If you are following the plan as given to you, then you really can't do it wrong! What you are doing "wrong" is weighing in between official weigh in days and expecting to see consistent declines!! Weight loss is not a daily incremental decline but rather a downward trend over time.
The scale can vary up to 4-6 pounds up or down in one day!! Yes that's right, weight goes up and down all day long. The purpose of weekly weigh-ins (preferably at the same time of day and wearing the same thing) is to see a trend week after week, not day after day.
Stay dedicated to the plan and stay off the scale OR if you want to weigh, be sure you both understand the expected ups and downs and can handle seeing it in real numbers without getting discouraged or worrying! (BTW - did you know worry and stress can make your weight go up?)
Keep on keeping on... On Plan that is!!!!!
