Hiya, a lot of people have been saying that they feel heavy and don't feel like they have lost any weight, yet they then get the surprise with a loss.
I know its easier said than done, but try and not fret. Sometimes it can our bodies up to a week after being "good" for it to show on the scales. Some people get a bigger loss in their 2nd week.
Just have faith in the plan, make sure you're eating the SW way and keep going.
Good luck x
