Fasting Q&A with Dr Jason Fung: Fasting and Insomnia, Autophagy Research, HDL/Trigs Ratio, Perimenopausal Weight Gain, Weight-Loss Stalls, and More.
Episode #202 In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community: I’m curious if TFM intends or would consider a ‘fasting-mimicking protocol’ to be published for its members, possibly a TFM Quick Guide? [01:22] When I fast I find that I have trouble falling and staying asleep. Is it the hunger increasing my cortisol or the effect of ketones? What are your thoughts on valerian or kava tea to help with fasting insomnia? [02:54] What’s the latest research on autophagy? [05:12] What does research say about the relationship between the HDL/Triglycerides ratio and high coronary calcium scores? And, in general, what does the scientific literature say about potential interactions between statins and fasting regimens? [07:00] There is a hormonal cascade where our sex hormones are made from cholesterol. We know from member stories that female hormones become balanced on alternate day fasting regimen. In those success cases, how does alternate-day fasting affect the hormonal cascade so that it starts working properly again? [12:59] I was recently reading research that suggests that moderate weight gain during menopause, particularly in lean women, may offer a degree of protection against cardiovascular disease, due to the increased production of adipose-tissue-derived estrogen, which can partially compensate for the decline in ovarian estrogen levels following menopause. What are your thoughts on this? [15:27] Why might weight loss stall during a multi-day fast, even when following an extended-fasting protocol with proper hydration, electrolytes, and exercise? What factors could influence the rate of weight loss, and how can one determine if adjustments are needed? [19:02] Is there a problem with lowering metabolic rate during fasting? Do I need to worry about this? [21:13] The RR interval typically refers to the time between consecutive R waves in an electrocardiogram (ECG/EKG) and is a fundamental measurement in heart rate variability (HRV). Has the RR interval been studied in diagnosing gastroparesis, specifically for diabetes?
