Leptin Vs Ghrelin

These three hormones, orexin, gherlin and leptin, act on your brain to normalize your drive for food. In this way your body responds appropriately with hunger for breakfast. Breakfast is the combination of two words, “break” and “fast”.

While ghrelin is an appetite-stimulating peptide, leptin is an appetite-suppressing one. Ghrelin, secreted from the stomach, particularly influences the metabolism of fat tissue by promoting its storage during hard times. Leptin and ghrelin function interdependently in healthy humans.

The world leptin means “full” in Greek. Leptin is produced in the fat cells and released in the brain. Leptin gives us a feeling of satisfaction. While ghrelin enhances appetite, leptin acts as a satiety signal to diminish it. …show more content…
Ghrelin also regulates water and fluid intake, so if you drink a glass of water when you are hungry, ghrelin signals can be satisfied and weakened slightly. This provides a simple way to control your hunger. One glass of water before every meal decreases the amount you will eat by at least 8 ounces and suppresses ghrelin.

Slim women have learned to lower their ghrelin level, but these amounts rise immediately with diet-induced weight loss. Yes, thin people do not diet for that very reason. If they did, they would start to gain weight. The more a person diets, the hungrier they get. It is almost as if semi-starvation triggers gherlin to increase. This may be part of the reason that we regain weight lost by dieting and then some. The secret is to stop dieting.

In addition to stimulating GH secretion, ghrelin affects your stomach acid secretion and how smoothly the food moves along your gut. This function called intestinal motility is damaged in both constipation and diarrhea. A condition called “irritable bowel syndrome” may be nothing more than a ghrelin imbalance. More research is needed.

Ghrelin induces other metabolic actions such as spikes in blood sugar, called the hyperglycemic effect. Therefore modified fasting, which decreases ghrelin secretion and increases leptin, may provide an effective technique for treating …show more content…
Leptin also suppresses a liver enzyme that converts unsaturated fats into monounsaturated fats burning fat as energy.

The balance and communication between these two systems sets a limit on food intake and growth hormone release. An impairment of this equilibrium results in disorders of feeding behavior such as weight gain or weight loss (cachexia). Neither is very desirable. If leptin is so useful, what about getting leptin shots?

Unfortunately, doctors can’t give someone a leptin shot to make them stop eating, since in severely obese people, unlike mice, hormones seem to work differently. In genetically altered mice, without the receptor for leptin, injecting leptin will only partially correct the defect reversing their obesity. This indicates that other factors play supporting roles. Leptin corrects insulin resistance, or diabetes, in mice that lack fat tissue (a condition called lipodystrophy). Scientists have tried leptin replacement therapy in lipodystrophic humans with good
