Rolling fast or Extended for Quick Weightloss?

Hey everyone!

I was wondering if I’d lose more if I do a 20 day extended fast and then rolling fast versus just doing a straight 30 day fast in which the refeed would be longer… will I be able to lose 10 kg during the 20 days of rolling fast after the 20 day extended fast?

My goal is to lose 20 kg by then. I’m starting at 99 kg 29 F 177 cm.

I want to be able to eat normally during September 25-26th weekend….

Thanks for any help!

I’ve done a 20 day fast before and will be taking electrolytes and black coffee!
