Theoretically it takes a 3500 calorie deficit to lose 1 lb (i.e. cutting calories and/or exercise).
Do you know how many calories on average you were eating before? If we assume you were around 2000, then cutting down to 1530 calories per day would give you 3290 deficit per week, which is where your exercise would come in.
My suggestion, stick to the 1530 calories even on days that you do light workouts. Keep your diet consistent and try to minimize the days where your calories spike higher, this will give you good habits to make a lifestyle change, vs just trying to lose weight.
In the past, for me, having more for breakfast and lunch has been more beneficial for me (i.e. protein heavy breakfast and lunch) this keeps me sustained for the majority of the day with a few light snacks in between and then I can make something light for dinner. I use the fitness pal app on my phone also, remember that it is a great guide to keeping you on track and honest about your calorie intake but it isn't exact. Keep your portions under control and as accurate as you can.
Good luck! I hope this helps.
