Why is it better to loose inches and not weight?

Lost inches are a more objective way of measuring a movement towards a fitter body. A looser fitting pair of pants is a sure-fire way to tell one is losing weight. Weight loss can vary greatly with water weight (a function of salt consumption, medicine intake, caffeine intake), the amount of food consumed recently, the amount of waste carried in the bowels, the clothes being worn, the accuracy of the scale, and so on.
