Dr. Stacy Sims is making vociferous arguments that Zone 2 is not really necessary for women because their mitochondrial system is generally healthier and more robust than in men to begin with. Further, she says Zone 2 is detrimental to perimenopausal and menopausal women because it spikes cortisol at a time when they most need to keep that down. According to her, most of the research on Zone 2 is focused on men and, if including women at all, pre-menopausal women. Is there any merit to this? Should I stop telling all my older women friends to do Zone 2 and focus on sprinting instead? Can you either interview her or clear the air for us on this? Whether she's right or wrong, there isn't much on the podcast about menopause or perimenopause outside of HRT, and that seems like a potential huge oversight, especially considering the aging population.
Can this possibly be true? Do you believe the news it was ALL over the news yesterday. I currently fast for 16 hours a day and get as much protein in as possible during my 8 hours of eating and eat as healthy as I can during that time. How can that cause me Cardiovascular disease???
