Having lost a similar amount of weight in 3 months by switching to keto (pretty much the opposite diet from OP, but similar IF schedule) I'm not surprised. If I'm being totally honest I attribute most of the gains in weight and mental clarity to reduced drinking, particularly before bed. Also apparently the occasional basket of french fries / onion rings was really adding up. In my case I dropped from 102 kg -> 79kg. I'm tall and naturally very slender, but I'd gained a lot of weight while working at Amazon. I also attribute the change to quitting a high-stress job, thereby removing a lot of "stress eating / drinking" in addition to using a rigid rule (NO CARBS) to avoid most of the fried garbage I'd binge on. I'm not that surprised - I was eating and drinking like it was my job to gain weight and keep it on, then I stopped.
