You step on the scale Monday morning, you went up a half pound, all of a sudden lots of things run through your mind; “Am I doing something wrong?”, “What’s going on?”.
It takes will power to push through those weeks, I found over time that not all weeks are made equally. Some times I’d gain a half pound, other weeks lose four pounds, when doing the same general diet. This is where persistence comes in. Your short term goals should not determine your commitment.
Know beyond any reasonable doubt that what you are doing is correct and keep doing it. Take monthly photos to prove to yourself that the scale is not the most important thing. This is especially true if you are doing any muscle building sort of workouts. I haven’t lost weight in the last 3 or 4 months, but there have been very drastic differences to my face.
