Do you need to lose weight? Have you been thinking about trying a weight-loss program? Diets and programs that promise to help you lose weight are advertised everywhere—through magazines and newspapers, radio, TV, and websites. Are these programs safe? Will they work for you?
This fact sheet provides tips on how to identify a weight-loss program that may help you lose weight safely and keep the weight off over time. It also suggests ways to talk to your health care provider about your weight. He or she may be able to help you control your weight by making changes to your eating and physical activity habits. If these changes are not enough, you may want to consider a weight-loss program or other types of treatment.
Talking to your health care provider about your weight is an important first step. Doctors do not always address issues such as healthy eating, physical activity, and weight control during general office visits. It is important for you to bring up these issues to get the help you need. Even if you feel uneasy talking about your weight with your doctor, remember that he or she is there to help you improve your health.

Talk to your doctor about safe and effective ways to control your weight. (See call out box for sample questions.)
He or she can review any medical problems that you have and any drugs that you take to help you set goals for controlling your weight. Make sure you understand what your doctor is saying. Ask questions if you do not understand something.
You may want to ask your doctor to recommend a weight-loss program or specialist. If you do start a weight-loss program, discuss your choice of program with your doctor, especially if you have any health problems.
What should I look for in a weight-loss program?
Successful, long-term weight control must focus on your overall health, not just on what you eat. Changing your lifestyle is not easy, but adopting healthy habits may help you manage your weight in the long run.
Effective weight-loss programs include ways to keep the weight off for good. These programs promote healthy behaviors that help you lose weight and that you can stick with every day.
Safe and effective weight-loss programs should include
- a plan to keep the weight off over the long run
- guidance on how to develop healthier eating and physical activity habits
- ongoing feedback, monitoring, and support
- slow and steady weight-loss goals—usually ½ to 2 pounds per week (though weight loss may be faster at the start of a program)
Some weight-loss programs may use very low-calorie diets (up to 800 calories per day) to promote rapid weight loss among people who have a lot of excess weight. This type of diet requires close medical supervision through frequent office visits and medical tests. For more guidance on this type of diet, read the WIN fact sheet Very Low-calorie Diets.
What if the program is offered online?
Many weight-loss programs are now being offered online—either fully or partly. Not much is known about how well these programs work. However, experts suggest that online weight-loss programs should provide the following:
- structured, weekly lessons offered online or by podcasts support tailored to your personal goals
- support tailored to your personal goals
- self-monitoring of eating and physical activity using handheld devices, such as cell phones or online journals
- regular feedback from a counselor on goals, progress, and results, given by email, phone, or text messages
social support from a group through bulletin boards, chat rooms, and/or online meetings
Whether the program is online or in person, you should get as much background as you can before deciding to join.

If a weight-loss program is not a good option for you, ask your health care provider about other types of treatment. Prescription drugs, combined with lifestyle changes, may help some people lose weight. For some people who have obesity, bariatric surgery on the stomach and/or intestines may be an option. See the Resources section for more information on bariatric surgery.
