WEIGHT LOSS
All weight loss diets essentially come down to a matter
of calories. There is no magic. To lose weight, calories
expended must exceed caloriesconsumed. The form of the consumed
calories matters little, if at all. If
you eat fewer calories than you use, you will lose weight.
What does happen when you're dieting is that it becomes
the most important thing in your day. You pay attention
to what you eat. You exercise regularly. You become focused.
This increased awareness makes weight loss diets work. When
people regain their lost weight, it is because they have
lost their focus. Other things become more important. It
is worth remembering that the word diet comes from the Greek
and means "way of life." Diet therefore must include
not only eating well; but, regular exercise, rest and time
for yourself.
People lose weight on the Atkins Diet because they limit
calories. It
sounds like Dr. Atkins will let you can eat any amount you
want, but that is not so. Snacks, a major cause of obesity,
are virtually eliminated, as is alcohol. And because carbohydrates
are severely restricted, you cannot completely burn fat
and become ketotic; then you don't feel like eating. "Ketotic"
means that you have high levels of acidic substances called
keto-acids in your blood. The ketones produce a number of
side effects and are responsible for loss of appetite. Weight
loss is probably accentuated by the loss of ketone bodies
in the urine.
With all weight loss diets, there is probably an initial
weight loss
resulting from consumption of glucose stored in the liver
and muscles as glycogen. Certainly with low carbohydrate
diets (Atkins, Zone, Sugar Busters), this initial weight
loss of probably five to ten pounds occurs. Your body stores
sugar because your brain operates most effectively when
it uses sugar as fuel. Severe restriction of dietary carbohydrates
means that dietary sugar is not readily available for use
by the brain.
The Rice Diet achieves weight loss by restricting calories.
Patients
attending the residential Rice Diet Program eat between
800-1000
calories/day; after returning home, we recommend 1000-1500
calories/day for continued weight loss. Part of the initial
weight loss on the Rice Diet (usually 5 to 10 pounds in
an otherwise healthy person) is fluid. Here most of the
fluid lost is that stored throughout the body with sodium.
The very low sodium content of the Rice Diet mobilizes this
excess fluid. Most patients feel better when they are rid
of this excess water.
THERAPEUTIC EFFECTS
In addition to its benefits in terms of weight loss, the
Rice Diet
represents a powerful treatment for a number of chronic
metabolic
disorders. In fact, this therapeutic effect of the Rice
Diet was the origin
stimulus to its development and the sustaining reason for
its continuation.
Weight loss by any method will lower blood pressure and
cholesterol, benefit type 2 diabetes, lessen or eliminate
sleep apnea and pulmonary hypertension and help the symptoms
of arthritis and reflux. These effects are especially prominent
with the Rice Diet, but it is not known (though doubtful)
that the Atkins and other diets improve these conditions
to the same extent. Its very low sodium content is at least
partially responsible for the Rice Diet's striking therapeutic
effects. The Diet is more effective than diuretics in treating
heart failure, and over 70% of hypertensive patients treated
with the Rice Diet are able to discontinue antihypertensive
drugs while maintaining blood pressures lower than achieved
with drug treatment. The very low fat content of the Rice
Diet leads to lowering the blood cholesterol levels of participants
by an average of 13% (and by 22% when combined with lipid
lowering agents). The low fat content also enhances weight
loss. Even when Dr. Kempner, founder of the Rice Diet program,
tried to have patients maintain their weight by increasing
portion size and adding sugars to foods, patients still
lost weight. They just couldn't eat enough calories with
so little fat in the diet.
Weight loss (and possibly the fat restriction) rapidly improves
blood sugar levels in diabetes. More than three-quarters
of diabetic patients treated with oral medications are able
to discontinue their medications (with better glucose control)
after two to four weeks on the Rice Diet.
DIETARY HEALTH RISKS
High fat, high protein diets are thought to increase the
risk of cancer, heart disease and kidney disease. High protein
intake and ketosis cause loss of minerals: sodium, potassium
and calcium. Loss of calcium promotes osteoporosis.
The Zone and Sugar Buster diets are high in fat and protein,
and relatively low in carbohydrate. Unlike the Atkins diet,
they are not low enough to maintain ketosis. These diets
are based on the theory that insulin insensitivity (and
resulting insulin hyper) causes obesity. This theory runs
counter to the observations that obesity is the cause of
insulin insensitivity.
According to Dr. McDougall, Dr. Sears can not be on his
own diet (see www.drmcdougall.com
for details). Dr. Sears says he eats only 44 grams of fat
per day on his Zone diet. Dr. McDougall points out that,
in order to maintain his weight on the Zone Diet, Dr Sears
would have to be consuming 77 grams of fat and 173 grams
of protein per day: a high fat, high protein diet!
WEIGHT LOSS vs. WEIGHT MAINTENANCE
It is important to distinguish weight loss diets from weight
maintenance diets. A high-fat, high-protein diet that restricts
calories will lead to weight loss, but we also know that
a high-fat, high-protein diet is unhealthy as a maintenance
diet or we wouldn't be worried about diet at all. When calories
must be raised to maintain ideal weight, the number of grams
of fat, protein and carbohydrate increase even though the
percentage of calories coming from each nutrient remains
constant. Thus, an 800-calorie diet in which 30% of the
calories come from fat delivers only 27 grams of fat per
day. A 2500 calorie diet with 30% of the calories from fat,
delivers 83 grams of fat per day. All of the hoopla about
percentage amount of fat ignores the actual number of grams
of fat consumed each day. It is highly likely that the absolute
number of grams of fat is a factor in
producing disease. When the absolute number of grams of
fat eaten a day is low, the percentage of calories coming
from fat may be less important. Hence, limiting calories
(which must occur in any weight loss diet) limits fat and
lowers cholesterol. Only with diets based on grains, fruits
and vegetables can calories be increased without dangerously
increasing the amount of fat.
Changing habits is difficult at best. If you're going to
try to achieve
long-term weight control, it seems sensible do it by forming
healthy
habits. This means increasing vegetables, grains and fruits,
and decreasing dairy products, meat, processed and fast
foods and high fat snacks. Regular exercise is important.
An hour a day of walking will use the calories in about
30 pounds of body fat over a year. Most importantly, you
need to value and spend time with yourself. You'll know
what to do and you'll have the strength to do it.
