Xenical is a practical alternative solution for those who needed additional assistance, beyond that of a low calorie diet and exercise, in the management of weight loss. Xenical is an oral prescription medication that helps the body eliminate unwanted fat. Xenical blocks up to 33% of the fat in the food you eat, this encourages your body to activate your own fat centers and leads to healthy weight loss over time. Remember whenever you are considering a new weight loss program to always consult a doctor. Because Xenical is a prescription medication you will need to share your medical history with a doctor to make sure Xenical is an appropriate treatment for you. Clinical studies have shown that over a 1-year trial, people who used Xenical along with a low calorie diet and moderate exercise lost more weight than those who did not use Xenical. The average weight loss for someone using just diet and exercise was approximately 6 lbs. Those who added Xenical to their weight loss program lost significantly more weight, approximately 13.5lbs.
