Just recently, it was discovered that the hypothalamus produces a hunger hormone, dubbed “orexin” after orexis, the Greek word for hunger. When the brain senses a need to eat, such as after a drop in blood sugar, it starts producing more orexin.

Lots of factors trigger hunger or lack of it: disease, emotions, weather (cold increases hunger, hot decreases it), the composition of your diet (a well-balanced diet keeps hunger pangs in check), to name just a few.

Hunger is different from appetite. The best way to understand the difference is this: With hunger, you eat in response to physical sensations (like hunger pangs). With appetite, you eat in response to cravings for certain foods cravings based on foods you grew up loving, social situations such as parties or holidays, or mood states such as depression or anxiety.

Additionally, you may crave certain foods for physiological reasons. For example, a woman may hanker for chocolate during her period a craving probably triggered by hormonal fluctuations, since hormones play a role in regulating appetite. Thus, appetite is influenced by many social, cultural, psychological, and physiological factors.

Appetite, like hunger, is controlled by the hypothalamus. In fact, the hypothalamus can switch appetite off and on, in much the way a thermostat regulates room temperature. Appetite and hunger often accompany one another, increasing or decreasing our desire and need for food.

The search for safe and effective appetite-killing drugs continues. Some success has been achieved, but not without great cost to health.

Fortunately, though, effective alternatives are available. There are many natural appetite suppressants that appear to curb overeating safely.

Undereating. Believe it or not, chronic calorie-cutting can make you fat! Overly restricting your calories below 1,200 if you’re a woman, or below 1,600 if you’re a man, can slow your metabolism the body’s food-to-fuel process. This results in something called the “starvation adaptation response.” Without adequate calories, your body is tricked into thinking its starving. At www.ShopPharmacyCounter.com we have huge veriety of worlds best weight loss supplements to help increase metabolism, promote appetite suppression, energy and rapid weight loss. We offer brands like Fastin, Phentramin D, eca stack and other very effective ephedra diet supplements. As a built-in survival mechanism, a special fat storage enzyme (lipoprotein lipase) mounted on the surface of fat cells in the body goes to work, signaling your body to stockpile dietary fat rather than burn it for energy. You can actually gain body fat on a diet of less than 1,200 calories a day, not to mention skimp on important nutrients. That’s why it’s both unwise and unhealthy to cut calories drastically. Several natural weight-loss supplements let you eat ample calories, without restrictive dieting, and still lose appreciable amounts of body fat.

Underexercising. Are you physically inactive? Being a couch potato is a major contributor to obesity even more than overeating is, say some health experts. Generally, people are now eating smaller amounts of fattening foods, but paradoxically, obesity is on the rise. Lack of physical activity may be the most reasonable explanation. If you’re not exercising, it could be due to lack of energy. Good news: There are a couple of natural weight-loss supplements that may help energize you for exercise.

Genetics. If one of your parents was obese, you have a 60 percent chance of being plump, too; if both were obese, your chances rise to 90 percent. No one knows for sure why this is so, but researchers have discovered a gene in humans that they’ve dubbed the ob gene.

This gene manufactures a hormone called leptin. Leptin is secreted by fat tissue and released into the bloodstream. It then travels to the brain. Its job there is to help the body regulate its fat stores by curbing appetite and stimulating metabolism. Scientists speculate that obese people may be “resistant” to the effects of leptin. In other words, their brain cells are unresponsive to leptin in much the same way body cells of diabetics are unresponsive to insulin. Research on a leptin-based drug has produced mixed results. With diet and exercise, some people lost weight, others lost no weight, and some even got fatter. There are, however, several natural weight-loss substances that do a great job of suppressing the appetite and stimulating the metabolism. These may help you, even if it looks like heredity is not on your side.

Thermogenesis. One theory of obesity holds that plump people may have a slower rate of “thermogenesis” the body’s natural ability to generate heat as a result of breaking down food for energy. The body tissue that specializes in converting energy to heat is brown fat, which is located deep within the body and insulates internal organs. By contrast, white fat cells found in the muscles and under the skin tend to store energy.

Scientists have theorized that people who have less than a normal amount of brown fat tend to store more white fat. New research points to the fact that fat cells, both brown and white, of obese people generate less heat which could result in more calories being stored as bulges. Some of the natural weight-loss supplements now on the market are believed to stimulate the thermogenic capability of brown fat and thus burn more stored fat.
