When the body depends on sugar for fuel, it impedes the general functions of leptin, the "general of the hormonal chain of command. Leptin is in payment of your pituitary hormones, which regulate the thyroid gland. The functions of the thyroid gland is to regulate how swiftly the body uses energy. If you have low power or are cold all the time, it's probably going to be thyroid related.
The thyroid is also responsible for detoxifying the body, flushing out impurities such as fluoride, chlorine, mercury, aluminum, pesticides, and other harmful toxins that we take in from the water, air, vaccines, dental fillings, and our diet. If the thyroid isn't operating at full potential, these toxins fetch in our cells and joints, causing lasting pain diseases such as fibromyalgia and rheumatoid arthritis.
The hormone leptin decides when to make us hungry, and therefore controls our metabolism. It works hand-in-hand with insulin, which becomes abnormalized when leptin levels come to be too high or too low. If we are a carbivore, we'll probably start to get hungry about two to three hours after we eat. From an evolutionary perspective, that's crazy. Nature (divine intelligence) is not that stupid.
Frequently going days at a time without a meal, our paleo, hunter-gatherer ancestors would have starved to death if they had to depend on complex carbohydrates (sugar) for fuel. But because they depended on fat-based ketones, the leptin hormone in their bodies were able to make their metabolism much more productive than that of the modern human. Subsequently, they could go much longer periods of time without getting hungry. This allowed for a much lower dietary caloric intake. Obesity was nonexistent.
They goal is not to increase your metabolism. Why would you want to make the engine in your car run hotter? They goal is to get your body to metabolize fat more efficiently. And the only way to do this by letting go of a carbohydrate-dependent diet and embracing a paleo diet that is based on ketones.
Leptin also orchestrates our parasympathetic, fight or flight response in the nervous system. Until your leptin levels are under balanced, you will constantly be in a state of anxiety because you will be physiologically reacting to everything. There won't be any saber tooth tigers to worry about, but, nevertheless, you will be acting as if there were. lasting anxiety over a duration of months and years can lead to lasting depression and fatigue. All of this is leptin-related.
