Query: The Atkins Diet has helped me lose 30 pounds.

The Atkins diet has helped me lose 30 pounds and feel better than I have felt in years. Antacids used to be a constant companion, even on other diets. Now no indigestion or reflux. Another plus is the lack of hunger as fat a as protein stay with you much longer than carbohydrates. Dr. Atkins reports on many studies that show the advantages of his type of diet.If the low-fat, low calorie, high-carbohydrate diet worked we would be the skinniest and healthiest country on the planet!
