Leptin Serum / Obesity Hormone
Also Known As
Test Parameters Included
- The amount of leptin in the blood is directly proportional to the amount of body fat.
- In a healthy system, high fat leads to high leptin, which reduces appetite.
- However, in many cases of obesity, the brain stops "hearing" the leptin signal.
- This is known as Leptin Resistance, where the body stays in a state of constant hunger despite having high energy stores.

Frequently Asked Questions
Why is Leptin called the "Satiety Hormone"?
Because its primary job is to tell your brain you are "full" and have enough stored energy to stop eating.
If I am overweight, shouldn't my Leptin be high?
Yes, it usually is. The problem in obesity is typically not a lack of leptin, but rather the brain ignoring the signal (Leptin Resistance).
Why does the report take 8 days?
ELISA testing for specialized hormones like Leptin is often performed in batches or at specialized reference labs to ensure the highest accuracy.
Can I take Leptin as a supplement?
Oral leptin supplements are generally ineffective because leptin is a protein that is digested in the stomach before it can reach the blood.
Does sleep affect Leptin?
Yes! Sleep deprivation significantly lowers leptin and raises ghrelin (the hunger hormone), which is why you crave junk food when tired.
Why do women have higher Leptin than men?
Women generally have a higher percentage of body fat and different hormonal structures that naturally maintain higher leptin levels.
What is the "Starvation Signal"?
When you diet strictly and lose fat, leptin levels drop. This tells the brain you are "starving," which slows down your metabolism to save energy.
Can stress increase Leptin?
Chronic stress and high cortisol can contribute to leptin resistance, making it harder to manage appetite.
Do I need to fast for this test?
Yes. A 12-hour fast is required for a reliable result.
Can this test diagnose why my child is gaining weight rapidly?
It can help identify rare genetic leptin deficiencies, which are treatable with leptin replacement therapy.
Does exercise improve Leptin sensitivity?
Yes. Regular physical activity is one of the best ways to help the brain start "responding" to leptin again.
Is Leptin related to Insulin?
Yes. They are "partner hormones." High insulin (insulin resistance) often leads to high leptin (leptin resistance).
What is the difference between Leptin and Ghrelin?
Leptin is the "Stop Eating" signal (long-term), and Ghrelin is the "Start Eating" signal (short-term).
Does inflammation affect the result?
Yes. Chronic inflammation can interfere with leptin's ability to cross the blood-brain barrier.
How can I lower my Leptin naturally?
By reducing systemic inflammation, improving sleep, and lowering body fat through a consistent, healthy lifestyle.
