I try to stay off the scale and only weigh myself once a week. But I have been weighing myself twice a week to check my progress. I have lost 4.5 lbs in three weeks and have been "good" everyday. This morning I weighed myself ( weigh in is normally Thursday morning) and I am 1.5 lbs heavier ! I have had a higher weight the past two weeks on my mid week weigh in, then I am lower on my Thursday weigh in. What gives???
