Strength training, interval training, omega-3 supplements, green tea and maintaining a calorie count equal to the resting metabolic rate are effective ways to boost metabolism, reports Health.com. In addition, eating breakfast, eating in small increments throughout the day and a protein-rich diet help speed up metabolism.
Strength and interval training boosts metabolism during exercise by utilizing more oxygen and burning energy more efficiently, according to Health.com. In addition, more energy is burned throughout the day, not just during exercise. Muscle also passively uses more energy than fat, and an increase in muscle percentage results in a higher resting metabolic rate.
