Same experience here. The leangains IF Two Meals Pre-Workout plan fits my lifestyle perfectly. I typically have a long lunch break, a late afternoon coffee break, train after work (9-5 job) and eat big after training, so IF fits it to a T. I still eat the same stuff I used to, but I don't have to stress over too many smaller meals. I also find that having a big dinner and skipping breakfast for some reason gives me plenty of energy in the morning and I'm slightly more productive at work then.
In the first two weeks I lost some quick water weight and went from almost 86kg in the morning to 82.5 at one point. It eventually went up as I started to get hydrated properly and ate more. Atm I'm at 84.5kg in the mornings, after a month of IF. This morning, as I put on an old belt, I noticed that it's the same notch I used when I was 71kg prior to lifting.
The weight loss around the gut has improved my deadlift leverage in conventional stance too.
