New to IF | What to expect

I started IF a couple of weeks ago. Monday, Wednesday and Friday = OMAD / 24 hour fast from previous evening meal @ 5-6pm. Other days = 2x meals in 20/4 window. These are lunch (1-2pm) and dinner (5-6pm). My meals are fairly sensible, but not extreme dieting - e.g. evening meals are around 600 to 800 calories with large quantities of vegetables. Lunches are similar. I'm 6'1" male and I estimate my weight to have been 16 stone / 224 lbs (UK) at the start of the diet. I've not weighed myself because I've previously got obsessed and disheartened by constanty weighing myself during my previous weight loss plans. I think my ideal weight would be around 12 stone / 168 lbs. I'm not finding the 24 hour fasts too difficult, and I'm eating fairly sensibly, but I'm fairly inactive - busy IT worker with young family which doesn't allow time for gym. It's only been two weeks, but I can already see a difference in terms of how bloated I look and the way my clothes fit. Is losing two pounds per week a realistic goal? If so, that would suggest six months of IF to get to my target weight? Am I being overoptimistic? Thanks.
