Carbohydrates for Overweight

Which carbohydrate can be used to reduce overweight and why.


Our source of carbohydrates is plants. Plants compose carbohydrates in
two forms:

A- Storage carbohydrates which are:
1- Easily digested to release glucose quickly.
2- Of compact size for space economy of the plant.
3- Of spacial configuration that is compatible with Amylases
Starch represents this group of storage carbohydrates.

B- Structural carbohydrates which are:
1- Of large intra-molecular spaces to hold water inside the plant.
2- Not liable to digestion by carbohydrate digesting enzymes to
guard against decay of living plants.
3- Of rigid nature for stature of plants ( they have no bones).
Cellulose & Hemicellulose represent structural carbohydrate group.

When humans eat digestible carbohydrates (starchy food),their digestion
starts as soon as they are admixed with saliva where its amylase splits
starch into linear fragments that is ended with formation of soluble
glucose which is absorbed through the intestine.
When they eat indigestible carbohydrates (fibers), the later acquire
volume and weight all the way till excreted almost undigested and
unchanged.


When we compare the digestive trip of starch and fibers, we find that
starch is disappeared from the digestive tract easily to appear in the
blood in the form of glucose,ie. easily earned large amount of calories
while fibers(cellulose) gets heavier along the whole trip and the
digestive tract works harder to push down the water saturated fibers
while extracting a small amount of calories present in digestible
materials adhered to fibers,ie. the body pays calories to get rid of
fibers.

Imagine immersing 2 similar pieces of sugar and sponge in water for a
while, the sugar will disappear and the sponge will be saturated with
water needing extra work to be moved off its place. This is what
exactly happens upon eating starch and fibers, the starch is
represented with sugar and the fibers represented with sponge in our
example.

If you consume a digestible carbohydrate(bread,pasta,rice,desserts..etc
of 400 calories and this carbohydrate requires 150 calories to digest
then you gain 250 calories that if not consumed,it would be stored as
fats. But if you consume 100 grams of vegetables that have 25 calories
and need 80 calories to digest, then you'll lose 55 grams after
excreting it.


Structural carbohydrates (cellulose) form the skeleton of any vegetable
or fruit and it is the digestible carbohydrates amount that determines
the appreciation of a plant to be of a high negative calorie value.
There are up to 100 plants which contain a plenty of indigestible
carbohydrates and minimal digestible carbohydrates.
Some of these plants are:
Grapefruit-Lettuce-Cabbage-Cucumber-Broccoli-Berries-Beat-Apple-Carrots
Chili-Cauliflower-Celery-Garlic-Onion-Papaya-Orange-Lemon-Spinach-Mango
Zucchini-Asparagus.


Fibers also form fecal bulk that guard against possibility of serious
constipation that results from consumption of diets containing much of
white flour and meat.
