"Muffin-top" is a generally pejorative slang term used to describe the phenomenon of overhanging flesh when it spills over the waistline of pants or skirts in a manner that resembles the top of a muffin spilling over its paper casing. This generally occurs when a person wears low-rise jeans, hip-hugger pants, and/or midriff-baring tops that are too small.
The question I have is why is this problem so widespread? I don’t have all the answers, but I believe that High Fructose Corn Syrup is a major culprit in this phenomenon. High fructose corn syrup was virtually unheard of until the 1970's when it was added to many foods and beverages, replacing white sugar and other sugars. Food manufacturers found this simple sugar tasted good and was a lot cheaper to use than other sweeteners. It didn't take long before high fructose corn syrup was added to everything, including bread and many processed foods. Perhaps by coincidence (perhaps not) the rate of obesity began steadily increasing after high fructose corn syrup made its appearance on the supermarket shelves as a hidden ingredient in foods. Many nutritionists blame it for the spike in weight gain following the low-fat craze of the 1980s, since greater amounts of high fructose corn syrup were added to products such as low fat cookies to make up for the taste lost by reducing the fat.
There are many reasons why high fructose corn syrup is bad for health and especially bad for people trying to lose weight. According to medical doctor and noted health expert Dr. Joseph Mercola, high fructose corn syrup is the sweetener most easily metabolized by the body directly into fat. Drinking just one can of soda pop puts 40 grams of high fructose corn syrup into your body, which is more than the American Medical Association's recommended daily allowance for all sweeteners! Drinking a can of pop along with eating a sandwich on white bread with high fructose corn sweetened-grape jelly and peanut butter can put your consumption sky-high. This manufactured fructose is sweeter than sugar in an unhealthy way, and is digested differently in a bad way. Research has shown that "high-fructose corn syrup" goes directly to the liver, releasing enzymes that instruct the body to then store fat! This may elevate triglyceride (fat in blood) levels and elevate cholesterol levels. This fake fructose may slow fat burning and cause weight gain. Other research indicates that it does not stimulate insulin production, which usually creates a sense of being full. Therefore, people may eat more than they should
Within the body, high fructose corn sweetener is processed very differently from natural sugars found in fruits and other food sources. Dr. Elizabeth Parks, writing in the Journal of Nutrition in 2008, states that high fructose corn syrup is quickly converted by the liver directly into fats, which are then stored. Some are stored directly at the liver. These can lead to raised cholesterol levels as well as create conditions ripe for insulin resistance, a precursor to Type II (adult-onset) diabetes. Worse yet, high fructose corn syrup is also a trigger food for some people; ingesting even a small amount of high fructose corn syrup sets up a craving in the body akin to an alcoholic's craving for more booze once they take a single sip.
The only way to make lasting changes is to focusing on natural, whole, unprocessed foods. While fructose does exist in fruits, these natural plant foods also contain several vitamins and minerals that effectively disable the ill effects of the fructose they contain. When you're eating processed and prepared foods, you're often getting the desired taste but completely missing the nutritional value of your food. To truly take control of your weight, you must become aware of the foods that damage your body, and the foods that nourish and heal you. More often than not, if you suspect a food is unhealthy for you, you're right. Inspect your labels, or better yet, try eating foods that don't come packaged and processed for a couple of weeks and note the difference in your weight and overall health.
