Question has been rolling around in my head recently. How long do you really need to fast (obstain from all caloric intake that can produce a blood sugar response) when doing IF to reap any real benefits (eating at maintenance for the feeding window) for insulin sensitivity, leptin sensitivity, hormonal cascade/balance etc...? Lots of folks 'round these parts do 16/8 to 20/4 fasting/feeding windows. Tagging @kennycro@@aol.com and @mprevost as well.
