I looked up the calorie burn for circuit training at some point - as this is what I do for my muscle building.
If you train in the way that you work until exhaustion in ALL exercises in the sllowed time (depending what kind of workouts you do), then you burn something like 8 calories per kilo body weight per hour. This is if you work out hard, sweat jumping from your forehead, pulse up high, and you not being able to carry any kind of conversation while working out, and with no breaks. So you'd be burning about 500 calories per session.
However, I'm assuming this is not the way you work out, given your condition. I'm assuming you're probably haft of that, which is fine for general exercise. Don't get me wrong.
My point is that circuit training, as good as it is for your body and for building some muscle, really doesn't burn a whole lot of fat, unless you REALLY put effort into it. Let's say you DO work out full blast. Then you'd lose something like 2 ounces of fat during that workout. If you only go have the burn, then one ounce.
I feel that the workouts are great for building and tonining your body, but actual fat loss is MUCH easier accomplished in calorie restriction.
It's good to see that you DO work out, though.

From October 4th 2010 to April 3rd 2012 I lost half my body weight - 80 kilos/170 lbs. Since then, I have had two cosmetic surgeries to remove excess skin. I have now quadrupled my strength, gained several kilos in muscle mass, and today I focus on building muscle, optimizing my diet, and living healthy. I am stronger, healthier, thinner, happier!
