Leptin is a hormone (or chemical messenger) made in fat tissue that performs an essential role in regulating our appetite and metabolism by sending signals to a receptor in our brains. Our brains then interpret the signals as feelings of fullness (also known as satiety). This makes you stop eating and signals your body to burn more calories.

For folks with leptin resistance, the body makes loads of leptin, but the brain doesn’t reply to these leptin signals, so they don’t really feel full or burn the energy they have. Instead, they continue to really feel hungry despite having eaten. The body can’t sense signals that inform it to extend metabolism and burn off energy, in order that they eat more without burning more.

The balance of calories going out and in (energy balance) is uneven, and the surplus calories make fat cells (adipocytes) grow. These fat cells make more leptin, so you usually wind up with a high leptin level (hyperleptinemia) however no way on your body to use it.

Leptin resistance symptoms

Leptin resistance causes many different signs and symptoms, including:

Obesity: Since folks with leptin resistance don’t feel full after eating and don’t burn the calories they take in, they normally experience weight achieve and obesity. This could begin as early as childhood (Lustig, 2006).

Belly fat: People who are immune to leptin could specifically have more stomach fats (additionally called stomach or visceral fat) instead of fats stores distributed evenly around the body (Ma, 2002). That’s significant because visceral fat is linked to an elevated risk of additional diseases like diabetes, coronary heart illness, and more.

Fatigue: People with high leptin levels and leptin resistance often really feel excessively tired and fatigued (Stringer, 2013). Folks with leptin resistance could also be less physically active because the brain doesn’t respond to the signals telling it to burn calories (Lustig, 2006).

Pain issues: The high levels of leptin in individuals with leptin resistance might make an individual more sensitive to pain or more prone to growing chronic pain issues like fibromyalgia (Younger, 2016).

«Junk food» cravings: Leptin resistance and elevated leptin levels can make you more likely to crave high-fat «junk foods» and sweets (Reichelt, 2015; Macedo, 2014).

What causes leptin resistance?

While researchers aren’t completely sure what the supply of leptin resistance is for everyone, a couple of things likely contribute.

Leptin resistance may be caused by a disruption to a part of the brain called the hypothalamus. Leptin works by sending signals to the hypothalamus, and studies suggest that people with obesity have elevated inflammation in this space, which may disrupt the hormone’s communication with the brain (Thaler, 2012).

Fatty acids may also cause leptin resistance. Fatty acids are a part of fats found in lots of foods. A few of them are essential for nutrition, but some of the fatty acids present in saturated fats (like palmitate) can block the brain’s response to leptin (Kleinridders, 2009).

Diagnosing leptin resistance

It may be difficult to diagnose leptin resistance since there are not any customary criteria for a diagnosis. Healthcare providers normally make the prognosis based mostly on signs and symptoms. They may additionally get a blood test to check your leptin level, however they usually don’t make the prognosis based just on the test (Gruzdeva, 2019).

Unlike conditions like diabetes or coronary heart disease, leptin resistance is more of an underlying condition that contributes to obesity quite than a distinct prognosis on its own. That signifies that while some people with obesity might have leptin resistance, they could never be tested or handled specifically for the condition.

Instead, lifestyle changes and treatments used to help with obesity and associated medical conditions will be probably the most likely therapies provided to people who could have undermendacity leptin resistance, even if it’s by no means explicitly diagnosed.

Leptin resistance treatment

People with leptin resistance often have obesity and could also be at risk for conditions like high cholesterol, coronary heart disease (cardiovascular illness), and type 2 diabetes. Since leptin decreases your appetite and helps burn calories, would a leptin complement be a superb treatment for these people?

It turns out that it’s not. Studies have shown that giving folks leptin doesn’t assist deal with obesity caused by leptin resistance (Paz-Filho, 2011). Individuals with leptin resistance and obesity have more body fat, so that they normally have very high leptin levels (since body fats produces leptin), and adding more isn’t useful (Maffei, 1995). That’s because the problem is with the receptors for leptin.

The only folks with obesity who benefit from leptin treatment are those that have a condition called congenital leptin deficiency (CLD), in which they produce almost no leptin at all (Sáinz, 2015). They haven’t any leptin, however they are sensitive to its effects. After they’re treated with leptin, they often have lower ldl cholesterol and blood sugar (glucose) and are able to drop some pounds (Paz-Filho, 2011).

There’s at present no particular treatment for treating leptin resistance, but there are dietary adjustments and lifestyle modifications that will help handle it.
