There many kinds of weight loss pills intended to help consumers shed unwanted pounds from their bodies. Among them are herbal diet pills which are made from natural ingredients that speed up body metabolism or suppress appetites. To speed up metabolism caffeine and green tea extract are added. Ingredients such as alfalfa and conjugated linoleic acid (CLA) suppress the appetite.

While physical exercise takes a lot of time and effort, diet pills seem effortless. It is not surprising that many are attracted to them. Meanwhile experts are divided over whether they actually work or not.

Researches have established that low fat products increase the amount of fat excreted by the body. Daily intake of 2-3 portions of low fat dairy products might be more effective.

Some herbal diet pills can offer certain proof of effectiveness or they wouldn’t last long in the market so they are worth a try. Taking something that might work always provides a psychological boost to the user. However, most herbal pills can offer very little evidence of effectiveness and many have side-effects. When considering herbal diet pills it is best to consult a doctor.

Overall, the best way to shed excess pounds is still the traditional ones - regular exercise, adequate sleep and balanced intake of nutrition- perhaps, not as easy as popping pills, but definitely more effective.

As the world’s communities achieve a certain degree of progress and advancement, their populations of obese and overweight also significantly increase, creating a great demand and huge expenditures for weight loss programs, including diet pills and weight loss pills. This year, America will probably spend around $100 billion in economic costs for its obese and overweight population of about 127 million (not counting the children); of this, the medical related cost could well surpass $80 billion. Similarly, with increasing levels of affluence, 27.3% of the adults in China are now overweight or obese.

One can therefore imagine the zealousness of today’s scientists to find a safe and lasting cure for this alarming malady. And the prospects are truly encouraging. Scientists are now working at the gene level, and have now isolated a gene in laboratory mice that when silenced results in a radical decrease in fat accumulation. Scientists have also met with positive results in experiments with the gene E4-ORF-1 from the Adenovirus 36, a virus now identified as responsible for some obesity cases.

Medical companies are also developing better lipase inhibitors, where the inhibitors are combined with polymers, which work to eradicate some of the inconvenient side effects traditionally associated with lipase-inhibiting drugs. With these breakthroughs, the world may soon have safe, convenient and effective diet pills and weight loss pills with long-term - even permanent – benefits.
