Non-clinical programs may or may not be commercially operated, such as through a privately-owned weight loss chain. They often use books and pamphlets that are prepared by health-care providers. These programs use counselors (who usually are not health-care providers and may or may not have training) to provide services to you. Some programs require participants to use program's food or supplements.

Other weight loss methods used to treat severely overweight patients include low-calorie diets, prescription weight loss drugs and surgery. If you are considering a weight loss program and you have medical problems, or if you are severely overweight, programs run by trained health professionals may be best for you. These professionals are more likely to monitor you for possible side effects of weight loss and to talk to your doctor when necessary.

The key to successful weight loss is making changes in your eating and physical activity habits that you will be able to maintain for rest of your life. The first step is to look at your eating and physical activity habits, thus uncovering behaviors such as television watching, that lead you to overeat or be inactive. Next you'll need to learn how to change those behaviors.
