Fasting can be a powerful metabolic health tool, but extreme schedules can stress the female nervous system. In perimenopause, your body is already under hormonal stress—adding the stress of long fasts can backfire.
The Goldilocks Window
Most experts recommend a 12 to 14-hour fasting window for women over 40. This provides the metabolic benefits of autophagy without triggering a significant cortisol response.
Your Fasting Plan
- Start with a simple 12:12 window (8 PM to 8 AM).
- Break your fast with at least 30g of protein.
- Avoid fasting during the week before your period.
