My husband has done IF in the past with good results, but I definitely want to pop in and mention that women can be more sensitive to starvation so IF should be used with caution. Also if you have thyroid or adrenal issues it is probably not a good idea.

I know several women without any thyroid or adrenal issues that have seen great results though!
