Hormones are chemicals which act at specific sites in the body, called target tissues, and instigate change at those sites. A hormone that has gained popularity lately is leptin, due mostly to its activity as an "anti-obesity" hormone. Leptin has...
Over the past 20 years, the United States has seen a massive increase in the incidence of obesity, the Centers for Disease Control and Prevention reports. In 2010, not a single state had an obesity prevalence level of less than 20 percent; twelve...
Leptin is a hormone which is released from fat cells and regulates the fat stores in the body. If the body has sufficient amounts of fat, satiety signals will be sent to the hypothalamus, the region of the brain which is responsible for regulating...
Leptin is a hormone that may bridge body composition and appetite. Body composition is determined by many factors. Genetics, or body type, the metabolic rate and the drive to eat are more innate factors. External factors include availability of...
Leptin is a hormone produced primarily by your fat tissue. It plays a key role in controlling appetite and regulating the amount of energy you burn. In addition, leptin is instrumental in immune and reproductive function, and it participates in...
Leptin, a hormone secreted by fat cells, acts on the brain to suppress your appetite. Severely overweight people tend to have higher concentrations of leptin in their blood than people with less body fat. Gaining weight, however, is not the ideal...
Metabolism, appetite, satiety and other factors influence body weight through a complex interplay. Leptin and ghrelin are two hormones with effects that influence body weight. Weight loss and gain, as well as the diagnosis and treatment of...
Leptin, a hormone produced by fat tissue, serves a negative feedback role for management of weight, appetite and other metabolic parameters. Leptin exerts its effects on the hypothalamus, where the brain's appetite control centers are located....
Histamine is a body chemical that is released from mast cells, where it contributes to the immune response against allergies or other body invaders and to increased stomach acid secretion and digestion. In addition to its natural form,...
People on a weight loss plan are rewarded by their efforts as they watch the numbers on the scale decrease. But at some point, the numbers stop dropping. This is called the diet plateau, and it happens to even the most compliant dieter.
Blueberries are one of the healthiest fruits, containing fiber, potassium, B vitamins and vitamin C. Most of the health benefits of blueberries come from potent antioxidants called anthocyanins. Instead of eating fresh blueberries, many people opt...
Leptin is a protein hormone that plays a key role in regulating energy intake from food, appetite and metabolism. At times, leptin levels may become elevated in children. The causes of leptin elevation can differ from patient to patient. Be...
Leptin is a human hormone that plays significant roles in appetite and weight control, metabolism and reproduction. At the same time, leptin is associated with a host of disease states. This hormone is produced by fat cells throughout the body and...
The Cheat to Lose diet is based on the principles of manipulating two hormones related to hunger and metabolism in the human body, leptin and gherlin. Leptin is a hormone that increases metabolic rate. Its concentration drops significantly during...
Leptin is a protein that binds to receptors in your brain and performs several actions that may prove important in treating obesity. It is called the "satisfaction" hormone because it's most noted function is to tell your brain when you've had...
You can't walk into your local pharmacy and buy the hormone leptin. And at this time, you can't ask your doctor for a prescription for it, either. There aren't any current over-the-counter leptin supplements that actually contain leptin in the...
Leptin is a hormone naturally produced by the adipocytes, or fat cells, of the body. Leptin is released in the bloodstream and goes to the hypothalamus in the brain where it reduces feelings of hunger and decreases the appetite. This hormone plays...
When Rockefeller University scientists first introduced leptin to the world in 1994, the thinking was that the newly discovered hormone represented a breakthrough in treating obesity. However, subsequent research showed that excess leptin and...
Your own anecdotal experience may tell you that coffee consumption is related to weight loss. Coffee has been consumed for generations and its affects on energy are well-known. Recent research has helped us to better understand the mechanism that...
Discovered in 1994, the hormone leptin first gained attention as an indicator of the body's energy stores. Your fat cells are the primary producers of leptin; the blood level of the hormone correlates to the amount of fat in your body. In addition...
In the last 20 years, the rate of obesity -- defined as having a body mass index greater than 30 -- has dramatically risen in the U.S., according to the Centers for Disease Control and Prevention. Much of the obesity epidemic is blamed on the...
The American Dietetic Association recommends that pregnant women eat about 300 extra calories each day to fuel their new baby's growth, but many women feel the need to consume far more than the suggested number of calories. Although health experts...
Leptin is famously known as the satisfaction hormone. It's what triggers that sensation of fullness you get after you've eaten. Leptin comes from fat and, when released, it binds with receptors all over your body, but especially in your brain. In...
Your body strives to keep you in a state of energy balance. It wants you to put in and burn off the right amount of calories. Ghrelin and leptin are two hormones that facilitate this process by sending signals to your brain. Ghrelin says, "I'm...
Leptin is a hormone secreted by the body that acts on the hypothalamus of the brain, which controls hunger and body weight. Your body can become resistant to the action of leptin, much like insulin resistance that is seen in persons before...
Your liver is about the size of a football and performs over 500 vital functions in your body. Liver diseases like cirrhosis and hepatitis are potentially life-threatening, prompting patients to turn to alternative medicine and dietary changes to...
People who are obese are at a greater risk for several chronic diseases, which is why researchers around the globe have been searching for ways to prevent and treat the condition. One of the more promising developments is associated with leptin, a...
When leptin was first discovered in 1994 by Rockefeller University scientists, the mainstream media hailed it as a breakthrough in obesity research. In studies, the hormone cracked down on appetite and upped fat burning. Researchers were looking...
Omega-3 fatty acids may help you to lose weight because they regulate appetite. They are found in fish such as salmon, tuna, trout and mackerel. They are also found in other seafood including algae and krill, some plants and nut oils. Talk to your...
