Are Diet Pills Effective?
By Aytac ..Sengul45 Aytac ..Sengul12
With so many pills claiming to offer ‘guaranteed results’ and ‘massive weight loss’, it has become difficult to ascertain which pill is actually effective. To better understand which pill is effective and which one is not, it is important to know the various pills available in the market.
Prescription pills
Prescription pills like Meridia and Xenical are some of the few pills that are available only on a doctor’s prescription. The sale of Meridia and Xenical is regulated closely by the FDA and requires patient’s to meet certain criteria before they can be prescribed Meridia or Xenical.
Over the counter pills
Although the FDA has recently approved a few drugs to be added to the list of over the counter pills, there has been considerable debate over which drugs should be sold over the counter. Till 2000 over the counter pills contained a substance called PPA (phenylpropanolamine), but recent studies have pointed out that PPA can increase the risk of a stroke and very few over the counter drugs now contain PPA.
Herbal pills
The number of herbal pills available in the market exceeds the number of prescription and over the counter drugs available. Herbal pills are usually a combination of various botanical extracts like Hoodia, bitter guard, bitter orange and green tea. The effectiveness of herbal pills is still unclear, and no single herbal pill has been proven effective in inducing weight loss. In addition, various metals like chromium have also been used in pills but the truth is that the effectiveness of herbal pills is still unproven.
How do control pills work?
Prescription pills use various mechanisms to help a person loose weight. Prescription pills like Meridia , Tenuate and Fastin affect the hypothalamus which is responsible for regulating the feedback mechanism that controls the stomach’s feeling of being ‘full’. In essence, a person feels full with a relatively small meal or sometimes without eating anything at all. Other prescription pills like Orlistat inhibit the action of an enzyme called lipase

which is responsible for breaking down fat in the body. pills like Orlistat are responsible for inhibiting the action of Lipase thereby reducing the absorption of lipids (fats) in the body.
Most herbal pills are designed to decrease an individual’s appetite and thereby reduce their daily calorific intake. Although various herbal pills claim to be effective and ‘guarantee’ results, very few herbal pills have undergone clinical testing to establish their effectiveness. On the other hand, OTC (over the counter) pills contain caffeine and other synthetic substance like synephrine that supposedly increase the metabolic rate of the body, thereby increasing the rate at which calories are burned up by the body.
In essence, different pills have different mechanisms for helping people loose weight. What is equally true is that not all pills are as effective as they claim they are.

What are the side effects of pills?
Lipase inhibitors like Orlistat remove unabsorbed fat through the intestine and common side effects of consuming Orlistat include cramping, gas and diarrhea. In addition, people using pills like Orlistat are also advised to consume multivitamins as lipase inhibitors also reduce absorption of vitamins. People using pills like Meridia are advised to look out for common symptoms like high blood pressure and increased heart rate. In fact, people with existing heart problems are usually advised not to use pills like Meridia (as sibutramine has a tendency of interfering with the normal functioning of the heart). There is a misconception that herbal pills are safe, and even ‘all natural’ pills have various side effects like diarrhea, constipation etc.
