A lack of shut-eye will disrupt all your hormones, including leptin. That makes sense because there’s not much you can do about being hungry when you’re asleep in the middle of the night.īut sleep still plays a big part in leptin levels. Leptin levels tend to peak between midnight and dawn, making you less hungry. That means they are active during the day and sleep at night.

Most humans have a “diurnal” rhythm to their day. There are deep seated social and psychological issues that can change the cycle of hunger and satiety, she says: “Does the food look good to me? Do I really want to eat it? Do I have a circle of friends sitting here … so maybe I’ll eat a little more?”Įven your regular lifestyle habits of diet, exercise, and stress management can play a part. Hormones aren’t the only things that affect it. Hunger is complex, says Rutuja Patel, DO, medical director for medical weight loss at the Northwestern Medicine Central DuPage Hospital. “That’s another way of telling the body I’m in a relatively low-energy state because I haven’t eaten for 10 hours.” “If someone fasts for 8 to 10 hours, your total body fat won’t change much during that time, but the leptin will drop,” Yale’s Mehal says. Simply fasting for several hours can cause your leptin levels to drop.

They just get smaller.īut it’s not always about body fat. Though, keep in mind that you never lose fat cells. That’s in part because typically your body automatically makes less leptin when you lose fat mass. If you’ve ever been on a diet, you might have noticed that you get hungrier when you cut your calories or start to lose weight. More specifically, high leptin levels tell your brain “your fat cells are full,” which makes you less hungry. When everything works the right way, it helps you maintain a healthy weight by balancing the amount of food you eat with how much fat you have. Low levels of leptin, on the other hand, are part of the complex hormonal dance that makes you feel more hungry. That “stuff,” Mehal says, could be any number of things from exercise to growth in puberty to conceiving a child. “When the brain says, ‘Oh, we have leptin!’ That tells me that we have fat, which tells me that we have energy reserves to do stuff,” says Wajahat Mehal, MD, PhD, director of the Yale Metabolic Health and Weight Loss Program. It circulates in your bloodstream and travels to your brain.Īnd that’s where leptin delivers a very important message: We have enough fuel! But your stomach releases some when you eat. It also plays a role in how your body turns fat into energy. You may hear it called a satiety hormone.
