Losing weight is a struggle that many of us face, and it’s not uncommon to feel frustrated and helpless when we’re not seeing the results we want. With so many fad diets and miracle pills on the market, it can be hard to know what really works and what’s just a waste of time and money. But what if there was a medication that could help you lose weight, and it’s not a brand-new, untested drug? Enter naltrexone, a medication that’s been around for decades, but has recently gained attention for its potential role in weight loss.
What is Naltrexone?
Before we dive into how naltrexone can help with weight loss, let’s take a step back and talk about what it is and what it’s traditionally used for. Naltrexone is an FDA-approved medication that was first introduced in the 1980s as a treatment for opioid addiction. It works by blocking the opioid receptors in the brain, which helps to reduce cravings and prevent relapse in people who are trying to overcome addiction.
In the 1990s, naltrexone was also approved for the treatment of alcoholism, as it was found to help reduce cravings and the risk of relapse in people who were trying to quit drinking. Today, naltrexone is still widely used for these purposes, but researchers have been exploring its potential benefits for other conditions, including weight loss.
How Does Naltrexone Affect Weight Loss?
So, how does a medication that was originally designed to treat addiction and alcoholism end up being linked to weight loss? The answer lies in the way that naltrexone affects the brain’s opioid system.
When we eat, our brains release endorphins, which are natural opioids that give us a feeling of pleasure and satisfaction. In people who struggle with overeating or obesity, this system can become imbalanced, leading to overproduction of endorphins and an increased desire for high-calorie, high-fat foods.
Naltrexone works by blocking the opioid receptors in the brain, which reduces the release of endorphins and diminishes the pleasurable feelings associated with eating. This can lead to a decrease in appetite and an increase in feelings of fullness and satisfaction, making it easier to stick to a healthy diet and lose weight.
In addition, naltrexone has been shown to affect the body’s metabolism, increasing the breakdown of fat and reducing the storage of fat in the body. This can lead to increased weight loss, particularly in people who have struggled with obesity or weight gain.
The Science Behind Naltrexone and Weight Loss
Numerous studies have been conducted to explore the link between naltrexone and weight loss, and the results are promising. In one study published in the Journal of the American Medical Association, researchers found that obese patients who took naltrexone in combination with a low-calorie diet lost significantly more weight than those who took a placebo.
Another study published in the International Journal of Obesity found that naltrexone reduced body fat by an average of 10% in patients who took the medication for six months. And in a review of 14 studies on the topic, researchers concluded that naltrexone was associated with significant weight loss and improved body composition.
Is Naltrexone a Miracle Solution for Weight Loss?
While the research surrounding naltrexone and weight loss is certainly promising, it’s important to note that this medication is not a magic bullet for weight loss. Naltrexone is not a replacement for a healthy diet and regular exercise, and it’s not a solution for people who are looking for a quick fix.
In fact, naltrexone is typically only prescribed for weight loss in conjunction with a comprehensive weight loss program that includes dietary changes and regular exercise. This is because the medication is designed to support and enhance the effects of a healthy lifestyle, rather than replace it.
Additionally, naltrexone can have side effects, including nausea, headaches, and dizziness, particularly when first starting the medication. And, like any medication, it may not be suitable for everyone, particularly those with certain medical conditions or who are taking certain medications.
Who Can Benefit from Naltrexone for Weight Loss?
So, who can benefit from naltrexone for weight loss? Generally, this medication is prescribed for people who are significantly overweight or obese, and who have tried other weight loss methods without success.
Ideal candidates for naltrexone may include:
- Those with a body mass index (BMI) of 30 or higher
- Those who have tried other weight loss medications or programs without success
- Those who are struggling with food addiction or binge eating
- Those who are motivated to make lifestyle changes, including dietary changes and regular exercise
How to Get Started with Naltrexone for Weight Loss

What is Naltrexone and how does it work for weight loss?
Naltrexone is a medication that was originally developed to treat opioid addiction, but recent studies have shown that it can also be an effective tool for weight loss. It works by blocking the opioid receptors in the brain, which can help to reduce cravings for unhealthy foods and increase feelings of fullness and satiety.
At a low dose, Naltrexone has been shown to have a profound impact on appetite and metabolism, making it an attractive option for those struggling with weight loss. By reducing the body’s ability to respond to opioid signals, Naltrexone can help to decrease hunger and increase the body’s ability to burn fat, leading to significant weight loss results.
How does Naltrexone compare to other weight loss medications?
Naltrexone is unique in that it targets the brain’s reward centers, which can help to reduce cravings for unhealthy foods and increase motivation to make healthier choices. Unlike other weight loss medications that focus solely on suppressing appetite or-blocking fat absorption, Naltrexone takes a more holistic approach to weight loss. This makes it an attractive option for those who have tried other medications without success.
In addition, Naltrexone has a strong safety profile and few side effects, making it a more appealing option for those who are concerned about the potential risks associated with other weight loss medications. With its novel mechanism of action and strong efficacy, Naltrexone is an exciting development in the field of weight loss medications.
How do I take Naltrexone for weight loss?
Naltrexone is typically taken at a low dose of 3-4.5mg per day, which is significantly lower than the dose used to treat opioid addiction. It is usually taken orally, once or twice per day, and can be combined with other weight loss strategies such as diet and exercise.
It’s important to note that Naltrexone should only be taken under the guidance of a healthcare professional, as it can interact with other medications and have side effects in rare cases. Your healthcare provider will work with you to determine the appropriate dosage and ensure that it is safe for you to take.
What are the potential side effects of Naltrexone for weight loss?
The most common side effects of Naltrexone for weight loss are mild and temporary, and may include headaches, nausea, and dizziness. In rare cases, Naltrexone can cause more serious side effects such as liver damage or allergic reactions, but these are extremely rare when taken at low doses for weight loss.
It’s also possible to experience withdrawal symptoms when stopping Naltrexone, which can include headaches, anxiety, and insomnia. However, these symptoms are typically mild and short-lived, and can be managed with the guidance of a healthcare professional.
How long does it take to see results with Naltrexone for weight loss?
Results with Naltrexone for weight loss can vary, but many people start to see significant weight loss within the first few weeks of taking the medication. In clinical trials, participants typically saw the greatest weight loss results within the first 12-16 weeks, with continued weight loss over time.
It’s important to remember that Naltrexone is just one part of a comprehensive weight loss plan, and that combining it with a healthy diet and regular exercise can help to accelerate and maintain weight loss results. With patience and dedication, many people are able to achieve and maintain significant weight loss with Naltrexone.
Can I take Naltrexone with other medications for weight loss?
Naltrexone can be combined with other weight loss medications, such as phentermine or topiramate, to enhance its effects. However, it’s important to do so under the guidance of a healthcare professional, as combining medications can increase the risk of side effects.
In some cases, Naltrexone may also be combined with other medications that target different biological pathways, such as GLP-1 receptor agonists or SGLT-2 inhibitors, to create a more comprehensive weight loss plan. Your healthcare provider will work with you to determine the most effective and safe combination of medications to help you reach your weight loss goals.
Is Naltrexone approved by the FDA for weight loss?
Naltrexone is not currently approved by the FDA for weight loss, as it is primarily marketed for the treatment of opioid addiction. However, many healthcare providers are using it off-label for weight loss, based on the growing body of evidence supporting its safety and efficacy.
While FDA approval would provide additional reassurance, many people have already seen significant weight loss results with Naltrexone, and it is widely recognized as a promising new tool in the fight against obesity. As more research emerges, it’s possible that Naltrexone will become an approved treatment option for weight loss in the future.
