Leptin is a hormone that assists in regulating appetite and. . .

Leptin is a hormone that assists in regulating appetite and metabolism and was discovered in 1994. Leptin levels are proportional to body fat as it is released by fat cells.

obesity is said to lead to 30,000 premature deaths per year - shortening life by an average of nine years. leptin is an appetite suppressant, it stops ou eating too much.

It is thought that many obese people may have developed leptin resistance. In other words the body fails to respond to leptin signals. This begins a cycle where more leptin is produced.

The theory is that as you get fatter you also get less sensitive to the effects of leptin.
