3 lbs in one week is awesome!! The big spectacular 10 lbs in one week are usually from folks who have a lot of weight to lose in the first place; you don't have too much to lose, so it's reasonable to expect to lose a smaller amount from week to week. Ultimately you and the bigger person will reach your goals at the same time ... and besides, when the bigger person reaches the weight you are at now, their weight loss will slow down to a lb or 2 per week too.

Being hypothyroid and NOT treated or UNDERtreated can slow the metabolism, and make it difficult to lose weight, or can make you gain weight if you have the tendency. Being low thyroid doesn't automatically mean weight gain, there are quite a few underweight hypothyroids out there.

Thyroid hormone replacement is not a diet pill. What it does is take the place of the hormone that your body isn't producing anymore. When the levels have reached normal (your doctor will be taking blood at regular intervals to check) then your metabolism will be the same as a normal person's and your weight loss efforts -- diet and exercise -- will be the same as for anybody else.

Click here for About.com's Hypothyroid pages. Especially read Thyroid Disease 101: The Starting Place and Hypothyroidism--Common Questions & Answers Post-Diagnosis. The whole site is excellent, I suggest you bookmark it to your Favorites.

Lowcarb is recommended for low thyroid, to help prevent blood sugar and insulin dips and swings. As well, you would be wise to consider avoiding sugar and refined carbohydrates for good .... as these are the foods that cause elevated cholesterol, not fats ... and hypothyroids can have problems with cholesterol.

hope this is helpful
