I don't think that's how that works. It's all calorie in calorie out, and once acclimated to a new routine most people within normal activity levels settle in burning around 2000kcal a day, that's sedentary and active people. Metabolism has way less impact than most people think and outside of heavy labor or semipro athlete you're probably settling in around that 2000kcal maintenance level. Unless you were doing strenuous labor or working out daily your maintenance level probably didn't change that much.
