Once a week. same day. As soon as you wake up in the morning go to the bathroom and then weigh yourself. DO NOT weigh yourself everyday. Do not worry, weight will keep coming off and you will hit your goal. Follow the rules and understand, it is a tool not a solution. Most important, stay active and do weights to keep the muscles. Otherwise, you will lose fat and muscles at the same time. I work out 5 days a week, live 50 miles away from my mouse. and work 9 hours a day and yet I find time to workout and do cardio.
