Yeah that will work wonders to lose weight. The advantage doing the fasting dry is you feel warmer and are less hungry.
Two things you should be careful of: 1) ensure during your feeding windows that you are getting enough nutrients, only eat high quality, whole food, and you might want to supplement specifically minerals like magnesium/calcium/sodium. Potassium is hard to supplement, so just eat meat, potatoes, leafy greens and avocados as your diet allows. 2) don’t force yourself to stick to a strict regime - you might feel like you need to make your eating windows longer for example a day or two. Try and stay a bit flexible and sensitive to how you’re feeling. It also might be more difficult for a while if you’ve never fasted before.
Good luck, hope it goes well!
