How High Fructose Corn Syrup Makes you Gain Weight

High Fructose Corn Syrup CandiesNew research from UT Southwestern Medical Center shows the amazing speed that our bodies make body fat from fructose. One of the reasons why low carb diets help you lose weight is that they reduce your intake of fructose.

Even though fructose, a type of sugar, is found naturally abundance in fruit, it is also added to many processed foods. Fructose is probably best known for its presence in the sweetener called high-fructose corn syrup (HFCS), which is typically 55 percent fructose and 45 percent glucose. It unfortunately has become the preferred sweetener for many food manufacturers. This is because it is cheaper, sweeter and easier to blend into beverages than table sugar.
Sugar Type As Important as Calories

Dr. Elizabeth Parks, lead author of the study , said her team’s findings infer that the right kind of carbohydrates you eat may be just as important in weight control as the number of calories you eat. The study appears in the Journal of Nutrition.

“The message from this study is powerful because body fat synthesis was measured immediately after the sweet drinks were consumed,” Dr. Parks said. “The carbohydrates came into the body as sugars, the liver took the molecules apart like tinker toys, and put them back together to build fats. All this happened within four hours after the fructose drink. As a result, when the next meal was eaten, the lunch fat was more likely to be stored than burned.

“This is an underestimate of the effect of fructose because these individuals consumed the drinks while fasting and because the subjects were healthy, lean and could presumably process the fructose pretty quickly. Fat synthesis from sugars may be worse in people who are overweight or obese because this process may be already revved up.”
