Stay active and exercise regularly. Sixty minutes a day is ideal, but everything (even climbing stairs and walking to school or work) counts. Aerobic and strengthening exercises can result is weight loss when combined with a calorie-reducing diet. Without exercise, dieting can cause the loss of muscle as well as fat. An aerobic exercise regimen burns fat, while building muscle. This may mean less dramatic weight loss, but since muscle tissue burns more calories than fat tissue, the result is longer lasting. Consistent, regular exercise actually strengthens the heart, resulting in more blood and oxygen flow throughout the body. A fitness regimen offers many psychological benefits, but the biggest payoff comes from an improved self image. Achieving fitness goals leads to self confidence, improved body image, self awareness and esteem.
