ScienceWeightLoss_wb3[i-1].body = "Scientists have isolated the short-term hormone PYY3-36, which is secreted by cells lining the intestines after eating. The so-called “third helping hormone” sends signals to the feeding circuits in the brain that convey a sense of satiety, which reduces the urge to eat. In a small experiment, people who received an infusion of the hormone ate one-third less over the next 24 hours than those who received a placebo. Researchers think a medication based on boosting levels of the hormone might reduce overeating and between-meal snacking. ";

It has been found to stimulate hunger in rats and make people so ravenous that they eat nearly a third more food than usual. Ghrelin has also been found to rise in the bloodstream after dieters lose lots of weight, possibly explaining why it’s so hard to keep weight off long-term. The hormone is considered a potential new treatment for both obese patients and those with conditions that cause a dangerous loss of appetite, such as cancer.";

It’s supposed to signal the brain to stop eating, but the signal does not get through in some overweight people. At one point a few years ago, doctors thought leptin could be used as a breakthrough obesity drug. So far, it has not lived up to its promise, but a recent study showed that tiny doses of leptin taken after weight loss could help people keep weight off. ";
