Intermittent fasting (IF) has gained immense popularity as a dietary approach for weight loss and overall health improvement. It involves alternating periods of eating and fasting, which can range from hours to days. While many people have found success with IF, it's crucial to understand its specific effects on women's hormones. Recent research conducted by The University of Illinois Chicago sheds light on a significant concern: the potential impact of intermittent fasting on DHEA levels in women.
The Basics of Intermittent Fasting

Intermittent fasting encompasses various methods, the most common being:
- 16/8 Method: Fasting for 16 hours and eating during an 8-hour window.
- 5:2 Diet: Eating normally for five days and restricting calorie intake to about 500-600 calories on two non-consecutive days.
- Eat-Stop-Eat: Fasting for 24 hours once or twice a week.
This approach has been linked to numerous benefits, including weight loss, improved metabolic health, and enhanced brain function. However, its impact on hormonal balance, particularly in women, requires careful consideration.
The Role of Hormones in Women's Health

Hormones play a pivotal role in regulating various bodily functions, including metabolism, reproduction, mood, and overall health. For women, maintaining hormonal balance is especially crucial due to the complex interplay of hormones such as estrogen, progesterone, and DHEA (dehydroepiandrosterone).
DHEA is a hormone produced by the adrenal glands, and it serves as a precursor to both male and female sex hormones (androgens and estrogens). It is involved in various physiological processes, including immune function, energy production, and stress response. A decline in DHEA levels can affect a woman's overall health and well-being.

Researchers at The University of Illinois Chicago conducted a study to explore the effects of intermittent fasting on women's hormones, with a particular focus on DHEA levels. The study involved a group of women who followed a specific intermittent fasting regimen over a set period.
Key Findings:
- Weight Loss Benefits: Participants experienced significant weight loss, improved insulin sensitivity, and reduced markers of inflammation. These benefits are consistent with previous research highlighting the positive effects of intermittent fasting on metabolic health.
- Decrease in DHEA Levels: Despite these benefits, the study revealed a concerning drop in DHEA levels among the participants. DHEA is crucial for maintaining hormonal balance, and a decline in its levels can have various implications, including reduced energy, decreased libido, and potential impacts on bone density and immune function.
Implications of Reduced DHEA Levels
The decrease in DHEA levels observed in the study raises several concerns:
- Energy Levels: DHEA is involved in the production of energy. Lower levels can lead to feelings of fatigue and decreased stamina.
- Immune Function: DHEA supports the immune system. Reduced levels might make women more susceptible to infections and illnesses.
- Bone Health: DHEA plays a role in bone density. A decline in its levels could increase the risk of osteoporosis, particularly in postmenopausal women.
- Mood and Mental Health: DHEA is linked to mood regulation. Lower levels might contribute to mood swings, anxiety, and depression.
Balancing the Benefits and Risks
While intermittent fasting offers numerous health benefits, it is essential for women to be aware of its potential impact on hormonal balance. Here are some strategies to mitigate the risks:
- Consult with a Healthcare Professional: Before starting any fasting regimen, women should consult with a healthcare provider, especially if they have underlying health conditions or are on medication.
- Monitor Hormonal Levels: Regular monitoring of hormone levels, including DHEA, can help detect any imbalances early on.
- Adjust Fasting Protocols: Women may need to modify their fasting schedules to ensure they do not experience adverse hormonal effects. Shorter fasting periods or less frequent fasting might be more suitable.
- Focus on Nutrition: During eating windows, women should prioritize nutrient-dense foods to support overall health and hormonal balance.
- Consider Supplements: In some cases, supplements such as DHEA may be recommended by a healthcare provider to maintain optimal hormone levels.
Intermittent fasting can be an effective strategy for weight loss and overall health improvement. However, women must be mindful of its potential impact on hormonal balance, particularly DHEA levels. The University of Illinois Chicago study highlights the need for personalized approaches to fasting and underscores the importance of monitoring and maintaining hormonal health. By understanding and addressing these potential issues, women can reap the benefits of intermittent fasting while safeguarding their hormonal balance and overall well-being.
