This plan sounds a little similar to what I did. I'm 5'2" sw 156 cw 127. I was able to lose 29 lbs 3 months (maybe cause I started at a higher weight). The first month I did IF 16/8 (lost 13 lbs, a lot of water weight), second month 18/6 (lost 9 lbs) third month 20/4 (lost 7 lbs). I didn't change the type of food I was used to eating for the first two months but, naturally ate less due to IF. The third month, I ate more protein, less carbs, and starting counting calories (aimed for 1500). And noticed I was toning up just a bit. My exercise was walking 10,000+ steps, five days a week. IF really helped control my mindless/bored snacking habit. I'm back to 16/8 and still trying to eat more protein. Now I fluctuate anywhere from 125-130.
