I was at 170 last July, I switched to keto induction, then kept carbs under 50 g total, stalled out after end of Dec. finally in March started reading up on fasting, started doing IFing mid March and then in April added extended fasting. I reached my goal weight and dropped a few extras as well by the 27th of April. Fasting was the missing link for me, even doing LCHF/keto meals. So I averaged 3.7 lbs per month, but three of those months, I lost nothing at all. I just kept calm and you know the rest 
I have always been a slow loser, so this seemed fast to me. Formerly on WW, it took me a year to lose just 30 lbs. This time it was 34lbs. in 9 months. The big drop (24 lbs.) occurred when I started fasting protocols, jsut short of two months later I was under my original goal weight number and I am staying under using IF and a few extended fasts here and there.
I had to overcome my programming of fats are bad, carbs are great, take it off slowly or it all comes back (I had pretty much proven this to myself over and over with higher carb diets, (even during my zone diet (40% carb/30p/30f periods, I’d lose and regain it quickly).
Wishing you the best in your weight loss efforts.
