A large number of overweight conditions result from the physiological addiction to certain foods or food cravings. The cravings create a sense of hunger which is usually a “false hunger”. Those who experience the food cravings find that they have an intense and uncontrollable desire for certain foods that are not required or needed to sustain life. The desire stems from a combination of different factors that are emotional, biochemical and hormonal. Using an appetite suppressant can help to reduce this problem.
A number of everyday natural foods found in the home can be used for suppressing the appetite. Some people also resort to using prescription drugs, or over-the-counter OTC phentermine drugs. The drugs often come in the form of pills or capsules. One of the most common prescription suppressant drugs is phentermine. The appetite suppressant works by tricking the body into thinking that it is full. Those who take the drugs feel like they are constantly full and as such, they do not crave food. The appetite is decreased because the drug causes an increase in serotonin or catecholamine. These are two brain chemicals that are responsible for appetite and mood.
The main reasons why diets fail is because people start feeling hungry and inevitably reach for the food. Most diets recommend cutting out certain foods. However when this is done, hunger sets in. The need for food is a natural human need. No one likes to feel hungry and when they do, they will always do whatever it takes to get rid of the feeling. This usually means ignoring the diet rules, and reaching for the food. It is with this in mind that many manufacturers of diet pills have resorted to using ingredients that suppress the appetite in their formulas. They know that the only way a product will work is if the user does not feel hungry. Trying to lose weight by sheer will is very difficult for most people.
