Intermittent fasting often has a different effect on women due to hormonal factors.
Longer fasting periods (> 1 day) in particular can lead to a hormone imbalance, as more stress hormones are formed. This is especially true if the body is not yet used to fasting.
If you, as a woman, notice symptoms such as hair loss, mood swings, sleep problems or irregularities in your cycle, reduce the intensity of the fasting and consult your gynecologist.
