Leptin is a hormone created by the fat cells in the body which functions as a control to appetite and hunger sensations. It controls our tendency to eat more or to eat less by telling the brain that it has enough food, so the brain stops the craving for more. As a result, the individual does not eat more than needed and does not become overweight. This is the primary premise behind the ultra popular online diet called The Venus Factor.
Leptin is carried by the bloodstream and into the brain and sends a signal to the brain area that controls when and how much we eat. The leptin also tells the brain how much body fat is in the body. Lots of leptin signal the brain that there is plenty of fat stored, while low-level signals that fat stored is low and that there’s a need to eat to avoid starvation.
What is Leptin Resistance?
The function of leptin is to tell the brain that the body doesn’t need to eat some more and that it can burn calories at a normal rate. This way, leptin regulates our eating and our appetite.
However, sometimes the leptin in the blood does not work, which causes us to have no control over the amount of food to eat. The brain is not getting any message from leptin that it already has enough fat; it has developed a resistance to leptin.
There is really no known specific reason why leptin resistance happens. Maybe the amount of leptin in the body is not enough to reach the brains. Or maybe the leptin receptor in the brain is not working properly and is not receiving the messages. When the brain doesn’t receive the leptin signal, it thinks that the body is hungry, even though the person has just eaten. It thinks that you need to conserve energy, so it makes you feel lethargic resulting in fewer calories burned. Thus weight gain is not always because you eat more and exercise less, it is the outcome of leptin resistance, a defect of the hormones.
How can we fight leptin resistance?
Leptin resistance is a complicated problem, but it’s not permanent. These are some of the things you can do:
- Avoiding processed food
- Eating Soluble Fiber
- Getting enough sleep
- Lowering our triglycerides
- Eating plenty of protein
If you want to make lasting health changes or lose weight and keep it off, you have to fix your leptin. To make your leptin work, you have to do the same things that are generally associated with good health.
