I don't want to weigh 56lbs!!

Options
Hi all! I'm new here, so this may be my error but..
After I input all my food for the day, can anyone answer why it then says at the bottom "if you carry on eating this way you'll be 56lbs" in x amount of time? That'll pretty much mean I'm dead, which is not what I was going for. I'm still not even hitting my target of 1510 calories per day yet and it says this weight! Does it mean kg? Thanks!
