I agree that your weight can fluctuate and and also that the exercise will build muscle that is heavier so sometimes it's better to see how you are losing inches off waist, hips etc as a guide. Are your clothes looser? But don't forget it's important to make sure that not only are you limiting your calorie intake but ensure that they are not empty calories that require a disproportionate amount of enengy to burn off compared to their nutrien value.
