Most of these treatments are not very effective.A significant result from this research was the development of a bitter plant extract that suppresses appetite — Amarasate.

The extract, from New Zealand grown hops, relases bitter compounds into the duodenum that stimulate an evolutionary defence mechanism (traditionally bitter foods are potentially harmful) to trigger the release of a peptide hormone that sends a 'stop eating' signal to the brain.Calocurb is the trade-marked weight-management supplement using the Amarasate extract. During the gastric phase, the hormone gastrin is secreted by G cells in the stomach in response to the presence of proteins.

Absorption in the stomach is limited, where only small and fat-soluble substances can be absorbed—water , alcohol, aspirin , and certain drugs . Four important hormones and their effects on target cells follow:Stimulation of gastric juice (especially HCl) secretion by gastric glands.Stimulation of smooth muscle contraction in the stomach, small intestine, and large intestine, which increases gastric and intestinal motility.Relaxation of the pyloric sphincter, which promotes gastric emptying into the small intestine.Stimulation of bicarbonate secretion by the pancreas, which stabilizes the pH of the chyme when released into the duodenum.Inhibition of gastric juice secretions and gastric motility, which in turn slows digestion in the stomach and retards gastric emptying.Relaxation of the hepatopancreatic ampulla and opening of the hepatopancreatic sphincter, which allows the flow of bile and pancreatic juices into the duodenum.The second regulatory agent of the digestive system is the nervous system.
