Every once in a while i check my weight, when i do i check it the next day too.... i think my body is weird i lose 5-10 lbs in one day .. when i check it the 1st day i weigh 145 and the next like 140 or like one day 145 and the next 135... it is so weird, how is this possible? i use different scales too- so i am very sure that it is not the scales:) also i am 15 years old....

Water weight.

its the scales. that is possible but extremely unhealthy and you would die within a week from exhaustion, starvation, and dehydration. you must be "gaining" this weight back after you "lose" it right?

you must really drop a load, you should take pictures, but actually, check your weight in the morning before you eat, drink, or do anything else, and do it w/ any clothes, besides that I don't know

The amount of food in your body determines how heavy you will be. Just weigh yourself right when you get up, before you eat, in order to get a more accurate number.

yeah, but mostly water weight and food weight, do you drink alot of water, and it also depends on what you are wearing.

eat the right food for your blood type and according to calories and follow some weight lose tips and you will be able to lose weight, visit this site for complete diet chart and weight lose tips

different scales, also weighing yourself right after you eat/drink then again after you urinate or defecate... or if you chop off a limb

OMG!!!that happens 2 me too!!!
like one day i was 85,than 90,than 75?
its weird:)
its water weight though:)

You use different scales. That's why...

It's not possible in any way to lose that much weight in one day unless you have some sort of surgery.

Law of Attraction.

Its the scales. Stick with one scale. Not a million.

that's weird but u probably have a high metabolism
