If you are going to weigh yourself, then it should be done the first thing in the morning after you have gone to the bathroom and before you put anything in your mouth. Also, don’t get into the habit of weighing yourself every morning, because you will be setting yourself up for failure. What you need to do is weigh yourself every 10 to 14 days. If you start to gain weight or you can feel that fluff coming on, then you know you need to buckle down and start looking at your food and exercise regimen with a little more attention.
