In an earlier post, I mentioned some reasons to avoid altered corn sweeteners. In the next few days, I’ll tell you exactly what this slow poison has taken away from our bodies and why these things are so important to make our bodies function properly.
Today’s focus is on the hormone, Leptin. According to Wikipedia:
Leptin acts on receptors in the hypothalamus of the brain where it inhibits appetite by (1) counteracting the effects of neuropeptide Y (a potent feeding stimulant secreted by cells in the gut and in the hypothalamus); (2) counteracting the effects of anandamide (another potent feeding stimulant that binds to the same receptors as THC, the primary active ingredient of marijuana); and (3) promoting the synthesis of ?-MSH, an appetite suppressant. This inhibition is long-term, in contrast to the rapid inhibition of eating by cholecystokinin (CCK) and the slower suppression of hunger between meals mediated by PYY3-36. The absence of a leptin (or its receptor) leads to uncontrolled food intake and resulting obesity. Several studies have shown that fasting or following a very-low-calorie diet (VLCD) lowers leptin levels. It might be that on short-term leptin is an indicator of energy balance. This system is more sensitive to starvation than to overfeeding. That is, leptin levels do not rise extensively after overfeeding. It might be that the dynamics of leptin due to an acute change in energy balance are related to appetite and eventually to food intake. Although this is a new hypothesis, there are already some data that support it.
There is some controversy regarding the regulation of leptin by melatonin during the night. One research group suggested that increased levels of melatonin caused a downregulation of leptin. However, in 2004, Brazilian researchers found that in the presence of insulin, “melatonin interacts with insulin and upregulates insulin-stimulated leptin expression”, therefore causing a decrease in appetite whilst sleeping.
In March 2010, researchers reported that mice with type 1 diabetes treated with leptin alone or in conjunction with insulin did better (blood sugar didn’t fluctuate as much, cholesterol levels went down and they didn’t form as much body fat) than mice with type 1 diabetes treated with insulin alone, raising the prospect of a new treatment for diabetes.
HFCS cuts back on your body’s ability to produce Leptin, therefore many people who have indulged in corn sugars over the years have had a natural supply of leptin taken from them. They simply do not know when to stop eating. Even though this seems like a gruesome portrayal of the deadly sin, Gluttony, from the movie “Seven”, it’s not that intense, but taking in super-size portions of fast foods and over-sized casual restaurant servings caters to this design, and many of the foods that are served contain some form of altered corn sugar, be it in the sodas or mixers in drinks, or a dextrose-enhanced sauce use to glaze a serving of chicken or in certain side dishes. Indulge in the treat of dining out occasionally, but do so in an educated manner, to avoid the altered corn sugars that might make you want to order more than your body should take in. Japanese restaurants are a good choice, as the food is usually prepared right before you. Mexican is also a good choice, as the sweet choices are limited. Most chain restaurants have websites that contain nutrition listings of caloric content, ingredients, and fat content. Use the web as your guide when looking for non-corn-sweetened dishes.
Over the last few years, some commercial diet aids have come on the market to replace the leptin that was taken away by corn sweetener consumption, but the best way to get your leptin production back on track is to avoid that which took it away in the first place. You will slowly find smaller meals to be more satisfying and no longer want to take on the super-size portions. A meal of miso soup, California Roll, and green tea can soon be as filling as a 1/4 dressing-laden burger, large fries, and a 32-oz. cola. Take back what the food corporations took away from you in their attempt to cut costs, and you will be more satisfied in so many ways.
