Believe it or not, there is an art and science to losing weight through exercise. Have you ever wondered why some people exercise a little and they look good while others seem to exercise all day and they look like they have been sitting on the couch eating potato chips instead? There is a direct relationship to how you exercise and what your body uses for fuel.

During exercise, the body uses most fat and carbohydrate as fuel. Protein is spared to act as fuel because the body keeps it in stock if you start starving. At low levels of prolonged exercise, our energy needs come from fat. Carbohydrates come more into play with higher intensity, short-term training.

Adequate protein intake is essential to maintain your lean body mass so that you can perform best. The source of energy and efficiency depends on what you ate before you started exercising and the intensity and duration of the workout. Professional endurance runners often throw pasta on the night before a big race because they know it is the best fuel for their specific workout.

Fat as fuel provides extensive calorie stores in an easily portable form. Fat weighs much less per. Calorie unit than protein or carbohydrate, but carbohydrate is more effective than fat. This is why it is difficult for people to exercise while trying to lose weight on one of these low fat diets. It does not give your body proper fuel to burn.

The best nutrition you can give your body for exercise is soy-based protein replacement of shakes with multi-vitamin supplements to target your specific needs. Just as there is art and science to practice, there is an art and science to fill your body for exercise. The better the nutrition, the easier it is to exercise, lose weight and keep it off for good.

For a performance athlete, it is important to maintain the efficiency edge from carbohydrates. Under normal training conditions, protein provides only approx. 6% of energy needs. The only food that provides energy for short-term fast-paced exercise is carbohydrate, while slow, steady aerobic exercise uses all three primary fuels.

Strong exercise involves minimal risks for healthy individuals, but can be risky for couch potatoes. You did not take all that weight in one day, so you can not expect to go out and run 10 miles the first time you try to lose it. Gradually work up to a realistic goal, and celebrate your small daily accomplishments. (With a pat on the back and not a donut, of course!)

The more you train, the more muscle you will also build. Remember not to get hung up on weighing yourself because muscle weighs more than fat. You may see the scale start to rise while your stomach is falling. This is a good thing.

It is much more important to focus on how you feel more than reaching a number in pounds.

The more you exercise, the more you will lose fat, and the more important it becomes to get good carbs to burn your body for exercise. You do not want to get to the point where your body robs itself of protein for fuel. Do not be afraid to eat fruits and vegetables, grains with grains, etc., while trying to lose weight with exercise. The worst thing you do is not eat anything.

So there really is an art and science to exercise and what you burn your body with is in direct relation to your desired level of activity. Small changes in your diet targeting your workouts can make the difference between success and failure in your weight loss efforts. Whatever you choose to do, always remember to feed your body with the best possible nutrition.
