Some ways you can help your life

Exercise can control weight loss

Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories. The more intense the activity, the more calories you burn. You don't need to set aside large chunks of time for exercise to reap weight-loss benefits. If you can't do an actual workout, get more active throughout the day in simple ways — by taking the stairs instead of the elevator or revving up your household chores.

Exercise helps boost brain power

Not only does exercise improve your body, it helps your mental function, says certified trainer David Atkinson.

"Exercise increases energy levels and increases serotonin in the brain, which leads to improved mental clarity," says Atkinson, director of program development for Cooper Ventures, a division of the Cooper Aerobics Center in Dallas.

How protein helps your body

Proteins are also a major component of your cells. Outside of your cells, proteins constitute bone and soft tissue and help these structures to maintain their shape. Because they can be made into many different shapes and sizes, and they also constitute digestive enzymes, the antibodies in your blood, and serve many other functions. Proteins have many functions inside your cells as well. They perform all of the enzyme functions for energy production; they provide for repair of DNA when it is damaged; and, together with fats, they maintain the integrity of your cell's membrane. Proteins are located in your cell membrane, within the cell itself, and around your cells.

how people become overweight

Although there may be some genetic factors involved, the key reasons why many of us are increasing in weight include:

  • eating larger servings of meals and snacks.
  • consuming food or drinks that are high in energy.
  • not being as physically active.
