How can you improve your metabolism?

Healthy choices. My father taught me a great dietary system. He said "eat like a king in the morning, a prince in the afternoon, and a pauper at night." dinner should be your lightest meal. Don't starve yourself, that slows metabolism, eat healthy snacks between meals. Exercise to build muscle. Hydrate! b vitamins, coq10 (gives your muscles energy) and green tea or mate tea.
