1. The most common appetite suppressant pills are available over the counter and mainly work on the brain chemistry. These are the kind of diet pills that work for a short time as the user does not feel that much hungry and eats less. However, these kind of appetite suppressant pills are only good for short-term weight loss. Eventually, when the user returns to eating properly, the lost weight returns – often much too fast. These kind of pills also do not impact the overall fat-retention capacity of the body. People using only these pills for fat loss reach a plateau much faster and also suffer the impact of dieting.
2. Natural appetite suppressant pills are made of natural extracts that were used during famines and when people wanted to undertake long journeys hundreds of years back. Some plants have the natural ability to suppress hunger. Hundreds of years back, in all cultures, these extracts were the only way to save people during famines. With no modern methods of travel available, people wanting to travel far for economic reasons had to use these extracts to be able to save money and not worry about getting hungry all the time. The weight-loss industry has made millions already by using these extracts in fat-loss pills. Two most common natural extracts are Hoodia Gordonii and Caralluma – flourishing in desert-like or semi-desert like climate. Most experts say, appetite suppressant pills with natural extracts do not cause side effects but you must consider that not pills are approved by the FDA. Some of these pills may still affect the liver and blood sugar. Most natural supplements have been recently launched and their potential long-term effects have not been studied.
3. Prescription appetite suppressant pills have been used for several years and the FDA has approved most of them. These, typically include:
   • Meridia: That works on specific chemicals in the brain to suppress hunger. The FDA approved Meridia in 1997. Side effects of Meridia may include headaches, constipation, insomnia and dryness of the mouth.
   • Ephedra: This kind of appetite suppressant pill is used with several herbal supplements for weight loss and is considered a harmful stimulant. It can cause irregular heartbeats, high blood pressure, even seizures, tremors, heart attacks, strokes, insomnia and nervousness.

Whenever you decide to take any kind of appetite suppressant pills, you must consult your doctor even if you don’t have a medical history. No appetite suppressant can give you long-term fat loss benefits unless you eventually improve your overall dietary habits.

Integrating proper nutrition with a proper exercise program at least thrice a week can alone ensure proper and permanent fat loss. You can use appetite suppressant pills to trigger fat loss but to maintain the loss, you will need to overhaul your lifestyle.
