Your enemy, the scale. The lying metal, glass and electronic serpent.
Do you know why? Because it seldom can tell the whole truth. Yes, it tells us how much we weigh, but it doesn't know our muscle mass, it doesn't know if our measurements changed.
For example, I weighed the same weight for three years, I don't look the same though - it was a very different looking weight at the end of the three years than at the start.
So, don't just use a scale to document your journey, take all your measurements (chest, waist, hips, thighs, biceps). Take a picture every week. You'll be amazed at some of the changes you'll see - even when there are times the scale doesn't seem to move.
You can do this.
