In almost every post lately what I’m writing about seems to effect either leptin or ghrelin. So this post is mostly for reference. The reason they come up so often is they are the two key hormones regulating hunger. Ghrelin signals to our brain to increase appetite, while leptin is a major appetite suppressor and regulates energy balance by inhibiting hunger.
This is why they are mentioned so frequently. Because when you change your diet, or body weight, or routine, or don’t get enough sleep, or so many other things – it effects our leptin or ghrelin levels. This can drive us to eat more or less than we physiologically need.
That’s mainly what you need to know when posts mention leptin/ghrelin increasing/decreasing. But if you want to geek out the full article is here.
Any questions, get in touch.
