Diet pills are designed to help overweight people suppress hunger and consequently lose weight. These are almost always pharmacological products, but there are also other herbal and natural alternatives. Chemical diet pills are always associated with many risk factors along with certain benefits. Some were initially developed with afetamines, such as digoxin and dexedrine, which are stimulants that can increase heart rate to high-risk levels.

People with obesity problems usually have to lose weight due to pre-existing or developing heart disease. In this case, diet pills containing amphetamines or other similar stimulants will present a definite risk. Although they will curb the desire to eat, they also disrupt normal sleep habits; result in anxiety and can be highly addictive. In fact, it’s important to remember that almost all diet pills work by interfering with some natural mental and physical functions.

Modern pills will work by curbing hunger, increasing metabolism, and altering the absorption of some nutrients in the food we eat. Most fat burning supplements will prevent the body from absorbing fat. When someone consistently eats foods that are high in fat, these pills can be effective. But, they will give the results by short-circuiting the body’s tendency to retain fat in the tissues. As a result, the use of diet pills is never a long-term option for weight loss.

In recent years, some of the active ingredients in these pills were fenfluramine and phentermine. These will work by obstructing certain pathways of metabolic responses that contribute to weight gain. When these are used in combination, they will also apparently produce significant results. However, medical authorities withdrew fenfluramine and its derivatives from the market after studies showed that they could damage the heart valve. But, the combination of phentermine and topiramate is still used. This is also the case for combinations of bupropion with naltrexone and zonisamide.

Some pills are currently under research and development to overcome irregularities such as insulin resistance, where the body’s normal production of insulin is not adequate to generate a normal reaction from fat. On top of that, pills are also being developed with the intention of correcting conditions where the levels of lipids or fat molecules in the body tend to be unusually high. From a technical perspective, these pills cannot be called diet pills as they will not reduce food cravings. However, they can be quite effective if used in combination with a proper weight loss diet.

People have a tendency to overindulge for different reasons, most of which are psychological rather than physical. As a result, you can find pills specifically designed to reduce unnecessary urges to eat, as they may correct a psychiatric or psychological disorder. However, these are not really diet pills, but they will have the desirable effect of helping obese people control their appetite.
