why am i not losing hardly any weight?

[roxstar007]

I am 36, 5'4, and weigh 192lbs and don't have any thyroid issues. I have started dieting and exercise since April 8, 2012. I am working out doing Jillian Michaels everday for about 1 hour since I began. I work as a Nurse so when at work I am constantly walking and taking stairs. When I went in the first week to weigh in at Jenny Craig i lost 1/2lb. Second week lost nothing. Third week lost 2lbs. I did Jenny Craig 9 years ago and had no issues losing weight in fact I was losing approx 2lbs per week and lost 40lb in 6months. So I can't help but feel discouraged because I don't know what I'm doing wrong, I follow the menu planned out for me during the week by Jenny Craig, and exercise religiously, what do you think is going on, why am i not losing  as much as i would like?

Thank you so much for your advice, and knowledge, I guess I will just need to be patient and stop focusing on the numbers, but rather wait until I start to see and feel myself losing inches and feeling healthier and more fit.

Sometimes your body just needs to get used to the new weight and metabolism. Remember, if you diet, at one point your body just "panics" and completely switches its metabolism over to "keep everything", since it fears that it might starve. This can take a few weeks, or a few months, depending on how dramatic the loss was and how your genes are. As long as your weight does not go up again, this is completely normal and healthy. Give your body time to adjust, so it gets comfortable and understands that it will not starve, and your weight will drop further again.
Additionally, the first weight you usually loose it water, then some muscles (the body doesn't want to loose the fat reserves, so it keeps it as long as possible). The next step is the fatty tissue diminishes, but the muscle gains, and muscle is heavier than fat. Your weight might not drop during that time, but your body shape will get slimmer, tighter, and the fat around the organs vanishes. As soon as the muscle build up and metabolism outruns the fat loss, the body weight drops again.
