Originally developed to treat addiction, this drug is now being explored for its potential to help patients shed excess weight when used in low doses or combined with other medications. But how exactly does it work, and is it safe?

In this article, we’ll break down everything you need to know about naltrexone for weight loss, from how it functions in the body to what results you can realistically expect. We will respond to your most urgent inquiries in an easy and straightforward manner.

Key Points:

• Low doses of naltrexone are being employed in order to control cravings and appetite.
• It can be used together with other drugs to achieve more weight loss.
• The answer to this is the appropriate use, medical recommendation, and lifestyle modification.

What is the manner by which Naltrexone Aids In Shedding Some Pounds?

Naltrexone initially served as a treatment of alcohol and opioid addiction. However, scientists discovered that it has something to do with other parts of the brain that control cravings and hunger. In low doses and in a modified formulation called low-dose naltrexone (LDN), it can be used to lessen the desire to overeat or eat unhealthy snacks.

Naltrexone acts on receptors in your brain that makes up the opioid. These receptors are associated with the pleasure that one obtains in consuming food, especially the high-sugar or high-fat food. Naltrexone can reduce the reward effect you feel when you eat these foods by blocking these receptors, and in turn, some individuals may eat less in general.

Example:
Suppose there is somebody who does snack on chips nightly. Once on naltrexone, they might feel that the cravings are no longer overwhelming and even when they consume the chips, it does not give a great taste.

This mechanism also explains why naltrexone for weight loss is often combined with bupropion, another medication that targets the brain’s reward system. Together (used in a drug called Contrave), the two drugs are approved by the FDA as weight-loss drugs.
