metabolic shift caused by intermittent fasting, particularly the transition from glucose to fat metabolism, may interfere with the normal functioning of hair follicle stem cells.
Although the researchers observed this effect in mice, they caution that the impact on human hair growth may be less pronounced due to differences in metabolic rates and hair growth patterns. The researchers also emphasize the broader benefits of intermittent fasting, including its positive effects on metabolic health and stress resistance in stem cells, which could outweigh the slower hair regeneration observed in the study.
Ultimately, while intermittent fasting is associated with many health benefits, this study highlights the importance of considering potential unintended effects, especially for those who may be concerned about hair loss or slower hair growth.
