Yes, fasting can affect your menstrual cycle, particularly if fasting is prolonged.
How Fasting Impacts Menstrual Cycles
The length and frequency of your fasting can play a role in how it impacts your menstrual cycle. Here’s a breakdown of how fasting can influence your period:
- Prolonged Fasting: According to research, a fasting window of more than 14 hours could affect a woman's period cycle. This means that consistent, lengthy fasting could potentially lead to cycle irregularities.
- Hormonal Imbalance: Fasting can impact hormone levels, including those related to the menstrual cycle. This is because the body may perceive the restricted eating as a stressor, which can affect the hormones that regulate menstruation.
- Energy Deficit: Fasting can result in an energy deficit, which can also affect the regularity of your period. The body needs adequate energy to maintain its reproductive functions, and severe restrictions may lead to disruptions.
Considerations When Fasting
When considering intermittent fasting, especially if you're a woman, it's essential to pay attention to how your body responds:
- Monitor Your Cycle: Keep track of any changes in your period, such as irregularity or changes in flow, when fasting.
- Adjust Fasting Windows: If you notice negative changes, consider shortening your fasting window.
- Consult a Professional: Before starting any fasting regimen, it’s advisable to consult with a healthcare professional or a registered dietitian, especially if you have a history of hormonal imbalances or menstrual irregularities.
| Aspect | Impact |

In conclusion, it's crucial to be mindful of the length of your fasting periods, particularly as a woman, as prolonged fasting can impact your period.
