South Beach Diet Uses Glycemic Index
New York Times
MIAMI BEACH, Oct. 6 - Theories abound as to what has propelled
the South Beach diet to the center of the weight-loss universe
since the book bearing its name was published in April. Is it
the image it conjures, of bikini-clad models picking at tropical
fruit salad between sun-drenched photo shoots? Is it the aqua
shimmer of the book jacket, as eye-catching as the surf off
Ocean Drive?
Or is it that Dr. Arthur Agatston, the cardiologist behind
the latest low-carbohydrate, high-protein diet, is on to something?

Women's habits can reduce risk of diabetes
Harvard University Gazette Archives
Researchers from the School of Public Health and Brigham and
Women's Hospital have found that women who are not overweight,
exercise at least half an hour a day, and eat a diet rich in
fiber and low in glycemic index and trans fat dramatically
reduce their risk of Type 2 diabetes. The study results
appear in the Sept. 13 issue of the New England Journal of
Medicine.

VICKI WADLOW, a 53-year.old potter, stays busy with chores
on the Virginia farm where she and her family live. She has
led a vigorous life. She exercises regularly and spends much
of the year pursuing outdoor activities. Around the
time she turned 45, though, her slim figure gradually began

5 Simple Rules to Beat Hunger
Actually, one rule will do: Lower each meal's overall
score on the glycemic index (GI) - an indication of how
quickly a meal drives up your blood sugar - and you'll
feel full longer. The index ranks foods against glucose, a sugar
that scores 100. Under 50 is considered low; 50-70 is medium;
over 70 is high. The foods' scores are in parentheses below;
for an expanded list, see The Glucose Revolution Pocket Guide
to Losing Weight, written by leading GI researchers.

Good carbs, Bad Carbs
by Rita Schefrin, MA, RD
The nutrition armies continue to battle, wielding words and
theories, each camp claiming it possesses the weapon to win
the weight war and promote health. The purported great
debate is this: "Should we be eating a diet high in protein
(often accompanied by high saturated fat) and a low
carbohydrate, high in unrefined carbohydrate and low in
fat, or should mundane moderation be the maxim? Further,
could it be conceivable that there is a reconciling bridge,
a common thread, between these three seemingly opposing
theories? Such a bridge - increasingly gaining
acceptance, though still controversial - exists: the
glycemic index and glycemic load.

Glycemic Index - Lesson in Timing
by Sunny Blende, M.S., Sports Nutritionist
We all know we need carbohydrates for optimal performance in sports events, but
what are the best kinds of carbohydrate foods and when should we eat them? High
intensity exercise requires pre-exercise storage during exercise availability
and post exercise restoration of carbohydrates for muscle glucose energy.
Carbohydrates have traditionally been divided into "simple" carbohydrates
(foods causing large and rapid changes in blood sugar levels, usually sweet)
and "complex" carbohydrates (more nutritious, fiber-containing foods that
produce a sustained, slower change in blood sugar levels). These categories
can be misleading though because some "simple" carbohydrates such as fructose
produce a flattened blood sugar curve when eaten while other "complex"
carbohydrates such as whole wheat bread cause a large rise in blood glucose.
