No such thing as bad carbs?

If you find it difficult to say no to so-called "bad' carbs like white bread, potatoes, and sweets, Dr. Glenn Gaesser has good news for you! Having analyzed hundreds of studies on the effects of carbs and weight gain, Dr. Gaesser has concluded that high-carbohydrate or high-glycemic diets don't lead to weight gain. (Read more about the glycemic index on our Gycemic Index topic page.)

According to Dr. Gaesser, author of It's the Calories, Not the Carbs, people who eat high carbohydrate diets tend to be thinner and healthier than people who don't. Furthermore, he says, high glycemic foods are not necessarily unhealthy and do not impede weight loss efforts.

Of course, this runs contrary to the current dietary dogma, which holds that excessive consumption of high glycemic carbohydrates (foods that cause a quick, sharp rise in blood sugar) can increase your risk of obesity, diabetes, and heart disease. Most nutritionists also advise dieters to emphasize low-glycemic (or "good") carbohydrates for better appetite control.
