The Fasting Cycle in FAS

In FAS like a girl, I map out something called the fasting cycle. And this is the tool every woman needed when we first started fasting and it looks like this. Day one through day 10 of a woman's cycle, estrogen is building, you can go into those longer fast. Then around day 16, we come out of ovulation and the hormones have dropped so we can go back into a little longer fast. But as we start to get into about day 19, progesterone’s building, and this is where we don't want to fast or be in keto.
