BUB4:
With Insanity you should burn around 1,000 calories per workout
This is somewhat misleading and I would recommend getting a heart rate monitor if you really want an answer to your question. A male of average weight, in pretty good shape, burns around (around, you could easily be 200 calories in either direction) 1000 calories doing a month two DVD with intensity. That said, there are lots of variables. Smaller women often come onto these boards to complain that they burn as few as 350-400 calories doing the month one work outs. Here's a few of the more important variables:
1) Sex. Men tend to burn more calories than women in the same activity. It's not universal, of course. A woman with a lot of muscle mass may burn more calories than a man of similar weight with a higher body fat percentage, but mostly men burn a few more calories than women.
2) Body weight. This is a big one. A tall man can easily weigh 250 pounds and still be "healthy". A 250 pound person is going to burn a lot more calories than a 100 pound person doing the same things. It takes more energy to move more weight.
3) Body fat percentage. Having more muscle means you burn more calories doing things. Anything. Having more muscle burns more calories sleeping, walking, working out, whatever. It's one of the reasons that strength training is good for working out, even when it doesn't burn as many calories directly.
4) Intensity. Obviously the harder you go, the more you burn.
5) Length of exercise. Month one DVDs average 30-35 minutes. Month two DVD are 45-60 minutes. Obviously you burn a lot more doing month two DVDs.
From your picture I can see that you are female and not terribly heavy (though if you're tall it could make you heavier than you look in a picture). Based on what my wife burns in a workout, and what I've seen other women post here, I'd not be surprised if you were closer to 500 calories for a month one workout and maybe 750 for a month two. I could be totally wrong though, better to get a heart rate monitor.
