Easy way to lose weight

I weighed myself this morning and I had lost 6 pounds since 2 days ago. Now I haven't had surgery or a stomach bug in the interim. So I scoot the scale to the left a little and now I have lost 4 pounds. Still seems odd. Do I move the scale again and risk gaining more weight back. Now mind you this is a scale usually gives same weight 3 times in a row. It does not lie. I scoot it again , now 1 pound. I am afraid to keep moving it. So I pick it up and look on bottom. There is some cat hair, okay a lot of cat hair is stuck to the bottom. I clean off and start to set it down. And there on the floor is a ring from the lid of a milk jug. So see there is the secret -Place a milk jug ring under the scale (still the cats' fault). Weighed myself again and I weigh the same as 2 days ago. See this scale doesn't lie.
