Tune in to Natural Appetite Control

We all know the important role that insulin plays in overall health, and in natural weightloss specifically. But now we are learning that a different hormone—leptin—may play an even greater role in health and weight loss than insulin.

Studies have shown that leptin regulates your brain’s hypothalamic activity, which in turn regulates much of your “autonomic” functions—those functions that regulate body temperature, heart rate, hunger, the stress response, fat burning or storage, and blood sugar levels. Another very recent study also reveals leptin’s importance in directly regulating how much sugar your liver manufactures.

In other words, leptin is directly related to conditions such as heart disease, obesity, diabetes, osteoporosis, autoimmune diseases, reproductive disorders, etc. It does this by telling other hormones, such as insulin and female hormones, whether or not to turn on maintenance and repair mechanisms, as well as by helping to control areas of your brain that regulate thyroid levels and the sympathetic nervous system.

Are You Tuned In to Leptin?

Dr. Ron Rosedale believes people become leptin-resistant by the same general mechanism that causes people to become insulin-resistant—overexposure to high levels of the hormone.

It’s like the frog in the boiling water. If you toss a frog into boiling water, it will jump right out. But if you place the frog in warm water and gradually increase the heat, he will soon be sitting quite happily (and quite dangerously) in boiling water.

So it is with leptin. As sugar gets metabolized in fat cells, fat releases surges in leptin. Over time, those surges become so frequent and expected, that the leptin is not released…in other words, you become leptin-resistance, since the “danger signal” no longer getting through.

Once you tune back in to leptin, you “jump out of the water” so to speak. In other words, high leptin levels can now scream to your brain that you have too much fat and that you better start burning some off. Your brain can now start burning off the fat you’ve been storing, and using it for energy. Best of all, your will suppress your hunger signals and regain appetite control.
