Welcome to the Dr. Berg's Healthy Keto and Interminute Fasting Podcast, where Dr. Berg takes you on the journey for the truth about getting healthy and losing healthy weight. Let's talk about leptin. Leptin is mainly known as an appetite hormone. So the more you have,

the less hungry you are. But leptin also has a huge immune function that I want to talk about.

And as a side note, the Greek word for the word leptin means thin because of the suppression

of the appetite. When you increase leptin, the hunger goes away because there's a signal from the fat

cell to your brain, specifically the

hypothalamus, telling the brain we have enough nutrition or food. But when leptin is low,

you are hungry. Lepton is made by your fat cells and the intestinal cells. But here's a problem.

Chronically high levels of leptin start causing what's called

leptin resistance. Now this is very similar to insulin resistance where you have this high level of

insulin produced by consuming a lot of carbohydrates. And what happens over time is your receptors

start to downgrade and now you can't absorb that hormone anymore. Same exact thing happens

with leptin. High levels of leptin over a long period of time, kind of desensitize the receptor,

and now you don't get a lot of absorption of that hormone. Here's the problem, the feedback loops

that are supposed to go back to the fat cells really don't because of the blockage of the

receptor so the fat cell keeps making more and more and more but you have the situation where you have

all this leptin but it's not working so we have symptoms of a leptin deficiency starving and an excess as well and another purpose of leptin is to suppress both parts

of the immune system to calm inflammation down so people that don't have enough leptin have

higher risks of getting an autoimmune problem because they have way too

much inflammation and when you have a lot of inflammation in your body your immune system is actually
