Hi there!
The idea is that you should stick to plan 100%. I know many of the people on here have a "treat" meal after weigh in, some have flexible syns at the weekend.
If I were you, I would start doing it 100%, as when you stand on the scales, there will always be that element of thought "how much would I have lost if I had stuck to the plan".
Im a goody two shoes really...I would be too afraid to have a treat meal, as I gain weight too quickly.
Its your decision at the end of the day Hun.
