Limiting Fructose To Lose Weight Quickly

Low-carbohydrate diets do help weight loss as there is a reduction in the intake of a kind of sugar that the body rapidly converts into fat, as per new research.
A researcher has determined that fructose, normally present in processed carbohydrates, becomes fat lot quickly than glucose and sucrose. All three are types of sugar but the body metabolizes them in different ways.

The study concluded that fructose evades sugar's normal metabolic pathway via the liver. The liver determines if sugar that enters should be stored as glycogen, used for energy, or changed to the kind of body fat called as triglycerides.

The author, Dr. Elizabeth Parks said that the movement of fructose is not controlled by these pathways, leading to higher triglyceride synthesis. This study summarized that fructose is rapidly converted by the body into fat.

Parks, said the study shows that the kind of carbohydrate you eat may be equally essential for weight loss as reasons like counting calories.

High amounts of fructose occur naturally in fruit. But it is also added as a sweetener to various processed foods, especially as high-fructose corn syrup.
In the study, researchers made 6 healthy volunteers drink 3 different fruit drinks for breakfast. One drink had just glucose, one drink was partly glucose and partly fructose and the last drink had 25% glucose and 75% fructose.

The subjects consumed a normal lunch nearly 4 hours after having every drink.
The researchers concluded that the method in which the body converts sugar to fat increased dramatically among subjects on consumption of the higher fructose drinks.
Also, the subjects' bodies conserved more fats from lunch after the consumption of such drinks.

Parks said, that this was an underestimation of the result of fructose as these persons had drank the drinks and as the subjects were healthy, lean and could handle the fructose quite quickly.

According to Parks consumption of sugar is not the sole factor for an increasing North American obesity epidemic. But controlling processed carbohydrates is still an effective method for weight control
