Your brains
weight regulating mechanism is called the “Fat Thermostat.”
The “setpoint”
of this fat thermostat influences your appetite, your energy and your level of
weight.
The weight regulating mechanism plays a crucial role in
the day-to-day drama of weight loss and weight gain. Once the fat level, or
setpoint, has been established, your weight regulating mechanism works
stubbornly to defend that level. Influence is exerted on two key functions,
your appetite and your metabolism.
The weight regulating mechanism will signal
you to take in more food when it feels that your supply of stored (energy) fat
is threatened. Likewise, it will decrease your body’s metabolic rate so you may
use less energy and burn fat at a lower rate.
The kinds of food you eat affect your setpoint, your
appetite, and ultimately, your weight. Intake of foods dense in fat, refined
carbohydrates, like sugar, and white flower stimulate a vicious weight gaining
cycle. Sugars and other refined carbohydrates are quickly digested 7 absorbed
into the bloodstream. Then you feel hungry again, and the cycle continues.
The rapid absorption of sugars creates an elevation in
blood sugar, which in turn causes an increase of insulin production. Insulin is
an essential hormone that allows the cells of the body to take in and burn
sugar from the blood stream. Excess insulin can actually cause increased fat
storage.
Most obese people have excessive insulin because their cells seem
to be resistant to it and the body produces more to overcome this resistance.
In the presence of excess insulin, a disproportionate share of sugar in the
blood stream is converted to fat and deposited if the fat stores.
Excessive insulin also seems to slow the breakdown of fats
for energy needs of the body. This triggers a signal for more frequent eating,
and a preference for sugar. You Feel tired and weak and move slowly to conserve
energy. When your body doesn’t get enough energy, it will start breaking
down muscle tissue, leaving you weaker and flabbier. What a dilemma!
What
you should always remember is:
The fat thermostat is set to maintain current weight.
The types of food eaten affect the setpoint. Foods high in
fat, sugar, and white flower actually raise the setpoint.
Physical activity affects the metabolic rate, and thus the
amount of energy wasted or conserved.
Other factors affect the weight regulating mechanisms are: Genetics, stress, hormones, pregnancy, drugs, and smoking.
Most important to remember is that you have control over
most of these weight-regulating influences – the type of food you eat and your
activity level.
