Preclinical studies and clinical trials show that intermittent fasting has broad-spectrum benefits for many health problems, including obesity, diabetes, cardiovascular diseases, cancer and neurological disorders. Therefore, intermittent fasting has become an increasingly popular method in the pursuit of health and wellness. Although this nutrition method is recommended by experts, there is an important detail you should pay attention to in intermittent fasting: The difference between men and women! Metabolic differences between men and women are an important factor shaping the intermittent fasting experience. In particular, women’s hormonal balance plays an important role in intermittent fasting; especially during menopause. This issue is on our radar!
What are the main differences in men and women metabolism?
First of all, let’s make it clear: The differences in metabolism between men and women stem from their hormonal structures. Women have cyclical changes in hormones such as estrogen and progesterone. These cycles are periodic hormonal changes known as the menstrual cycle. These cyclical changes in estrogen and progesterone levels affect women’s metabolic processes. For example, estrogen levels increase during ovulation and can accelerate metabolism, thus increasing energy expenditure. However, the thickening of the uterine lining and preparation for pregnancy under the influence of progesterone can slow down metabolism. All of these changes affect energy metabolism and fat storage processes. On the other hand, since men do not have menstrual cycles, their metabolic processes are more stable, and the effects of their hormones are naturally less variable.
Menopause and Its Effects on Metabolism
Experts emphasize the importance of adopting a cyclic approach to nutrition and intermittent fasting during the menopausal period for women. Managing metabolic changes skilfully is crucial for longevity. But what about women in the postmenopausal period? It’s stated that women in the postmenopausal period can also focus on cyclic nutrition and intermittent fasting to enhance their health and lifespan. Cyclic nutrition remains important.
Menopause marks a significant milestone in women’s lives, often characterized by hormonal fluctuations. Particularly, the decrease in estrogen levels slows down metabolism and affects body composition. There might be an increased tendency for fat storage and muscle mass loss. Therefore, it’s important for women in menopause to carefully apply intermittent fasting.
What should women do during the perimenopausal period?
What is perimenopause? It refers to the period when women begin to transition into menopause but their menstrual cycles have not completely stopped. This period typically starts in the 40s or 50s and can last for several years before menopause. During perimenopause, hormonal changes occur, and menstrual patterns usually become irregular. Common symptoms during this period include hot flashes, mood swings, insomnia, and other menopausal symptoms.
Intermittent fasting can help alleviate or manage these types of symptoms experienced by women during the perimenopausal period. For example, intermittent fasting can help control weight gain and support weight loss by regulating metabolism. Additionally, some research suggests that intermittent fasting may reduce hot flashes and improve cognitive function. However, since every woman’s body composition and response are different, it’s not possible to guarantee the same results for everyone. Therefore, women in the perimenopausal period should consult with a healthcare professional before starting intermittent fasting or making any dietary changes.
What should women with thyroid issues pay attention to during intermittent fasting?
If you have thyroid issues, there are several things to consider during intermittent fasting. First and foremost, your calorie intake and balanced nutrition are of paramount importance. Especially, your calorie intake should not fall below 1200.
For women with thyroid issues, “Cyclical intermittent fasting” is recommended. This means you can practice intermittent fasting according to your hormone cycles and phases. This involves adjusting fasting periods and eating habits according to changes in the menstrual cycle. For example, avoiding fasting or shortening fasting periods during menstruation. This approach aims to help balance energy levels and metabolism based on hormonal fluctuations. The goal of this approach is to enable women to fast healthily while maintaining their hormonal balance.

Why can’t some women get into ketosis?
What is ketosis? It is a metabolic state where the body starts burning fat for energy production. In this state, fatty acids in the liver are converted into ketones, which are then used as an energy source by the body. Intermittent fasting also induces ketosis by increasing fat burning in the body. During fasting, after depleting glycogen stores, the body switches to fat burning. In this process, the body can start producing ketones, thereby supporting ketosis.
However, some women may struggle to enter ketosis. How can you achieve this?
Clean up the sugar-burning system: The body needs to reduce sugar consumption and promote fat burning to enter ketosis.
Longer fasts may be needed: Some women may require longer fasting periods to enter ketosis.
Ensuring frequent transitions is important: It’s crucial to periodically transition the body from carbohydrate utilization to fat burning for metabolic flexibility.
Pay attention: Be mindful of excessive stress, toxins, and nutrient deficiencies. Excessive stress, toxins, and nutrient deficiencies can hinder or complicate the body’s ability to enter ketosis.
Intermittent fasting tips for women
Mineral/Electrolyte Balance: During prolonged intermittent fasting, the body may experience mineral and electrolyte losses, so consuming mineral supplements or electrolyte-containing beverages can be beneficial. Foods rich in magnesium, such as avocado, spinach, and almonds, as well as electrolyte drinks, can provide potassium and sodium.
