The Effect Of Diet And Exercise On Obese Women - 923 Words

Factors Proper nutrition is a key factor when it comes to regulating body weight. If an individual is meeting their caloric recommendations of intake, then weight gain rarely occurs. Weight gain occurs when individuals exceed their caloric recommendations (energy in is greater than energy out). Recent research suggests that dietary restrictions in addition to exercise promotes more weight loss than dieting alone or exercising alone (12). A study by Foster-Schubert, and et. al., which focused on the effect of diet and exercise in overweight to obese postmenopausal women, showed results that support the statement that diet and exercise leads to greater weight loss when combined. The results of the study showed that the dieting alone group†¦show more content†¦Aerobic training has higher oxygen consumption (VO2), oxidizes more lipids (when compared to strength training), and utilizes carbohydrates as fuel energy. In more recent studies, it is suggested that strength training (ST) play s a significant role in regulating body weight once weight loss has occurred (4). It is also suggested that ST results in unique effects that aerobic exercise alone cannot achieve (4). Viewing ST alone and how it affects weight loss, it is concluded that weight loss occurs due to muscle hypertrophy. During ST, resting metabolic rate increases due to the increase in muscle mass, this in turn increases the total daily energy expenditure. When an individual is trying to lose weight through means of exercises, ST can complement aerobic training and aid in more efficient weight loss. For each type of exercise, it can then be broken down into intensity and duration. Exercise intensity is the measure of how hard the body has to work during exercise. There are three levels to intensity: low, moderate, and high. If an individual is new to exercise they would start at low intensity and progress from there. The prescription of higher physical activity goals does improve the individual’s outcome. In a study performed by Jeffery, Wing, Sherwood, and Tate, the results of high intensity exercise were correlated with weight loss (10). It is important to point out that the subjects of this trial did not start out at a high
