PLEASE PLEASE PLEASE SUSAN. Do not try to lose weight fast. First you must seek medical attention and find out what is causing the weight gain. Then contact me at healthyonefitness.com. I would love to help you answer your weight loss questions. I would not run on a treadmill until you have lost some weight. It is soooooooo hard on the joints. Start out walking. I bet you will see your weight drop just from that activitiy. Make sure you walk properly on a treadmill. It is not the same as walking down the street. Please take care. I am happy to assist you. Pam
