When it comes to weight loss, many people seek quick and effective solutions. Diet pills, particularly those approved by the Food and Drug Administration (FDA), are among the most popular options for individuals looking to lose weight safely. But with so many options available, how do you know which is the best diet pill for you?
This article will explore what the FDA-approved diet pills are, how they work, and provide a comprehensive guide to the best options currently available.
What Are FDA-Approved Diet Pills?
Before diving into specific products, it’s essential to understand what FDA-approved diet pills are. The FDA regulates medications and treatments to ensure their safety and effectiveness. When a diet pill is approved by the FDA, it means that the pill has undergone rigorous clinical testing and has been proven to meet strict safety standards.
These diet pills are usually prescribed for people who have a body mass index (BMI) of 30 or higher or those with a BMI of 27 or higher who also have weight-related conditions like high blood pressure or type 2 diabetes.
How Do FDA-Approved Diet Pills Work?
FDA-approved diet pills work through various mechanisms. Most fall into one of the following categories:
1. Appetite Suppressants
These drugs work by reducing your appetite or making you feel full sooner. They affect the central nervous system by increasing levels of neurotransmitters that reduce hunger signals. Common appetite suppressants include phentermine and similar medications.
2. Fat Absorption Inhibitors
Some diet pills prevent your body from absorbing fat from the food you eat. These drugs work in the gastrointestinal tract by blocking enzymes that break down fat. As a result, the fat is eliminated through bowel movements. Orlistat is the most well-known fat absorption inhibitor.
3. Metabolism Boosters
Certain medications aim to increase the number of calories your body burns by enhancing metabolic activity. By speeding up your metabolism, these pills help you burn more fat even while at rest.
4. Glucose Regulators
Some diet pills help control how your body processes glucose, which can reduce fat storage and help you lose weight.
Now that you understand how these medications work, let’s explore the best FDA-approved diet pills currently available.
The Best FDA-Approved Diet Pills
1. Phentermine/Topiramate (Qsymia)
What Is Qsymia?
Qsymia is a combination drug that contains phentermine (an appetite suppressant) and topiramate (an anti-seizure medication). It works by reducing hunger and helping you feel fuller for longer.
How Does Qsymia Work?
Phentermine stimulates the release of brain chemicals that curb hunger, while topiramate enhances feelings of fullness. The combination of these two drugs leads to effective weight loss by reducing calorie intake.
Who Can Use Qsymia?
Qsymia is typically prescribed to individuals with a BMI of 30 or higher or those with a BMI of 27 or higher who have weight-related health issues.
Effectiveness of Qsymia
Clinical trials have shown that Qsymia can help users lose an average of 5-10% of their body weight within the first year of use. It is especially effective when combined with a reduced-calorie diet and regular physical activity.
Potential Side Effects
Some common side effects of Qsymia include dry mouth, constipation, dizziness, and tingling sensations in the hands or feet. More serious side effects can include increased heart rate and mood changes, so it’s important to use this medication under a doctor’s supervision.
2. Liraglutide (Saxenda)
What Is Saxenda?
Saxenda is an injectable medication that mimics a hormone in the body called glucagon-like peptide-1 (GLP-1). This hormone regulates appetite and food intake.
How Does Saxenda Work?
By acting like GLP-1, Saxenda helps to reduce hunger, slow gastric emptying, and increase feelings of fullness. This leads to reduced calorie consumption and weight loss.
Who Can Use Saxenda?
Saxenda is approved for individuals with a BMI of 30 or higher or those with a BMI of 27 or higher who also have at least one weight-related medical condition, such as high cholesterol or diabetes.
Effectiveness of Saxenda
In clinical trials, patients using Saxenda lost an average of 5-10% of their body weight over a year. This is comparable to other prescription weight-loss medications.
Potential Side Effects
Common side effects of Saxenda include nausea, vomiting, diarrhea, and constipation. Serious side effects may include pancreatitis, gallbladder disease, and kidney problems. Always consult a healthcare provider before starting Saxenda.
3. Orlistat (Alli, Xenical)
What Is Orlistat?
Orlistat is available both as a prescription (Xenical) and over-the-counter (Alli). It is a fat absorption inhibitor that works in the digestive system to prevent the absorption of about 25% of the fat you consume.
How Does Orlistat Work?
Orlistat blocks the action of enzymes that break down dietary fat in the stomach and intestines. This means that some of the fat you eat is not absorbed and is instead excreted through bowel movements.
Who Can Use Orlistat?
Orlistat is recommended for individuals with a BMI of 30 or higher, or those with a BMI of 27 or higher who have weight-related health problems.
Effectiveness of Orlistat
Studies have shown that Orlistat can help users lose about 3-5% of their body weight over a year. While this may seem modest compared to other medications, it can be effective for people who need a safe, long-term solution.
Potential Side Effects
Because Orlistat affects fat digestion, its most common side effects are gastrointestinal issues, such as oily or fatty stools, gas, and frequent bowel movements. These side effects can be minimized by sticking to a low-fat diet.

4. Naltrexone/Bupropion (Contrave)
What Is Contrave?
Contrave is a combination of two medications: naltrexone, used to treat addiction, and bupropion, an antidepressant and smoking cessation aid. Together, they influence the brain’s reward system and reduce food cravings.
How Does Contrave Work?
Contrave works by regulating parts of the brain that control cravings and the desire to eat. This helps reduce overeating and emotional eating, making it easier to stick to a weight-loss plan.
Who Can Use Contrave?
Contrave is approved for people with a BMI of 30 or higher, or those with a BMI of 27 or higher with at least one weight-related condition, such as type 2 diabetes or high blood pressure.
Effectiveness of Contrave
Users of Contrave have been shown to lose an average of 5-10% of their body weight within a year when combined with a reduced-calorie diet and exercise.
Potential Side Effects
The most common side effects of Contrave are nausea, headache, and constipation. However, some users may experience more severe side effects like increased blood pressure and mood changes, so it’s essential to monitor these symptoms with a healthcare provider.
Choosing the Best Diet Pill for You
When it comes to selecting the best FDA-approved diet pill, there is no one-size-fits-all solution. Your choice depends on various factors, including your overall health, weight-loss goals, and any medical conditions you have.
1. Consult a Doctor
Before starting any weight-loss medication, it’s crucial to consult with a healthcare provider. They can help determine which pill is the best option based on your individual needs and medical history.
2. Consider Side Effects
Each FDA-approved diet pill comes with potential side effects. Weigh the benefits of the medication against its possible drawbacks and discuss any concerns with your doctor.
3. Adopt a Healthy Lifestyle
While diet pills can be a helpful tool for weight loss, they are most effective when combined with lifestyle changes such as a healthy diet and regular exercise. Long-term success requires making sustainable choices for your health.
Conclusion
FDA-approved diet pills can be an effective aid for weight loss, especially for individuals struggling to lose weight through diet and exercise alone. The best diet pill for you will depend on your unique health profile and weight-loss needs. By consulting a healthcare provider and combining these medications with lifestyle changes, you can achieve long-lasting weight loss and improve your overall health.
