However, modern obesity research disagrees… and scientists are increasingly pointing their fingers at a hormone called leptin (1). Being resistant to this hormone’s effects (called leptin resistance) is now believed to be the leading driver of fat gain in humans (2).
Leptin’s primary target is in the brain, particularly an area called the hypothalamus.
Leptin is supposed to tell the brain that we have enough fat stored, that we don’t need to eat, and that we can burn calories at a normal rate (4).
The leptin system evolved to keep us from starving or overeating, both of which would have made us less likely to survive in the natural environment. Leptin is carried by the bloodstream and into the brain, where it sends a signal to the hypothalamus… the brain area that controls when and how much we eat (8).
Because fat cells produce leptin in proportion to their size, obese people also have very high levels of leptin (10).
When the brain doesn’t receive the leptin signal, it erroneously thinks that the body is starving, even though it has more than enough energy stored. In this way… eating more and exercising less is not the cause of weight gain, it is the consequence of leptin resistance, a hormonal defect (16).
For the great majority of people, trying to exert cognitive inhibition (willpower) over the leptin-driven starvation signal is next to impossible.
There are many possible reasons for this, but the research is showing that leptin may have a lot to do with it (17, 18).
Losing weight reduces fat mass, which leads to a significant reduction in leptin levels, but the brain doesn’t necessarily reverse its leptin resistance. When leptin goes down, this leads to hunger, increased appetite, reduced motivation to exercise and decreased amount of calories burned at rest (19, 20). Basically, the reduced leptin makes the brain think it is starving… so it initiates all sorts of powerful mechanisms to regain that lost body fat, erroneously thinking that it is protecting us from starvation. Inflammation: Inflammatory signalling in the hypothalamus is likely an important cause of leptin resistance in both animals and humans.
Free Fatty Acids: Having elevated free fatty acids in the bloodstream may increase fat metabolites in the brain and interfere with leptin signalling. Having high leptin: Having elevated levels of leptin in the first place seems to cause leptin resistance. Pretty much all of these factors are increased in obesity… so this may form a vicious cycle where people get fatter and increasingly more leptin resistant over time. Bottom Line: Potential causes of leptin resistance include inflammation, elevated free fatty acids and high leptin levels.

If you have a lot of body fat, especially in the belly area, then you are almost certainly leptin resistant. A key to preventing (or reversing) leptin resistance, is reducing diet-induced inflammation. Lower your triglycerides: Having high blood triglycerides can prevent the transport of leptin from blood and into the brain (27). Although the causes of obesity are complicated and diverse, leptin resistance is the main reason people gain weight and have such a hard time losing it. The most groundbreaking discovery for me, though, was the discussed difference in leptin sensitivity between men and women.
Apparently, leptin doesn’t just control the release of body fat; it also plays an integral role in maintaining your metabolism, responding to food input and exercise output, etc.
A resounding NO from the author; we women just have to take our leptin levels into consideration in order to prevent metabolism crashes, hunger, and cravings. The VF has provided me with a clear path toward feeling good about myself: eating less is simple when you have guidelines instead of absolute rigidity, when you know you won’t have to face massive leptin drops and associated misery, and when you have a caring community who’ve been there supporting you the whole way. High levels of Leptin and the accompanying leptin resistance can also decrease fertility, age you more quickly and contribute to obesity. In other words, if you want to make lasting health changes or lose weight and keep it off, you have to fix your leptin. Leptin is the satiety hormone produced by fat cells, so it would seem logical that those with more fat cells would produce more Leptin, which would signal the body to eat less food and weight would normalize. Eat (or take) more Omega-3s (fish, grassfed meats, chia seeds) and minimize your Omega-6 consumption (vegetable oils, conventional meats, grains, etc) to get lower inflammation and help support healthy leptin levels. Typically, if you are overweight, it is pretty certain you are Leptin resistant, or if you have sleep troubles or fatigue in the afternoon.
Yes, there is a blood test that can show the Leptin level and if it’s too high, like mine is. Stephan Guyenet, an obesity researcher and blogger, explains everything you need to know about leptin and how it is implicated in obesity. Lots of leptin tells the brain that we have plenty of fat stored, while low levels of leptin tell the brain that fat stores are low and that we are at risk of starvation (9). There are many reason for that, one of them may be an improvement in leptin sensitivity (29). I had heard of leptin mentioned vaguely before: the hormone that regulates fat loss, that’s being studied in multiple weight-loss drug clinical trials, etc. Now, because women have a higher healthy body fat percentage than men, we also naturally have almost twice as much leptin in our bodies.

Because we women a) have more leptin in our bodies naturally, and b) are insensitive to leptin as compared to men, our metabolisms seesaw all over the place on calorie-restricted diets (leading to the aforementioned crashes), while men’s bodies are able to maintain a more or less steady metabolism since their naturally low leptin levels tend not to vary as much as ours do. Even better, you can start out with at-home exercises that use your own body weight as resistance (this is what I’m doing to start, anyway!).
Many people these days are Leptin resistant and there are many health problems tied to this problem.
If you’re trying to lose weight or improve a health problem, chances are you have Leptin resistance.
This leptin resistance is sensed as starvation, so multiple mechanisms are activated to increase fat stores, rather than burn excess fat stores.
I had absolutely no idea how critical leptin—and your body’s sensitivity to leptin—is before reading this guide, though!
Based on this simple fact, the author (who, yes, is a man, but one who understands and cares about women’s wellbeing!) notes that, since leptin plays a crucial role in both diet and exercise, a diet and exercise program for women should be tailored toward our extra leptin. By increasing our sensitivity to leptin—mainly through a strategic nutrition and exercise plan.
Leptin is secreted by adipose (fat) tissue, so the more overweight a person is, typically, the higher his leptin levels. High leptin levels have been tied to high blood pressure, obesity, heart disease and stroke, as well as blood sugar related problems. If you can’t seem to stick to health changes, chances are you have Leptin resistance.
Leptin resistance and its related problems are a complex problem involving the endocrine system and reversing them requires more than simple calorie restriction or will power. Jack Kruse (a neurosurgeon) and Stephan Guyenet (an obesity researcher) have both written in depth about the causes of Leptin imbalance and ways to reverse it.
Instead of maintaining a calorie-restricted diet constantly, “eat-up days” (very different than the “cheat days” accompanying most diet plans!) once or twice a week allow our leptin levels to settle rather than crash.
In addition, male test subjects are much more common than females (this is true even of lab rats), meaning most clinical results that are interpreted as an effect on people should actually be interpreted as an effect on men.
I also had a regular Executive Panel blood workup done at the same time, with faster results, but it didn’t test for Leptin. I’m thankful to know now that working on my Leptin level and Leptin resistance issues is going to make a difference for my health.
