Wii fit plus?

Hi everyone,

I don't post often but thought of a question I wanted to ask so hope ya'll can help me out?

Does anybody only exercise with a wii fit plus?

I do about 2-3 hours a day on it and do about 1 hour running, 30 minutes rhythm boxing and about 1 hour walking with some of the other activities thrown in there. I started it properly (along with healthy eating) on the 6th August 2012 and began losing very fast. I was burning between 800 and 1100 calories a day doing it. I started at 11st 11lbs and am now already 10st 10lbs but the past few days I have hit a plateau. I have been exercising slightly less as I figured I wasn't eating enough in conjunction with too much exercise but it still hasn't budged. I am wondering if I am still doing too much burning 600-800 calories a day??

So for somebody eating 1300 calories a day and not eating the exercise calories back how many calories should I aim to burn on the wii fit?

FYI The only reason I use just the wii fit plus is because I have a little boy at home who I cannot leave to go to the gym otherwise I would and there is no one else to watch him. I am getting an air walker though so will use that also.
