Wii Fit

I've recently gotten the Wii Fit. I love it. I really do...it's ALOT of fun, but it's also quite motivating! The first day after working out, it said I had lost a pound....but it quickly told me that weight can fluctuate 2 pounds or so, up or down. Basically, it told me not to get too excited! The next day, I went up 2 pounds...and to be perfectly honest, I was really bummed. However, I then expected it to tell me not to worry...my weight can fluctuate. NOT!! It immediately said, oh no, let's figure out why you're gaining weight. Are you eating too late? Are you doing enough excercise? What's up with that?????
