I need to Vent

Okay. I joined a 12 week weight loss class at Spin last week. It's a low GI diet, called Transitions Lifestyle. http://www.transitionslifestyle.com You know me, I'll try anything, ONCE. ;-)

Anyways, they started us off with 7 days of 'detox'. That meant eating only veggies and 3 servings of fruit a day (and water). No caffeine, no sugar substitutes, no crap. So I did it. Today is the last day. I admit that I did have one cup of coffee each day because I don't need the headache. The idea is to 'clean out your system'. They went through all the reasons to do it and what it means to your body. OK fine, I get it. Monday night after class they weighed us and took our measurements. That was a rude awakening for me. I know
I'm fat, but Holy Cow! My measurements are just about straight up and down! I'm a box! Anyways....

So, as I said they did this after Spin, and the discussion, so that was around 9 PM. AFTER I ate dinner, AFTER I drank 2 24oz. Bottles of water during 2 Spin classes. So the weight that they recorded was a bit more than I normally see when I weigh myself in the morning, about 2.5 lbs. more. I expected that....

So here I am into the 7th day of detox. I weighed myself this morning, just because I was curious. I've been working so hard at this and really staying with it. And guess what? I weight about 2.5 lbs. less than I did last Monday night. So that means I weigh EXACTLY THE SAME!
I've eaten nothing but friggin' veggies for a friggin' week and nothing has changed!!!!!
How can this be? My metabolism must be dead, I mean really dead!

I am really depressed over this. I know they said it's inches, not the number on the scale, but I don't feel any different! I've been emailing back and forth with one of the other ladies that's doing this, and she said she feels 'less bloated'. I didn't feel bloated to begin with, I just feel fat. And I STILL feel fat. My clothes don't fit any different, my rings are still tight on my fingers, NOTHING has changed. I'm ready to jump out a window....

Thanks for listening, and letting me vent.

Edited to Add: I joined an exercise place back in 07 (see this post). I do 5 classes a week, faithfully except for when I had surgery last October. Classes I take:
Mondays - Core Sculpt 30 minutes, and RIDE & CURL, 30 min spin & 30 upper body.

Wednesdays - BURN BODY BURN, 55 min non-stop body sculpting
and JUST RIDE, 45 min spin in various energy zones.

Saturdays TOTAL WEEKEND RIDE, 45min spin & 25 min total body (longer class).

This month I added every other Tuesday - CYCLEBOX~Crunch 15 min spin / 35 min kickboxing & 10 min abs

During detox week though, they told us NOT to exercise. So I haven't been since last Monday night.
