Running and dieting please help!?

Okay so two weeks ago I started the b vitamin shot and taking phentermine to lose weight, the doctor also wanted me to go on a low carb for the 1st month. He barely let me join the program because I am technically not overweight. I am 5'4 and weighed 137, but I had absolutly no energy. So I began running, the pills help me to have the energy to do so and I run or jog about 4-5 miles 5 days a week. Well today I had my 2 week check up and had only lost 3-4 pounds. The nurse said that I should have dropped at least 10 pounds. I said that it was because I am gaining muscle, and she said that I need to do the no carb and not jog for the next couple weeks. I want to keep jogging, and don't want to go no carb. What can I do to maximize wieght loss so I can stay on the program? I eat healthy, should I start jogging twice a day. I am sure that if I don't lose at least 8 pounds in the next 2 weeks they may not let me continue.

Did you notice that in your question you did not mention at all the "problem" you are trying to solve?
If you lose 8 pounds, your body mass index (BMI) will be only 22.1, which is a little more than the minimum healthy measurement for a woman (see the charts on my reference website below).

If you run, say, 15 miles a week, that will be 1500 calories. If you keep your calorie intake steady, the weight will fall off all by itself.

I am shocked that a doctor could give you medication to help you lose weight, when there is clearly no medical need for you to do so and even more shocked that a nurse could advise you to stop taking exercise, the benefits of which far outweigh efforts to lose weight that a. you don't need to lose and b. you will lose anyway if you keep jogging. I would strongly advise you to get some independent advice from a different doctor.

Your weight loss is normal.

I am on low carb, low fat, high fibre, high protein and a hour brisk walk 5 times a week, and I have lost 31lbs and gain better health. I am now maintaining my 108lbs for more than a year.

I am not on any programme or treatment and yet I am able to lose all these weight and maintain.

Details such as meals, recipes, walking as an exercise and to shape the body etc etc, are in my blog
