Chance, I just posted my own plateau woe-is-me story a couple days ago... and again today in the WL Support section. I'm eating 1400-1500 calories a day, working out an hour a day.
The fact you are losing inches means you are not at a total plateau. I've pretty much stopped losing inches. I mean things will decrease a tiny bit one week and go back up the next. In about 3 weeks I've lost .5 inches CUMULATIVE from 10 places I measure on my body.
I'm just starting to change up my workouts. I was rotating 3 days of 60 minutes on the TM, then 3 days of 60 minutes on the exercise bike, then a day of 60 minutes of whatever, usually Dance Dance Revolution. I've decreased the time on the machines and added in other exercises, like weights, pilates, stair climbing, etc. I have calorie cycled for two days. No plateau breakage yet though.
Unfortunately, with having a baby, you may have to adjust one of your plans, either the date you start TTC or the weight you are when you start. I understand disappointment. I mean, I'm going on a big beach trip, which I know can't be compared to having a baby, but I have been working out and eating smarter for 3 months now with this in mind... and I've lost only 4 lbs. I'm nowhere near goal so there's no reason my weight should be the way it is.
Hopefully your cleanse will help you. The only problem with them is whenever I've done them or friends have done them, they pretty much gain back EXACTLY what they lost during it. That said, I'm hoping my vacation might even make me lose weight--I'll be in a new place, eating new foods and doing new activities. Hopefully it will shock the fat right off me!
Anyways, good luck to you. I was just going to start a weight loss tips thread. I'm willing to try anything! If people have done anything and it helped them lose weight, I'll try it!
