For women, it is preferable to prioritize a short morning fast (stopping eating early in the evening and eating breakfast before 8 a.m.) rather than intermittent fasting that delays the first meal, in order to stabilize hunger hormones and cortisol.

Stacy Sims highlights a real physiological difference: women exhibit increased sensitivity to cortisol in the morning, which can influence hunger regulation. The idea that prolonged fasting may exacerbate metabolic stress in some women is supported by observational studies suggesting that the response to stress and caloric restriction differs by sex (Journal of Applied Physiology). However, the claim that eating before 8 a.m. is systematically superior lacks evidence from robust randomized clinical trials (RCTs) in a large female population. The 'front-loading' approach (concentrating calories at the start of the day) is corroborated by research on chrononutrition (meta-analysis in Obesity Reviews), showing benefits for glycemic control. It is important to note, however, that autophagy often requires a fasting duration longer than 14 hours, which makes the claim about achieving 'autophagy benefits' with this protocol somewhat optimistic. In short, the approach is consistent with principles of hormonal health, although results may vary according to individual metabolic profiles.
