Some of us have that problem of gaining weight, and others have trouble loosing. It certianly has little to do with how much you eat, though a doc friend has told me the amount of times I eat and what times I eat. Finaly I have gained weight, my wife too.

perhaps it could be your diet has changed; are you eating more or less?  Usually sudden weight loss (keeping all other variables constant) indicates a health problem.  Most people will tell you to go see a physician...

Sounds like phentermine, which is a weight loss medication.  It was famous as half of the drug phen-phen.  The numbers are probably quantitative labels.

Exercise.\n\nWhen you lose a lot of weight by not eating as much and you don't exercise all of that extra skin that was supporting the fat you once had will still be there.  You have to work out to get that to firm up.

You don't mention your height or current weight, but my guess is you may not be eating enough for your body.  You could be going into starvation mode where your body will hold on to every single calorie, every single ounce.  I would suggest you shake it up a bit.  Try eating a bit more one day, exercising less another or skipping the exercise altogether for a day.  Change the types of foods you eat.  See if that helps you.  You could also talk to your doctor who'd be able to let you know more specifically why you're not losing.

It sounds like you are at a pretty good weight.  You have to be happy with your body, nobody else.  If you feel underweight gain a few pounds, but if you feel overweight lose a few pounds.  Its you being happy with your body that is important.

It maybe a thyroid problem.  You should go see your doctor.  If it is a thyroid problem you may start to gain weight.

You should have a medical check up.  hyperthyroidism, diabetes, viruses, malabsorption syndromes, other stuff can cause inability to gain weight with effort.

A few years ago, I lost 20 pounds simply by reducing my portion sizes.  There was a period where I felt hungry shortly after a meal but I would snack on "negative calorie foods" (those fruits and vegetables which supply fewer calories than your body expends in metabolizing them).  I felt much better about myself afterwards and have since been exercising which makes it easy to keep the weight off.

The weight loss could very well be the cause. When you lose weight, your hormones change. Providing you did not have sex. Otherwise wait and see. If you don't get it soon, speak to the school nurse. She will definitely be able to help you.

Weight gain or loss. Because your body is trying to compensate for lost fluids and sugar, you may eat more than usual and gain weight. But the opposite also can occur. You may eat more than normal, but still lose weight because your muscle tissues don't get enough glucose to generate growth and energy. This is especially true if you have type 1 diabetes, in which very little sugar gets into your cells. In fact, most people with type 1 diabetes are at or below their normal weight. \n\nu can also go to this website to learn more of type 1 diabetes mellitus\n\nhttp://www.uchsc.edu/sm/endo/brochures/diabetes_type1.pdf

In re: to the snide comment above - POS is a *perfectly* acceptable moniker for the disease.  There are several ways in which to refer to the illness.  I knew exactly what you meant.  And secondly, no, it can't simply be cured by weight loss.  People need to check their facts before coming here and insulting others.  The second answer was much more on target and had some good info, but I also recommend reading through http://www.4woman.gov/faq/pcos.htm for details and info.  It is possible to live well with PCOS and obtain effective treatments to help you feel better.  Good luck.

To lose weight, you must burn more calories than you take in. So, if your normal daily activity level does not burn more calories than you take in, you probably won't lose weight. Maybe increasing your daily activity level (not by actually working out) by walking a little more, less sitting in front of the TV, and, cutting back on the amount of food you eat (and reducing the amount of fast / junk foods), you just might lose a little weight.

No it does nothing unless you are under stress that is making you gain weight.

Don't worry about it. It'll come back to you. You probably stress too much. That can cause weight loss.
