Believe it or not, leptin wasn't discovered until 1994 and it pays a MAJOR role in our health and ability to stay lean Leptin is a hormone made by your fat cells that is responsible for reducing hunger
It is also known as your "satiety hormone," or "the master hormone of body fat regulation" When you eat a meal, leptin gets released by your fat cells and travels to your brain It basically signals to your brain that your body is full and needs no more food It is an important hormone that aids in appetite control In obesity, there's a lot of body fat in fat cells
Fat cells release leptin according to their size, so the more fat you have, the larger the leptin levels Increased leptin levels from their full fat stores should be telling the brain to stop the consumption of food The problem with obesity is that the leptin signal isn't working properly There's a ton of leptin floating around, but the brain is becoming unresponsive to the signal, and is tricked into thinking there is too little leptin present Your brain has essentially become numb to the "stop eating" warning
This condition is known as leptin resistance We've already talked about the hormone insulin and how we've become resistant to it…Well, the hormone leptin is no different Leptin resistance develops in response to chronically elevated leptin levels, so the brain eventually stops responding to the large amounts of leptin released, and you don't get the signal to stop eating It mistakenly thinks the body is starving, even though it has more than enough fat stored First, our brain signals our body to eat more in order to not starve to death
Second, it reduces our metabolism because the brain thinks we need to conserve energy, making us burn fewer calories, and making us feel sluggish and lazy The good news, is you can reset your leptin sensitivity! If you are overweight or obese, most likely you are leptin resistant This is the case especially if you have excess fat in the midsection A big key to preventing and reversing leptin resistance is following a diet that keeps inflammation and triglycerides low There are several things that you can do right now to increase your leptin sensitivity
They are to avoid processed food, consume healthy fats, exercise, sleep, reduce your carbohydrate intake, and have a healthy protein intake Did you notice anything about these recommendations? Yep these are the exact same guidelines for anyone just wanting to be healthy…Regardless of their circumstance Eating whole foods, exercising and sleeping well are all lifestyle factors that contribute to health and wellness for life Where does intermittent fasting come into play here? Recent research in the International Journal of Obesity found that intermittent fasting was effective at reducing leptin hormones and improving leptin resistance In addition, it fight inflammation and lowers triglycerides
This is yet another reason to be a "sensitive" person!
