Eat the Right Type of Carbs

It is the type, rather than the amount, of carbohydrates in your diet that helps determine your body weight, according to scientific studies. Nutrition researchers studied the height and weight of 572 healthy people in Massachusetts and asked them to report their weekly intake of carbohydrates during a one-year period. They found that overweight people ate more refined ("bad") carbohydrates than those who weigh less.

Refined carbohydrates are, for example, those found in sugar, white breads, pasta, crackers, and cereals. Refined carbohydrates are "bad" because they have what is called a high glycemic index, meaning that these foods cause a sudden and sharp increase in blood sugar. If this blood sugar is not used by the body, it is stored as fat.
