I am a 29yr/F, 5' 2" and have been in 180s for almost 5 years now. I am fairly active, do some form of intentional exercise most days of the week. I was not eating terribly unhealthy but White rice was biggest vice and I can easily overdo it. I used to keep a food log on LiveStrong but was not very consistent.
Since 11/23/09 I have been using the BodyBugg (the device Biggest Loser Contestants use to keep track of calories burned). BodyBugg comes with a food logging program to keep track of calories ingested, and with the bodybugg recording calories burned to aim for a deficit. Here are current stats:
Starting Weight: 182 lb @11/23/09
Current Weight: 161.2 @1/31/10
Target Calorie Intake: 1250
Target Calorie Burn: 2250
Target Weight Loss: 2lb/Wk
It been 10 weeks since I started and I have been lossing around 2lb/wk until two weeks ago where it has been about 1.2lb/wk. For exercise I run on the treadmill, just started doing some weights (the machines), take a Karate class and do something or the other for atleast 1.5 upto 2.5 hrs/day.
Is this good? average nutrition breakdown has been 62% carb, 24% protein, 14% fat (got this off of food log

Am I doing things right? Just this week I started HIIT (not in the true sense still getting used to it), the one FitoverForty suggests:
10 min warmup @4mph
Stretching
1 min - 3 X @6.6mph
2 min - 3 X @5mph
5 min @ 3.5mph
20 min @5mph
10 min cool down @3.5mph
Stretching
Weights upper body and lower body alternate days. Sunday no weights.
Does all this look right? I am absolutely terrified of a plateau and being stuck in the 160s and worse still gain back what I have lost. Healthy weight range for me is 101-136, I would like to maintain at atleast 125-130. Will I ever get there with the way things are going. People keep complimenting me on how good I look and it is overwhelming. What if I gain it all back. And then they say I look good, compared to what, 2 months ago. Still for a person who has never seen me, I am still an overweight obese female. Sorry for the long post, but I just want someone to listen and understand. You all are such a great support.
