Hello, I am new to this forum. I was just prescribed phentermine, and was curisous about a few things. I am 5ft 2in and weight 187lbs, I am about 45lbs overweight, I went to the Doctor to seek help losing weight. My appetite has been uncontrolable...craving carbs all the time. I manage to eat healthy all day, but in the evening I succum to sweets and carbs. I workout doing water arobics 3 times a week, The weight just will not budge. It is starting to effect my health--knee pain, acid reflux, fatigue, sleep apnea to name a few. I noticed when reading the side effects portion of my prescription that alot of the health problems I am trying to avoid by losing weight-- such as heart desease and highblood pessure etc. are listed as side effects of this medication...I was just wanting to get someone elses oppinoin on the effectiveness of phentermines. I know I need help with losing weight , I just don't want to replace the health risk of being obese with the health risk associated with this medication.

Hi Sherrie,

Phentermine is an FDA approved medication for weight loss but it is strong and not everyone tolerates it well. Most people don't take it for more than 4-6 weeks, and it is approved only for 3 months. You should direct your medication questions to your pharmacist or physician. You can also search here

As for you not losing weight, the thing about it is that to lose you must burn fewer calories than you consume no matter how much exercise you do. Even if you run a marathon every day, or even with phentermine, you will not lose weight if you consume more calories than you burn. So if you're not losing then you are consuming more calories than you burn, even if you think you're not. In fact, research shows that people can under estimate their calorie intake by as much as 40% to 50%. I know that it can be frustrating, but there's plenty that can be done about it.

Depending on how serious you want to get, I suggest you do any or all of the following:
1. Continue with exercise or start if you're not. Build up to 3-4 days a week of cardio for 30 minutes, and 2-3 days of resistance exercise. Exercise builds muscles and can raise metabolic rate, it burns calories, it will help you get fit and strong, and it's the best predictor of keeping your weight off.

2. For the next week write down every single morsel of food you eat, and every ounce of beverage with calories you drink. Estimate the portion sizes as accurately as possible, and weigh and measure everything. Get a food scale and measuring cup to do it accurately.

3. Then go to the following site to figure out how many calories you are consuming

4. Then to this site to estimate how many calories you burn all day (called the 24-hour energy expenditure (24-hrEE)

5. Then here to estimate your metabolic rate. Use the "Inactive" activity level for an additional cushion for underestimation of calorie intake.

You can post your diet-related questions to the Diet Community:

Once you know your 24-hrEE, and how many calories you consume, you can modify your intake accordingly, and/or increase exercise, so that you burn more than you consume. So if you consume 2000 and burn 1500, then you know you have to either cut back on your calories and/or increase your exercise to turn it around.

If all of this is too confusing, then just do #1 and write down everything you eat. If you do just that you'll lose weight.

Finally, weight loss can be difficult and lonely on your own. WebMD has excellent resources to help people lose weight. You can get all the support and expert guidance on your diet that you need by checking out the Diet Community and the Weight Loss Clubs. The support and guidance will be extremely helpful to you.

You can select one of the Diet Clubs based on how much weight you want to lose.

You'll find everything you need to lose weight on these sites.
Take care, Rich
