.I like to call these phantom pounds, so what do you do when you get on the scale and have gained or maintain after a perfect week?
From personal experience if in two-three weeks I'm still not losing I journal everything and figure out that maybe I'm not as on plan as I thought. On the other hand, if I am completely on plan, I lose more lbs then normal in the following weeks which more then makes up for one or even two weeks of stalling.
So, what do you do? Stay on plan? Change it up? How long do you wait?

I weigh daily and I know when I gain two pounds over night it is NOT two pounds of fat. Nope, never! I KNOW this because a pound a fat is equal to 3500 calories and to gain two pounds of FAT over night would mean I'd have had to consume an extra 7000 calories in one day.
So then the rational part of my brain kicks in and realizes that it's water weight and if I've been working really hard that week it's water weight that is repairing my muscles.
