2 verifications about fasting fasting ×
“Fasting is not healthy for women who have high cortisol levels.”
While fasting does acutely raise cortisol and women show sex-specific changes in cortisol rhythm, the peer-reviewed evidence does not establish that fasting is clinically harmful for women with pre-existing high cortisol levels. The claim conflates a measurable hormonal response with demonstrated health harm—a logical leap unsupported by the highest-quality studies available. Sources making the stronger causal claim are predominantly wellness blogs and commercial health platforms, not clinical research on this specific population.
“Fasting is not recommended for women over the age of 50.”
This claim is false. No major health organization or clinical guideline issues a blanket recommendation against fasting for all women over 50. While some medical literature cautions against fasting in "advanced age" or the "elderly," these terms are not defined as starting at 50. Multiple authoritative sources — including the Cleveland Clinic, peer-reviewed PMC studies, and Harvard Health — indicate intermittent fasting can be safe and potentially beneficial for postmenopausal women when approached with medical guidance and individualized assessment.
