Intermittent Fasting and Women's Cycles: Understanding the Impact and Considerations-VPA Australia

Intermittent fasting (IF) has gained popularity as a dietary approach for weight management and overall health. However, women may wonder how IF affects their bodies, specifically during different phases of their menstrual cycles. While research on this topic is limited, it is essential to understand the potential impact and considerations for women practicing intermittent fasting throughout their cycles. 

In this article, we will explore the relationship between intermittent fasting and women's menstrual cycles, shedding light on the potential benefits and addressing important considerations for women who choose to incorporate fasting into their lifestyle. 

Understanding the Menstrual Cycle

The menstrual cycle consists of four phases: menstruation, the follicular phase, ovulation, and the luteal phase. Hormonal changes occur throughout thesefourphases, influencing energy levels, hunger, and overall well-being. Estrogen and progesterone levels fluctuate, leading to changes in metabolism, insulin sensitivity, and nutrient requirements.  

With this knowledge, a one-way approach on IF would not be advisable throughout a woman’s cycle to address the needs of the body. 

Intermittent Fasting and Menstrual Phases

  • Menstruation:During this phase, some women may experience increased hunger and cravings. It is essential to listen to your body's needs and provide adequate nourishment. Experimenting with a modified fasting approach, such as shorter time-restricted eating (e.g., shorter fasting windows) or focusing on nutrient-dense foods, may be beneficial. 

  • Follicular Phase:Estrogen is on the rise and results in energy levels being higher during this phase, and the body's sensitivity to insulin may increase. This phase is suitable for implementing intermittent fasting, as the body may have a better capacity to handle fasting periods. 

  • Ovulation:Ovulation typically occurs in the middle of the menstrual cycle. Some women may experience increased energy and improved mood. Adjusting fasting protocols, such as lengthening the feeding window or incorporating more nourishing meals, can support overall well-being. 

  • Luteal Phase:The luteal phase is characterized by hormonal changes, which can lead to cravings and fluctuations in mood. It is important toprioritise balanced nutrition and consider adjusting fasting protocols to accommodate individual needs during this phase. 

Important Considerations for Women

  1. Individual Variations 

Every woman's body is unique, and responses to intermittent fasting may vary. It is crucial to pay attention to your body's signals, adjust fasting protocols accordingly, and consult a healthcare professional if needed. 

  1. Nutrient Adequacy 

Regardless of the fasting approach, it is essential toprioritise nutrient-dense foods to meet the body's nutritional needs throughout the menstrual cycle. Ensure sufficient intake of macronutrients, vitamins, and minerals. 

  1. Health Conditions 

Women with specific health conditions, such aspolycystic ovary syndrome (PCOS) or irregular periods, should consult their healthcare provider before incorporating intermittent fasting into their lifestyle. 

  1. Stress Management and Self-Care 

Hormonal changes during the menstrual cycle can impact stress levels. Practicing stress management techniques,prioritising sleep, and engaging in self-care activities can contribute to overall well-being and support hormonal balance. 

Some products we recommend

  • Harmony Tea– Harmony tea is a perfect blend of herbs and 100% organic ingredients to promote relaxation and improve the quality of your sleep as well as enhance your mood throughout the day. 

  • Multi Greens– Multi Greens is a nutritious and tasty blend of Super Greens packed with Wheat Grass, Barley Grass and Spirulina. It ishigh in vitamins, minerals, proteins, enzymes and antioxidants that can ensure optimal cell function and effective protein and nutrient absorption. 

  • WPI/WPC -VPA Whey Protein is an excellent source of high-quality proteins.Proteins make it easier to cope with fluctuating amounts of blood sugar, as it helps to consume glucose gradually in the body.Fibre has a similar impact too. That is why eating protein andfibre helps to keep the level of blood sugar in check and gives a menstruating woman constant energy. 


Intermittent fasting can be a viable dietary approach for women, but it's important to consider the potential impact on different phases of the menstrual cycle. Each phase brings unique changes in hormonal balance and metabolic responses. 

Listening to your body, adjusting fasting protocols when necessary, andprioritising nutrient-dense meals are key considerations for women practicing intermittent fasting.
