Ghrelin News and Research

RSS

Ghrelin is a hormone produced mainly by P/D1 cells lining the fundus of the human stomach and epsilon cells of the pancreas that stimulates appetite. Ghrelin levels increase before meals and decrease after meals. It is considered the counterpart of the hormone leptin, produced by adipose tissue, which induces satiation when present at higher levels. Ghrelin is also produced in the hypothalamic arcuate nucleus where it stimulates the secretion of growth hormone from the anterior pituitary gland.

Dietary protein reduces hunger and increases fullness in obese men

A new study demonstrates that higher-protein meals improve perceived appetite and satiety in overweight and obese men during weight loss. According to the research, published in Obesity, higher-protein intake led to greater satiety throughout the day as well as reductions in both late-night and morning appetite compared to a normal protein diet.

Despite the contribution this behavior makes to the current obesity epidemic, little is known about the molecules and nervous system circuits that control it. Insight into this could provide new targets for the development of therapeutics to curb this potentially detrimental behavior.

Hunger hormone likely to cause stress-linked complex eating behaviors

We are one step closer to deciphering why some stressed people indulge in chocolate, mashed potatoes, ice cream and other high-calorie, high-fat comfort foods. UT Southwestern Medical Center-led findings, in a mouse study, suggest that ghrelin - the so-called "hunger hormone" - is involved in triggering this reaction to high stress situations.

Food, drugs of abuse engage same brain systems, show studies

New animal research helps explain why some eat without hunger or to excess. The studies explore the biological effects of poor eating habits, showing that high-fat diets cause lasting brain changes that may impair healthy eating. Additional studies show that food and drugs of abuse engage many of the same brain systems. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.
