It's not a magical license to eat as much as you want! It's still very easy to eat a surplus of calories during the day even if you're doing intermittent fasting.

I currently eat during an 8-9 hour window (12pm-9pm) but mostly because it's much easier for me to stay satiated over the whole day when eating like this and keep my total calories down.

Use something like MyFitnessPal to track your calories, set a calorie goal for each day (below your maintenance level) and you will be amazed how easy it is to lose weight (or gain weight if that's your goal).

Also, there's nothing wrong with skipping breakfast.
