Studies have shown that insulin resistance can lead to weight gain in the body. Naltrexone can reduce insulin resistance in your body and thereby reduce the risk of weight gain.
  • Consumption of Naltrexone can enhance the production of growth hormones in your body: Studies have proved that the consumption of Naltrexone in shorter amounts can enhance the production of growth hormones in your body.  These hormones can accelerate the process of lipolysis, which means converting fat into energy. Thereby the usage of Naltrexone can positively affect the process of weight loss in your body.
  • Naltrexone can keep control of your appetite levels:  Consistent usage of Naltrexone can have a modulating effect on your appetite.

  • It can reduce inflammation in your body:  In fact, Naltrexone is an excellent anti-inflammatory agent that can reduce inflammation in your body. Inflammation can have a considerable effect on your weight gain as it can increase insulin resistance and leptin levels. Along with that, if your body has some kind of inflammation you tend to have an increased level of appetite which can also lead to a severe case of weight gain.
  • Naltrexone can enhance your sleep quality: Low Dose Naltrexone (LDN) has a considerable effect in reducing your neurological pain and thereby aiding in sound sleep. As you know, sleep is a crucial component in weight loss. Lack of quality sleep is linked with inflammation and other chronic conditions which can lead to weight gain. When you start consuming LDN you get some quality sleep and thereby you lose weight.
  • Naltrexone can increase thyroid hormone production:  Consumption of LDN is linked with an increase in thyroid hormone production in your body. Studies have proved that the higher the thyroid hormones, the chances of weight loss is even greater. Naltrexone can deal with the condition of hypothyroidism and weight gain and reverse the effects of these chronic conditions in your body.
