Hormonal Changes and Cravings: The relationship between hormones and specific food desires.

Writer: LætitiaLætitia

Hormonal changes play a significant role in influencing our food cravings by affecting the brain’s reward centers and altering our metabolic signals. Understanding the relationship between hormones and specific food desires can help explain why certain cravings emerge at different times and how these fluctuations impact our overall eating behavior.

Hormones and Their Impact on Cravings


Several key hormones are involved in regulating hunger and satiety, and their levels fluctuate in response to various physiological and environmental factors:

  • Cortisol: Often called the "stress hormone," cortisol is released in response to stress. Elevated cortisol levels can increase appetite and trigger cravings for high-calorie, comfort foods, particularly those rich in sugar and fat. This response is believed to be the body’s way of preparing for a fight-or-flight situation by quickly boosting energy reserves.

  • Insulin: This hormone, responsible for regulating blood sugar levels, also influences hunger. When insulin levels rise sharply—often after consuming high-glycemic foods—the resulting drop in blood sugar can lead to cravings for more carbohydrates as the body seeks to stabilize its energy levels.

  • Ghrelin and Leptin: Ghrelin is known as the “hunger hormone” because it signals the brain to increase appetite, while leptin signals fullness. When ghrelin is high or leptin is low (or when the body becomes resistant to leptin), you may experience stronger cravings. These hormones work together to regulate energy balance, and any disruption in their normal function can result in increased hunger and specific food cravings.

  • Sex Hormones (Estrogen and Progesterone): In women, the menstrual cycle brings about predictable fluctuations in estrogen and progesterone. Many women report specific food cravings during the premenstrual phase—often for sweets or carbohydrates—which are linked to these hormonal changes. For example, a drop in estrogen and a rise in progesterone during the luteal phase may lead to increased appetite and a desire for comfort foods that provide a quick energy boost or a mood lift.



Examples of Hormonal Influences on Food Cravings


  • Premenstrual Syndrome (PMS): During the latter part of the menstrual cycle, many women experience cravings for sugary or starchy foods. This can be due to the combined effects of rising progesterone and fluctuating estrogen levels. These hormones can alter neurotransmitter activity, leading to mood changes and a desire for foods that offer a temporary sense of well-being.

  • Pregnancy: Hormonal shifts during pregnancy are dramatic. Many pregnant women experience cravings or aversions to certain foods. While these cravings might be influenced by a need for specific nutrients, they are also a response to the significant hormonal changes that occur during pregnancy. For example, some women may crave sour or tangy foods, which could be linked to changes in taste perception and digestive comfort.

  • Stress Response: Under chronic stress, elevated cortisol can prompt a cycle where the body craves high-energy foods. This can lead to overeating and a preference for foods that are quick sources of energy—often at the expense of nutritional balance. These cravings are a survival mechanism but can be maladaptive in modern environments.

Why Understanding These Interactions Matters


Recognizing the impact of hormonal fluctuations on food cravings is crucial for several reasons:

  • Improved Nutritional Strategies: By understanding that cravings might be hormonally driven rather than a sign of true hunger, individuals can adopt strategies such as waiting 10-15 minutes before giving in to a craving or choosing healthier alternatives that satisfy the same craving. For instance, instead of indulging in high-sugar snacks during PMS, opting for fruit with a bit of nut butter can provide a more balanced nutritional profile.

  • Stress Management: Realizing that stress-induced cravings are linked to cortisol can encourage the use of stress reduction techniques like mindfulness, meditation, or physical activity to help modulate hormone levels and reduce the reliance on food for comfort.

  • Hormonal Balance: In some cases, dietary adjustments or supplementation (under professional guidance) might help balance hormone levels. This can lead to a reduction in extreme cravings and promote overall well-being.

  • Mindful Eating Practices: Understanding these hormonal influences encourages a more mindful approach to eating. Instead of viewing cravings as a weakness or failure, they can be seen as signals from the body that might require attention or adjustment in lifestyle, sleep, stress management, or even meal composition.



Check yourself regularly


Hormonal changes are a natural part of life that significantly influence our eating behaviors and cravings. By exploring the relationship between hormones such as cortisol, insulin, ghrelin, leptin, estrogen, and progesterone, we gain insight into why we might crave certain foods at specific times. This understanding can empower individuals to make more informed decisions about their diets, manage stress more effectively, and ultimately foster a healthier relationship with food. Investing time in understanding these nutrient-hormone interactions not only contributes to better health outcomes but also provides a pathway toward a more balanced, comfortable future where food choices support overall well-being rather than undermine it.
