4 Ways to Boost Metabolism...,by Dr. Weil

1. Eat small meals throughout the day. This encourages steady caloric burn and a consistent metabolism.
2. Choose healthy carbohydrates. Replace refined, high-glycemic-index carbs with unrefined, low-glycemic choices. The latter do not cause the spikes in blood glucose levels that encourage the storage of fat.
3. Use spices. Capsaicin (the compound that gives chili peppers their bite), black pepper and ginger all boost the generation of heat in the body, leading to more calories burned.
4. Drink green tea. The main antioxidant polyphenol in green tea, known as epigallocatechin gallate or EGCG, stimulates the body to help burn calories. Dr. Weil recommends drinking a few cups of quality green tea every day.
