Ever had trouble sticking to a diet?

 

Crave foods?

 

Overweight?

 

Want to snack, especially at night?

 

These are all indications that you could have some Leptin issues. Leptin is a master hormone in the body that controls hunger and feelings of satiety. Leptin is secreted by adipose (fat) tissue, so the more overweight a person is, typically, the higher his leptin levels.

 

According to Mark’s Daily Apple: “Leptin is the lookout hormone – the gatekeeper of fat metabolism, monitoring how much energy an organism takes in. It surveys and maintains the energy balance in the body, and it regulates hunger via three pathways:

 

By counteracting the effects of neuropeptide Y, a potent feeding stimulant secreted by the hypothalamus and certain gut cells.

 

By counteracting the effects of anandamide, another feeding stimulant.

 

By promoting the production of a-MSH, an appetite suppressant.”

 

It is also directly tied to insulin levels. Many people these days are Leptin resistant and there are many health problems tied to this problem. High leptin levels have been tied to high blood pressure, obesity, heart disease and stroke, as well as blood sugar related problems.

 

High levels of Leptin and the accompanying leptin resistance can also decrease fertility, age you more quickly and contribute to obesity. If you’re trying to lose weight or improve a health problem, chances are you have Leptin resistance. If you can’t seem to stick to health changes, chances are you have Leptin resistance.

 

In other words, if you want to make lasting health changes or lose weight and keep it off, you have to fix your leptin. The good news is: if you’ve failed at diets or health changes in the past, it was likely because you failed to regulate your Leptin levels and doing so can help you finally make lasting changes. Leptin resistance and its related problems are a complex problem involving the endocrine system and reversing them requires more than simple calorie restriction or will power.

 

The Downward Spiral

 

Leptin is the satiety hormone produced by fat cells, so it would seem logical that those with more fat cells would produce more Leptin, which would signal the body to eat less food and weight would normalize. This over-simplified idea is great in theory, but doesn’t always occur, especially in those with damaged metabolisms or endocrine problems (which includes most overweight people).
