Metabolism. It's a complicated subject. Most people I know would like a faster one. What is it? Your metabolism is the process your body goes through to break down nutrients to provide energy for your body. It works around the clock, but sometimes not so well. The purpose of this article is to offer a number of different ways for you to boost your metabolism if you would like to lose weight or just eat more (for energy of course).

Heredity and age do play a role in metabolism. You can't change either of them, so the focus of this article is what you can do. It is important to note, though, that research suggests metabolism slows by 5% for every decade after the age of 40. If you're there already or just looking to lose weight, here are some things you can do.

Different macronutrients (protein, carbs, and fat) require different energy expenditures by the body in order to digest the food. Protein burns roughly 5x-6x more calories during digestion than a similar amount of calories of fat and about 3x more than carbohydrates. Eat your weight in protein grams and see your metabolic rate soar.

Water intake is also a major driver of metabolism. A lack of proper hydration can inhibit all bodily processes, metabolism included. A recent study showed that volunteers who drank 12 cups of water per day burned more calories than those who drank 8 cups and 4 cups. In order to kick your metabolism into high gear, drink one ounce of water per pound of body weight. If you exercise, add 16 ounces per 30 minutes. Ice water also boosts your metabolic rate as your body burns calories to increase the temperature.

Smaller, more frequent meals can also play a key role. I recommend six meals per day. Your body will burn more calories by kickstarting the digestion process more frequently throughout the day. It is also important to try to eat a serving of protein with every meal. Consistency is also key. Eating six meals one day and three the next can impact your metabolic rate. Skipping meals is dangerous for your metabolism. It is important to eat a high protein meal early in the morning to get your metabolism running again after a night of fasting.

I also recommend eating whole foods rather than those that are processed and typically loaded with chemicals, sugar, and fat. If you choose to eat a packaged food, make sure you read the food labels to understand the nutrition content of the food and what other harmful chemicals and additives may be in your food. Something like high fructose corn syrup tricks your brain and body and doesn't stimulate an insulin response, which can lead to overeating.

In terms of exercise, high-intensity interval training (HIIT) for cardio is much better for metabolism than long, slow and low-intensity training. Implementing a program that cycles through frequent bursts of sprinting followed by moderate jogging or walking can give you a great metabolic workout in just twenty minutes. Weight lifting can also have a huge impact. Not only does more muscle on your body mean more calories burned, but each individual workout can boost your metabolism for up to two days, assuming you work out until failure while targeting no more than twelve reps per exercise, but preferably eight.

Proper sleep is important for your body to function properly. I haven't seen much research suggesting that it has a direct impact on metabolism, however, you are much more likely to eat healthy, exercise, and implement the rest of this metabolism-boosting plan if you are well rested.

I caution everyone on the use of diet pills and other quick fixes. These rarely have a positive, long-term impact. If they did, our country wouldn't have the obesity rate it does.
