There is a lot of information on Leptin written for a scientific or medical background but I wanted to find articles and posts from credible sources that I could get through without making my head spin but at the same time not so dumbed down that other potentially important and interesting threads were lost.
What is Leptin?
Leptin is a hormone produced by fat cells that maintains the energy balance in the body, regulates hunger by acting on receptors in the brain, specifically the hypothalamus, where it counteracts the effects of feeding stimulants from the gut and the brain and produces an appetite suppressant. I have seen it described as the King of hormones because of its effects on metabolism, the immune system, reproduction and bone mass. Now for some unexplained reason, whenever I think of Leptin I see Yul Brynner in my head. Funny how the mind works…
I still don’t get it
Essentially, Leptin tells the brain that the body has had enough to eat and has adequate stores of fat. So at this level it’s a fairly simple process to understand. You eat, Leptin levels go up and you feel full so you stop eating. If you’re overweight or obese then you will generally have higher leptin levels, if you’re leaner then your levels will be lower.
