Carbs are the basic building blocks of life. I.M.O low-carb diets are not giving you the nutrients required to be healthy and function. I have also heard that low carb diets are too high in protein, and this is heard on your heart and your cholesterol. A well-balanced diet which is low in processed foods, refined sugars, and contains a reasonable abmount of fat is really the only diet plan I reccommend. You need to eat carbs, protein, vegetables, and fruits. even fats are necessary. It is the quality of these foods that you eat which makes thedifference. For example, eating a whole box of low fat crackers is not a good idea, no matter how many calories are in them. Eating all vegetables is obviously missing out on the other necessary building blocks of metabolism for your body. The .A.M.A does not encourage any elimination type diets-those which completely or nearly eliminate an entire food group.
Are you trying to lose weight, or is there another reason you are considering a low carb diet?
