Wellness All diets should be balanced because despite equivalent calorie counts not all types of food are equal. For example, a calorically-balanced diet high in trans-fats can damage the heart and facilitate the change of fat molecules to surplus fat. A balanced diet plan is a diet saturated in fiber ( fresh fruits and vegetable ) and low in saturated or pet fat. Trans-fats, within fast and junk food often, ought to be avoided altogether.
