Hi! First of all, the workouts sound GREAT! Secondly, I must tell you that I am NOT a "dieter", a "calorie-counter", or any of those things. So, you might not like this, but I saw your post just as I was about to get off-line and I didn't want to let it go.
Since I *don't* diet myself, I'm not going to try to figure out how many calories someone else eats/ate. BUT, you might not be eating enough. THAT'S A HECK OF A LOT OF CALORIES YOU'RE EXPENDING! I didn't calculate how many weeks of workouts you laid out, but you might have sent yourself into "starvation mode". Maybe right *after* interval training, drink a glass of milk (I don't like milk, so I add chocolate!) or some other low fat or lean protein snack.
That's just a quick thought. I really want to help! Don't give up!
BTW, in this post earlier this morning, I gave a "long-winded" explanation of how I lost 70 lbs: http://www.medhelp.org/posts/Weight-Loss--Dieting/b12-shots/show/946561
