Cant Seem to Lose Weight No Matter How Little You Eat? Could Be Your Thyroid

Oprah announces to the world that she has a thyroid problem and automatically, and perhaps inadvertently, she helps perhaps millions of people with a particularly cruel illness. I wish I had that kind of star power. I could single-handedly wipe out a major cause of obesity.

Oprah Winfreys revelation last week that her weight problem is due to hypothyroidism has raised awareness of an ailment about which I have been preaching for years. She has done a great service to millions of overweight people.

Hypothyroidism is an often undiagnosed disease that causes that causes a host of problems including obesity, fatigue, infertility, dry skin and nails, and depression. Ironically, as devastating as it can be to the afflicted, hypothyroidism is surprisingly easy and inexpensive to manage if only it is diagnosed and treated properly. Thats a big if.

In my last book, Is Your Thyroid Making You Fat? (Warner Books, 2000) , I exposed a problem that Ive been seeing in countless patients over the years. So many of my patients suffer from an underactive metabolism caused by hypothyroidism and yet that fact was not discovered by their own doctors in spite of all the money spent on conventional laboratory tests.

In my book, I included my own 28-day self-test that I believe is more accurate than conventional lab tests in identifying an underactive thyroid.

Here are the numbers. In my South Florida medical practice, Siegal Medical Group, three out of four patients who follow our COOKIE DIET to the letter lose weight at a very impressive rate of about 15 lbs. per month. One out of four of them, however, initially loses at a slower-than-expected rate and those cases trigger my suspicion of hypothyroidism. The patient may say to me, My family doctor once did a blood test and said my thyroid is normal. That no longer impresses me. After treating a half million or so overweight patients over the last 50 years and analyzing tens of thousands of thyroid function lab tests, I know that we doctors cant always rely on the lab. To prove my point, Ive ordered the same thyroid function tests on the same patient several days in a row and gotten very different results each time.

Theres a second problem associated with the diagnosis and treatment of hypothyroidism: the drug of choice for treating the condition. The most commonly prescribed drug is levothyroxine, a synthetic form of thyroid hormone. Based on my experience with hundreds of thousands of patients, Im convinced that the natural form known as Armour thyroid or Thyroid USP is more effective. Natural thyroid is the only thyroid medication I prescribe for my own patients.

If youre one of the one out of four overweight people who insist that your weight is not warranted by the quantity you eat, its time to become a bit more assertive with the doctor who believes youre a glutton. You might even ask him or her to read my book, Is Your Thyroid Making You Fat? I put a chapter in the book just for doctors which offers suggestions on how to spot your hypothyroidism when the lab tests fail.

Wishing you good health,

Sanford Siegal, D.O., M.D.
