Since 1960 fat intake hasn't changed much. During the same time sugar intake has increased dramatically. According to the USDA, sugar and sweetener consumption has climbed from 113 pounds per person in 1966 to 147 pounds per person in 2001.
Some researchers point to high- fructose corn syrup, which is an inexpensive, commonly used sweetener, as a culprit in the obesity epidemic. The sheer availability of high calore, high glycemic food has led people to graze throughout the day on foods that are largely nutrient-poor and calorie-rich.
The glycemic index is one term one should be familiar with. The glycemic index is a measure of the body's physiological response to a particular food in comparison to glucose. Glucose is the form of sugar carried in the blood and used as fuel by all of the cells in the body. The glycemic index is a number betweel 0 and 100.

Their weight loss is more likely to occur as fat loss. That's because low-GI diets do not trigger the metabolic switch that increases fat storage rather than fat burning. It is important to realize that this type of diet is not simply a low-carbohydrate diet.
People who follow a low-GI diet can consume carbohydrates that do not elicit a high-GI response such as beans, lentils, barley, yams, sweet potatoes as well as a host of other foods. Even most fruits such as apples, oranges and grapefruit, all high in pectin, are low to moderate on the glycemic index, which makes them permissible on this diet plan when consumed in moderation. Just as simply restricting carbohydrates is not an effective weight loss strategy, simply restricting calories has not resulted in the preferential change in body composition of losing body fat rather than muscle mass. weight loss
