One of the biggest misconceptions around today is that you should limit your carbohydrate intake when trying to lose weight. Myths like these have been given credibility due to high-profile stars like Jennifer Aniston claiming that they lost an incredible amount of weight by strictly following diets like the Atkins diet. Without going into the physiology behind this, it is simple enough to say that your body needs carbs to function, particularly those with an active lifestyle or who do a considerable amount of exercise.
When a person exercises regularly, their kilojoule requirements can often double and in some cases even treble. As carbs are the principal source of energy they are essential in all diets but especially for an active person.
