Can leptin supplements help you lose weight?

Leptin is a protein that is mainly formed in the fatty tissue of the body. It can also be secreted from the liver, placenta, and gastric mucosa. Once released, it passes into the blood and acts as a signal to the brain. This is a hormone that is directly involved in the control of satiety , that is, it plays a very important role in weight regulation. For this reason, in recent years, leptin supplements have become very popular: they are said to be able to decrease appetite and facilitate weight loss. However, the efficacy of hormone supplementation is controversial. Find out everything you need to know about leptin, what it is, how it works and it is true that it can help you lose weight.

What is leptin and how does it work?

The hormone was discovered in 1994 and has since been studied for its role in regulating weight and obesity in both animals and humans. Leptin is a hormone produced by fat cells and is primarily related to intake. After eating, she is in charge of warning the brain that you are already satisfied, and consequently you lose your appetite. Similarly, when you eat abundantly, your levels of leptin blood flow remain elevated for longer.

In other words, this hormone communicates to the brain that you have enough stored fat, which reduces your appetite, signals the body to burn calories and prevents you from overeating. Conversely, when levels are low, your brain senses hunger, increases your appetite, and burns calories at a slower rate. This is the reason why it is often called the hunger hormone .

The more leptin, the more weight loss?

It is important to emphasize that all bodies are different, and therefore, the reactions of the hormone in each person are diverse. For example, people with obesity, despite having high levels of leptin, the brain does not recognize the signals that the hormone sends it. This is known as leptin resistance .
This means that even if you have more than enough of the hormone available, your brain doesn't recognize it and thinks you are still hungry. As a result, you keep eating. Plus you not only eat more, it also signals to your brain that you need to save energy, which leads you to burn calories at a slower rate.
In terms of weight loss, more leptin is not necessarily what matters. What really matters is how well your brain interprets the hormone signals. In other words, due to leptin resistance, more leptin is not proportional to weight loss , as this will only depend on each body. Therefore, taking a supplement that increases leptin levels does not necessarily lead to weight loss.
