Ephedrine is a naturally occuring central nervous system stimulant obtained from the plant Ephedra equisetina. It is now also produced by chemical synthesis, the synthetic product being marketed in the form of its salt, ephedrine sulfate; it occurs as a white crystalline powder with a bitter taste, soluble in water and very soluble in alcohol. Ephedrine is closely related in structure to methamphetamine, although its CNS actions are much less potent and also longer-acting than those of the amphetamines. Its peripheral stimulant actions are similar to but less powerful than those of epinephrine (also called adrenaline), a hormone produced in the body by the adrenal glands. Even the most effective diet pills including ephedra diet pills are only meant to be taken for a short period of time,  usually for six to nine months or less. During that time, ephedra supplements or another type of quality fast weight loss diet pills can trim anywhere from 10, 20 or even 60 or more pounds depending on your body type, your diet and your lifestyle. Usually after six to nine months, your body will develop a tolerance to the ephedra fat burners you are using and you will reach a weight loss plateau, making the weight loss pill you are taking ineffective. Ephedra pills work better of you don’t take them for more than 12 days straight without taking one or two days off to give your body a rest. At that time you can always select another quality weight loss pill or fat burner and continue to your goal realizing that trying to lose to much weight to fast could be unhealthy.  Ehpedra diet supplements and other quality diet supplements are meant to help lose weight more quickly than possible with diet or exercise along.  However,  if you don’t also change some of your eating habits and follow a more healthy eating and some type of exercise plan, the weight in many cases will eventually come right back. In summary, work out a system that works for you, and fits your lifestyle. Use common sense, don’t over do it, have some patience, and success will come especially if you can cut out all or most soft drinks and other junk (FAT) food at the same time while using these proven diet supplements
