The OP description matches my experience fairly accurately - I lost ~9 kg in 4 months (yay!) using essentially the same routine. Prior to this, I've done IF (18:6) for 18 months without any visible weight loss simply because I was ingesting the same amount of food just in a shorter interval. It really started working when, in addition to the IF (which I kept for other benefits), I started restricting my calorie intake - not counting calories, but simply setting a reasonable portion size and sticking to it, only reducing slightly after 7-10 days of lack of progress. Other things that helped me greatly: -don't sit at the eating table while being (really) hungry! I have a snack (fresh fruits, vegetables, various nuts) 1 hour before the actual meal, such that when sat at the table I am in control, and can stop eating easily. -prepare your food, place it on a plate, take a picture and send it to a friend before starting to eat! I used to start eating as I was preparing the food, and it becomes hard to keep track of how much you ingested. Plus, when you take a picture to send it to someone else, you look at it with different eyes, and it jumps out at you: Hey,this is a lot of food!)
