Thank you MarathonMan. That was my sentiment too.
It does not take a master's degree to realize that this is an invitation for disaster. You are not losing weight. You are only losing water. Sorry to be blunt, but you can easily dial in a ride to the ER by doing this.
The correct way is to always weight yourself at the same time at the same place, first thing after waking up in the morning and before you consume any food or water. Anything short of that, you are fooling yourself.
