I read an article somewhere and it said you can drink juice for lunch or breakfast rather then eating a meal. is this okay to do?

Generally no: Substituting liquid for food generally is not a good way to diet or lose weight. Your body still needs essential nutrients that are delivered by food. Everyone has different eating habits and if you feel ok only drinking juice at breakfast or lunch this is fine. I believe the best way to ensure a healthy weight is to eat appropriate portion sizes.

Real food=real life: A small amount of juice can supplement a healthy meal, but it does not make up a meal. Your meals should contain good protein, healthy fat, and complex carbohydrates. This means eating real whole food to fuel your real healthy life.

Balanced meals: A good and healthy meal is one which is balanced . Has energy giving carbohydrates , fats , body building proteins and protective group alike fruits and vegetables. Hence a good meal has to have starch, protein and little fat. Fruit juice is not a meal substitute .
