Water Issues 
Excerpt from "The Arizona Republic"
Water-loss risk high for swimmers, kids, seniors
by Thomas Ropp

Valley health professionals estimate that two of three Arizonans are dehydrated and don't know it.

And just because you hang in a pool, don't think you're immune. Backyard swimmers are particularly susceptible to water loss.

"You don't feel it, but you perspire when exercising in water, too," said Dr. Donald Robertson of the Southwest Bariatric Nutrition Center in Scottsdale. "Swimmers lose water through their skin and don't realize it."

Ropp further writes: "…children and seniors are also at high risk for water loss. Children dehydrate quickly because of their frenetic movements while playing and chasing. … Seniors are vulnerable to dehydration because they forget to drink or purposely avoid fluids for fear of incontinence."

So remember: Drink plenty of water during hot weather!

A colleague of Dr. Robertson's recently emailed him the following.
After reading it, it does make one wonder.

Recently I participated in a focus group with nine other doctors — sponsored by a pharmaceutical company — to discuss a new orally inhaled insulin. After an hour, the leader invited us to go behind the one-way mirror to watch the insulin device presented to a group of 10 obese diabetics. The leader obtained biographical information from each diabetic patient. After the diabetics left, the doctors were brought back to discuss the reactions of the diabetics to the insulin device. I was upset, and said:

"This has nothing to do with the subject of the evening, but I have to say this: We just saw a group of 10 obese diabetics, taking an average of six medicines for diabetes, hyperlipidemia, hypertension, acid reflux, neuropathies and gout. Wait a minute! These people don't have six different diseases. They have one disease, obesity. Cure that and the other problems go away. And yet none of their doctors even discussed obesity with them!"

An article in the current "Archives of Internal Medicine" shows that when overweight patients saw their doctors for a "physical," only 5.7% of the doctors discussed their weight with them. [Furthermore] when obese patients saw the doctors, only 37% of the doctors told them to lose weight. How the Hades do we expect to make progress with Congress, the press and insurance companies if our own colleagues are so benighted?"



SBNC's Weight-loss Program:

“What we advocate is a high protein, moderate carbohydrate and low-fat eating plan. As long as you eat plenty of carbohydrates, the body will burn that and leave the fat alone.

The diet of choice ten years ago was a high carbohydrate, low-fat diet. What the people really were getting, though, was a high carbohydrate/high-fat diet because of invisible fat — fat found in all vegetables, grains, most nuts, eggs, even tofu. People were exercising six hours a day and eating all these carbohydrates with invisible fat in them. Sort of a one step forward, two steps back situation.

Basically, if you eat enough carbohydrates to sustain the body’s needs, the fat is going to stay. You’re not going to lose weight; you may even gain weight. If you cut carbohydrate intake enough, the body, which first burns carbohydrates as fuel, has no choice but to burn the stored fat instead.”

On a related issue:
A rapid return to increased carbohydrates can result in elevated blood volume with fluid retention. These are early warning signs of insulin resistance. They usually disappear when dietary protein is increased and the carbohydrates are at the prescribed level.

Hyper-insulimia and insulin resistance are the new buzzwords for 1999. They are closely related. The problem is increased insulin production with cellular resistance in accepting insulin-mediated nutrients. Eventually, without medical dietary intervention, this condition can progress. The result can be Metabolic Syndrome X manifested by CAD (coronary artery disease), high blood pressure, high blood sugar, high cholesterol, low HDL, high LDL and increased incidence of certain types of cancer, such as colon, breast and prostate to name a few. Basic research is hot on the cause.

Visceral fat means fat stored deep in the abdominal viscera, such as the small bowel, colon and liver. It is much more dangerous than the subcutaneous fat found just under the skin. A basic index of the amount of visceral fat can be obtained by measuring the waist at the level of the navel. A reading of 35 inches for women and 40 inches for men is felt to be a predictor of this, now called The Metabolic Syndrome X.
