How many calories for meal when doing rolling 48s?

Hi, so I’ve been doing OMAD for the last 6 months or so and have really loved it but have now switched over to rolling 48s. How much is everyone eating for their one meal? Because my BMR is around 1350 and my TDEE is around 2200. Is 1500 enough or too little or too much when fasting for WL? Because that is where most of my meals during my rolling 48s are falling around and I was wondering how much everyone else is having. For context I’m 5’2, female. Thank you!
