just using your jean size isn't really going to give you a good representation of how you are doing
Any good dietitian or weight loss 'expert' will tell you that weighing yourself isn't always the best and to take in to consideration clothes and measurements, some weeks you will lose no weight but that isn't to say that you haven't lost. A lot of people on diets focus on the scales and become disheartened (then stop) when they're not shifting but not realising that they may have lost 2-3inches off their body, especially those who do exercise.
Some experts tell you not to weigh at all (or maybe once a month) because you just know when you are at the right weight, and a lot say to ignore BMI as it is a ridiculous measurement.
