The Anatomy and Physiology of Weight Loss

The Primary Causes of Obesity

There is no one cause of obesity. Some people are more easily able to identify the reasons why they are unable to lose weight and keep it off once they have lost it. For some individuals, the origin of the weight gain was a basic shift in lifestyle. They may have gotten married, had a work-related injury, experienced cultural pressure, had poor exercise patterns or changed their exercise patterns due to a sports injury, had a baby, or quit smoking. For others it is hereditary factors. It may be a medical problem with neurological regulators or natural hormonal factors such as thyroid gland dysfunction. It may also be a digestive disorder, blood sugar disease (hypoglycemia or diabetes), enzymatic activity, brain mechanisms, genetic predisposition, or they may simply take in more calories from the food that they eat than they expend. Let’s take a closer look at a few of these factors and how an effective herbal weight program might reduce their influence.

Enzymatic Activity

The enzyme lipoprotein lipase (LPL) is a factor that may influence obesity. LPL helps the body store excess calories in fat cells. The enzyme is manufactured in fat cells and is transported to the capillaries, where it breaks dietary fat into tiny particles that penetrate the membranes of these fat cells. The process becomes a vicious cycle of cells continuously collecting fat and LPL levels rising, which causes more fat to be collected from the bloodstream. Reducing caloric intake decreases LPL levels, but when a person begins to overeat or even return to normal meal patterns, LPL levels may become higher than before the diet began. Using herbs, such as Garcinia cambogia extract and Gymnema sylvestre, can naturally reduce the tendency to overeat and thus reduce the factors that cause an increase in LPL levels.

Brain Mechanisms

Many obesity experts believe that there is a mechanism in the brain known as the adipostat, which tells the body how much fat to store. This is, in turn, based on a predefined weight that the body wishes to maintain. As your body uses fat through your daily activities, the brain regulates the usage or storage of energy until your fat levels
maintain this preestablished goal. Sometimes the adipostat may actually set a fat storage level that is unhealthy. In such a case, simply reducing your caloric intake may not reduce weight so easily.

While you may be cutting back on fat and calories, the brain may be sabotaging your efforts by restoring your original, excess weight bycausing you to consume more calories due to hunger sensations.

There is a belief among many researchers that there is a specific hormone in the body known as HGH (human growth hormone), which helps people to burn fat and build muscle. HGH is present at high levels in children so that they convert fat quickly into muscle and meet the needs of rapidly growing bodies.

Research has indicated that this fat-burning hormone is released at a slower pace as a person reaches thirty years old and virtually stops after thirty. Nutritional scientists also believe that this hormone is dormant in individuals who are plagued by obesity whatever their age. The body stores HGH in the pituitary gland and releases it in response to sleep, exercise, fasting, and by the amino acids L-arginine, L-ornithine, and L-lysine.
Through metabolic and behavioral regulation, the pituitary and adrenal glands control eating patterns. They are able to recognize and respond to certain signals that indicate hunger or the existence of high-fat storage in the body. How the body recognizes this key information is defined by numerous variables. One of these variables is leptin. Leptin is an enzyme that signals the brain when fat storage is high. Fat cells release leptin; levels rise as more fat is stored in the cells. If fat storage falls, then lower leptin levels signal to stimulate appetite. Certain herbs have been shown
to influence the regulation of metabolic and behavioral patterns
