Lithium scales? are they accurate? -

i am on this weight loss program and i have bought a Taylor Lithium Scale (digital) that i have in my bathroom. my problem is the scale is not accurate. it changed reading in a difference of 2.5 pounds in a few minutes. example: i got on the scale and it said _92.5, then i got off of it waited about 30 seconds, got on it again and it read the same thing, so i got off of it and waited another 30 seconds got on again and it said _91, so i got off and waited again and it repeated the same thing, so i got off and waited and got on again and it said _90, so again i got off waited and got on and it repeated itself again and i tested it on more time and it went back to _91.5. which reading is accurate? how do i know which one is right? what can i do the get the same reading? does anyone else have this problem and what did you do?

just don t weigh yourself. eat healthy, excercise...you ll know you re losing weight when you FEEL different.
