Since leptin is a hormone your body makes and not a nutrient (like vitamin C or protein), no foods contain leptin. Since leptin is a relatively new discovery, scientists are still working to learn more about it, including how it affects obesity and weight loss.
Exercise Regularly
Exercise increases leptin levels by increasing sympathetic nerve activity and improving insulin sensitivity. It also leads to changes in adipocytes, the cells that store fat. Adipocytes release more leptin when they are exposed to catecholamines, which are increased during exercise.
Berries Replace sugary foods with fruit in its natural form and also ranked in the leptin-containing food group. Berries like blueberries, raspberries, and strawberries are lower in sugar than some other fruits and can help lower your triglyceride levels.
Vitamin A was positively associated with leptin concentrations (p < 0.05).
Leptin is a hormone produced naturally in the body that helps regulate feelings of satiety (fullness or hunger). Because of this, marketers commonly promote leptin supplements as a weight-loss aid. But these supplements don't actually contain leptin, which means they're unlikely to lead to weight loss.
Unfortunately, there's not much you can do to raise your leptin levels to decrease hunger and appetite, since your leptin levels are directly related to how much adipose tissue your body has.
Congenital leptin deficiency is a condition that causes severe obesity beginning in the first few months of life. Affected individuals are of normal weight at birth, but they are constantly hungry and quickly gain weight.

Leptin Foods to Avoid
Avoiding these foods will help your body re-sensitize to leptin so you feel full when you've eaten enough. Legumes (high in carbs and lectins)–kidney beans, soy products, black beans etc. Vegetable “seed” oils–sunflower oil, canola oil, corn oil, safflower oil etc.
Plasma leptin levels decrease during fasting[8] or energy restriction[9] and increase during refeeding,[10] overfeeding,[11] and surgical stress. [12,13] Insulin, glucocorticoids, serotonin, and estrogen have been reported to stimulate leptin secretion.
Findings from numerous studies indicate that coffee is considered as an important dietary factor related to the elevation of adiponectin level. Coffee may also reduce the concentration of leptin; however, it is still under debate. Coffee is considered as one of the food sources containing several antioxidants.
On the other hand, several studies showed a negative relationship between leptin and coffee consumption. Two cohort studies of 15,551 women and 7397 men of US health professionals found that coffee drinkers of ≥4 cups/day had lower leptin compared with nondrinkers.
Leptin isn't a vitamin or mineral. You can't absorb it from a pill. In fact, “leptin supplements” don't contain any actual leptin. If they did, your stomach would simply digest them before they could have any effect on your body.
The take-away is that your nutritional habits, dietary patterns, and nutrition quality can all have a positive influence on your fat burning hormones. In addition, lifestyle factors like sleep and stress management can also turn on these hormones and help you achieve and maintain your weight loss goals.
Time-Restricted Eating and Fasting
Eating late in the day, especially after 8 pm, has been associated with higher leptin resistance levels, increased hunger, and more weight gain. Some studies suggest that fasting may help reduce inflammation and reset leptin receptors, encouraging weight loss.
Fasting and energy-restricted diets elicit significant reductions in serum leptin concentrations. Increases in adiponectin may also be observed when energy intake is ≤50% of normal requirements, although limited data preclude definitive conclusions on this point.
Fasting helps reduce the inflammation that causes leptin resistance and resets leptin receptors, encouraging weight loss.
It was concluded in the concerned study that there was a positive correlation between zinc and leptin and that this effect of zinc on leptin might be mediated by elevated IL-2 and TNF-α levels.
Fatty acids can also cause leptin resistance. Fatty acids are a component of fats found in many foods. Some of them are essential for nutrition, but some of the fatty acids found in saturated fats (like palmitate) can block the brain's response to leptin (Kleinridders, 2009).
As in mammals, chicken leptin expression is regulated by hormonal and nutritional status. This regulation is tissue-specific and with a high sensitivity in the liver compared to adipose tissue. The blood leptin levels are regulated by the nutritional state with high levels in the fed state compared to the fasted state.
Herbs for Blood Glucose, Insulin, and Leptin Regulation
The herbs Cinnamomum cassia (Chinese cinnamon) and Gymnema sylvestre have been shown to reduce food intake by regulating the appetite through the control of insulin, serum glucose levels, and leptin.
