I strongly discourage athletes in training to limit carb intake. Carbs are the energy source for exercise, especially high intensity exercise (Oly lifting certainly is high intensity). Carbs should make up 60-70% of your diet. The key to weight loss while still maintaining carb intake is the glycemic index. You want to eat carbs that have a low glycemic index (Google "glycemic index" for more information).
Matt Denslinger wrote "Isn't 60-70% a little too much?Good question, Matt. With all the information from Atkins, it would seem that high carbohydrate diets are bad. But the Atkins diet is meant for the morbidly obese who have to lose a huge amount of fat. In the short term, Atkins turns the body into a fat burner from a carbohydrate burner. But weightlifters depend almost solely on the body stores of muscle glycogen. Only a high carbohydrate diet will ensure the quick refueling of those stores.
