Is orange juice the best way to kick start one's metabolism in the morning after waking up?

Part of a good start: In general, foods are in their healthiest form with a minimum of processing. So an orange provides a better ratio of fiber and vitamins to sugar than orange juice. But orange juice is often fortified with calcium and vitamin d. For people with diabetes or who have trouble with low sugar spells, it needs to be balanced with some protein.

No: Orange juice is very high in sugar and is generally something that causes weight gain. Eating whole fruits and vegetables that are raw is much more effective along with an exercise program
