insensitivity: A recent study found that insulin sensitivity in the brain decreases during the late luteal phase. This means your body becomes less efficient at processing sugar, leading to increased blood glucose levels and leaving your brain feeling 'hungry' for more glucose. The result is a more intense drive for sugary, energy-dense foods.

The Psychology and Physiology Behind Period Cravings

Beyond hormones, there are several other factors that explain why you may crave unhealthy food during your period. Both your mind and body are working together, often against your better judgment, to get through this uncomfortable time.

  • Emotional Eating: Many women use comfort foods to cope with the physical discomfort and emotional distress associated with PMS, such as mood swings, anxiety, or sadness. This emotional eating provides temporary relief, creating a psychological association between junk food and feeling better.

  • Nutrient Deficiencies: Specific cravings can sometimes be a sign of a nutrient deficiency. For instance, a strong craving for chocolate can signal a need for magnesium. During the menstrual cycle, the body's mineral levels can fluctuate, and reaching for a magnesium-rich food is a natural, if often inefficient, response. Similarly, heavy periods can lead to low iron, and some may unconsciously crave red meat or other iron-rich foods.

  • The Comfort Factor: For many, junk food is a learned comfort. We associate it with movie nights, celebrations, or a pick-me-up. This deep-seated emotional attachment can make it difficult to resist when we feel particularly vulnerable or in need of soothing.

Managing Unhealthy Cravings: Healthy Swaps and Habits

While period cravings are normal, consistently giving in to unhealthy options can exacerbate menstrual symptoms like bloating, fatigue, and mood swings. By understanding the 'why' behind the cravings, you can make more mindful, healthier choices. Here are some strategies for managing them effectively:

Healthy Alternatives for Common Cravings

Craving Category Unhealthy Choice (Limit) Healthy Alternative (Choose)
Sweets Sugary candy, ice cream, pastries Dark chocolate (70%+): High in magnesium to satisfy cravings healthily.
Fresh fruit: Berries or bananas provide natural sugars and fiber.
Salty Snacks Processed chips, pretzels, packaged snacks Air-popped popcorn: A whole-grain, high-fiber snack.
Nuts and seeds: Provide protein, healthy fats, and magnesium.
Carbs White bread, refined pasta Whole grains: Brown rice, oats, quinoa, or whole-wheat bread.
Legumes: Lentils and beans for stabilizing blood sugar.
Comfort Foods Fatty, greasy takeout Avocado toast on whole-wheat: Provides healthy fats and fiber.
Homemade smoothie: Packed with fruits, yogurt, and nutrients.

Actionable Steps to Take Control

Managing period cravings isn't about rigid deprivation but about making smarter choices and understanding your body's signals. Here are some practical tips to help you navigate this time of the month:

  • Prioritize Whole Foods: Focus on a diet rich in whole foods, like fruits, vegetables, lean protein, and whole grains, throughout your cycle, not just during your period. This foundation can help balance hormones and provide steady energy, reducing the intensity of cravings when they hit.
  • Snack Strategically: Instead of waiting for a craving to strike, plan for it. Having healthy, protein-rich snacks like a handful of nuts or some Greek yogurt ready can preempt an unhealthy choice.
  • Stay Hydrated: Increased water retention during your period can sometimes be mistaken for hunger. Drinking plenty of water can help with bloating and may reduce unnecessary snacking.
  • Get Moving: Regular, gentle exercise, such as walking or yoga, can help boost serotonin levels and reduce stress, addressing the emotional drivers of cravings.
  • Mindful Eating: When you do indulge, do so mindfully. Pay attention to the taste, texture, and satisfaction of your food. This helps you enjoy the treat more fully and can prevent overindulging. For more on mindful eating, consider resources from authoritative sources like the National Institutes of Health.
  • Supplement Wisely: If you suspect a specific nutrient deficiency, consider supplements. Magnesium, calcium, and B vitamins have all been linked to helping with PMS symptoms and mood regulation. Always consult a healthcare provider before starting any new supplement regimen.

Conclusion: Your Body, Your Choice

Experiencing a powerful desire for unhealthy comfort food on your period is not a sign of a lack of willpower; it is a complex biological response driven by fluctuating hormones, brain chemistry, and psychological factors. By recognizing these triggers and employing strategies like healthier food swaps, mindful eating, and regular exercise, you can manage your cravings without guilt. Listening to your body's needs and fueling it with nutrient-dense alternatives can help you navigate your menstrual cycle more comfortably and healthfully. Remember, a little indulgence is okay, but understanding the science behind the urge is the first step toward lasting change.
