Phentermine diet pills have been around for almost 50 years. Most commonly used for people with health issues related to obesity, phentermine diet pills are not for the 'casual' dieter who is trying to lose that last ten pounds. The reason that phentermine diet pills are even still around when there are so many other choices is because it has been proven to work and is fairly inexpensive with relatively few side effects. These pills are called appetite suppressants. This is because they send a message to your brain convincing you that your body is full. They also give you a boost of energy which is good because the phentermine diet pills work best with exercise and a specialized diet plan. These pills should only be used under the direction of a doctor and are most effective if used for short periods of time, such as three to six weeks. Your body adjusts to it after a while and it becomes ineffective. You will need to keep up with your specialized diet and exercise when you give up the diet pills or you will very quickly regain the weight.
