Yes, find it a tad bit draining though during the work week.

That's great! It actually really works wonders if you get into the habit of it rather than consciously trying to achieve it. Set achievable targets and changes will come with time. It also depend on other factors like are you still trying to stay active, eating healthier food, etc. Hope that helps :)

It needs to be done mindfully. What you consume during the IF matters(aka carbs/proteins/fiber, etc). Also matters how healthy your metabolism already is.

Not something I've ever tried. So you've been doing it and noticed no changes?!
