Activities that can speed up metabolism include adding muscle mass; eating regular meals that include protein; drinking coffee, green tea and cold water; and eating organic produce. Some activities to avoid include having more than two alcoholic drinks per day and skipping sleep or meals.
Eating an early breakfast jump starts the metabolism. Avoid eating just before bedtime. Drink coffee in moderation. Caffeine is a stimulant that excites the central nervous system, increasing respiration and heart rate as well as the metabolism. Drink ice cold water to encourage the body to work hard to warm the core, which increases the metabolic rate.
Avoid anemia by consuming iron from beans, leafy greens and fortified cereals. Without iron, the body produces fewer red blood cells, which can lead to fatigue and a slower metabolism. Eat spicy foods, such as cayenne pepper and chiles, because these heat up the body and boost metabolism.
Incorporate interval training into workouts. This stimulates muscle to burn more fat. During workouts, use heavy weights, and complete each rep slowly. This maximizes muscle growth and stimulates the metabolism.
Consuming fish oil supplements helps the body's fat-burning enzymes. Tuna, salmon and sardines also provide omega-3 fatty acids that aid metabolism. Eat sufficient protein to help muscles rebuild after workouts. Protein also creates a feeling of fullness and helps to stop overeating. Avoid alcoholic drinks because the liver turns the alcohol into acetate and burns it instead of fat. Get plenty of rest because getting fewer than eight hours of sleep per night slows the metabolism.
