Vitamin C, the water soluble vitamin known for its effectiveness in treating scurvy and promoting collagen production, is also indicated as a major factor in weight management. Because your body doesn't store water-soluble vitamins when consumed in excess of your daily needs, but are excreted instead, it is important to consume vitamin C daily. Eat or drink vitamin C-rich foods in the morning to rev up metabolism and lose weight. Consult with your medical provider before making dietary changes or taking supplements.

Even without a structured exercise routine in the morning, people tend to be more active and get more exercise during the course of the day than at night.