For Fasts Longer Than 17 Hours: To reduce hunger during extended fasting periods, it’s helpful to consume fiber-rich foods. Fibrous vegetables (such as broccoli, cabbage, and zucchini) or foods like chia seeds are good options.
Amino Acids: You can use amino acid supplements to increase protein intake during fasting. These supplements help maintain energy levels during intermittent fasting.
Ensure Adequate Protein Intake: It’s important to consume enough protein during intermittent fasting because protein increases satiety and helps preserve muscle mass. For example, you can consume protein-rich foods like turkey breast, salmon fillet, or lentils.
Tailoring Intermittent Fasting for Women
Intermittent fasting tailored for women should be adjusted according to hormonal changes and cycles. Firstly, considering the hormonal fluctuations in different stages of women’s lives, fasting durations, dietary habits, and exercise routines should be adjusted accordingly. For example, women generally require more energy during menstruation, as they experience blood loss and hence need more energy to compensate for this loss. Additionally, due to hormonal changes, some women may experience increased feelings of hunger during menstruation. Therefore, for women adhering to an intermittent fasting eating pattern, meal timings and fasting hours should be carefully planned to meet the increased energy needs and enable fasting in a healthy manner during menstruation. This is crucial to maintain their health and positively influence their fasting experiences.
It’s worth noting that everyone can find their unique approach because each individual’s lifestyle and body are different. Going beyond absolute rules allows us to develop an approach that suits our own needs. Science provides a general understanding, aiding everyone in finding their path.
Can Intermittent Fasting Be Practiced During Menstruation?
The latest scientific research suggests that it’s beneficial for women to ease up on intermittent fasting during menstruation. Additionally, it’s recommended not to fast at all one week before the menstrual cycle. Furthermore, increasing intake of iron and B vitamins in the diet to compensate for blood loss can also be beneficial. This way, women can maintain their energy levels during menstruation.
4 Stages Women Need to Pay Attention to When Practicing Intermittent Fasting During Menstruation
- Power Phase #1: (Days 1 to 9): This phase covers the first 9 days of the menstrual cycle. During this period, it’s recommended to keep carbohydrate intake low and protein intake high, and intermittent fasting durations can be longer. The goal is for the body to use more protein as an energy source.
- Clarification Phase: (Days 10 to 15): During this period, hormonal changes and other effects on the body are more noticeable. Therefore, the term “clarification” indicates that these changes in the body become more apparent. Focusing on natural carbohydrates, leafy greens, and bitter-tasting foods, avoiding alcohol, and keeping fasting periods under 17 hours are important. The body doesn’t undergo autophagy during this phase. *Autophagy is a process where the body breaks down damaged or unnecessary cells to clean and use the intracellular components for energy production. In this case, the body doesn’t rely on autophagy for cellular renewal and may turn to other energy sources during intermittent fasting.
- Power Phase #2: (Days 16 to 19): During this period, it’s recommended to keep carbohydrate intake low and protein intake high. Fasting periods can also be extended. The aim is for the body to use more protein for energy and burn fat stores. The nutritional strategy during this period aims to support energy production and metabolism.
- No Intermittent Fasting: (From the 20th day to the start of menstruation): It’s recommended to consume higher-carbohydrate foods, especially those from natural sources. Additionally, not fasting during this period is important! The nutritional strategy during this period aims to provide the energy the body needs and maintain hormonal balance.
What Are the Benefits of Following These 4 Stages?
- Menstrual cycles become regular.
- Improvement in fertility is observed.
- Reduction in perimenopausal and menopausal symptoms.
- Improvement in metabolic markers.
- Overall improvement in weight loss.
How Can Hormonal Balance be Achieved with a Holistic Approach?
Women’s experience with intermittent fasting aims to improve hormonal balance and support metabolic health. However, it’s important to emphasize once again that women should manage their intermittent fasting experience according to their hormones. Intermittent fasting can only help improve metabolic health and enhance quality of life when approached in this manner.
Taking a holistic approach to intermittent fasting involves viewing our mental, physical, and emotional well-being as essential parts of the puzzle. By considering factors such as regular exercise, balanced nutrition, and stress management as important components of this whole, we can evaluate intermittent fasting eating patterns as supportive elements. Through this functionalapproach, hormonal balance is maintained, ultimately enhancing women’s quality of life and supporting metabolic health.
3 Important Tips for Intermittent Fasting:
- Women should make their fasting patterns more cyclical compared to men.
- For menstruating women, intermittent fasting should be reduced when hormone levels are elevated.
- A woman should avoid intermittent fasting approximately one week before her menstrual period.
