PERMANANT WEIGHT CONTROL . . .
by PCRM
Many people believe
that to lose weight they have to go on a low-calorie
diet. That often means starving oneself until the diet
is no longer tolerable. Then the weight goes right
back on—and then some. Happily, there is a much better
way. It is easy and offers many other health benefits,
too.
No More Diets
The
first thing to realize is that changing eating habits
must be more than a short-term means to an end. Changing
eating habits is the cornerstone of permanent weight
control. There is no way to “lose 20 pounds in two
short weeks” and make it last. Very-low-calorie diets
cause two major problems: they lower one’s metabolic
rate, making it harder to slim down, and they lead
to bingeing.
Fat Versus Complex Carbohydrates
The
old myth was that pasta, bread, potatoes, and rice
are fattening. Not true. In fact, carbohydrate-rich
foods
are perfect for permanent weight control. Carbohydrates
contain less than half the calories of fat, which
means that replacing fatty foods with complex carbohydrates
automatically cuts calories. But calories are only
part of the story. A recent study in China found that,
on the average, Chinese people eat 20 percent more
calories than Americans, but they are also slimmer.1
Part of this is due to the sedentary American lifestyle,
but there is more to it than exercise alone. Earlier
studies have shown that obese people do not consume more
calories than non-obese
people—in many cases, they consume less.2,3 The body treats
carbohydrates differently than fat calories. The difference
comes with how the body stores the energy of different
food types. It is very inefficient for the body to store
the energy of carbohydrates as body fat—it burns 23 percent
of the calories of the carbohydrate—but fat is converted
easily into body fat. Only 3 percent of the calories
in fat are burned in the process of conversion and storage.4
It is the type of food, not so much the quantity, that
affects body fat the most.5
Protein
Although
protein and carbohydrates have almost the same number
of calories per gram, foods that are high
in protein—particularly animal products—are usually
high in fat, too. Even “lean” cuts of meat have much
more fat than a healthy body needs. And animal products
always lack fiber. Fiber helps make foods more satisfying
without adding many calories, and it is only found
in foods from plants.
Exercise
Exercise
is essential. Aerobic exercise speeds up the breakdown
of fat in one’s body and makes sure that muscle
is not lost. Toning exercises and weight-lifting
help firm muscles and increase muscle mass. A
combination of exercises will help one achieve a slimmer,
firmer, healthier body in a shorter period of time.
The trick is to find activities that one enjoys and
that can fit one’s lifestyle. Walking is popular because
it requires
no special equipment and can be done anywhere
at anytime.
Conclusion
The
best weight control program is a high-complex-carbohydrate,
low-fat, vegetarian diet complemented by regular exercise.
This is the best choice for a healthier, longer, happier
life.
