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.
In choosing a weight-loss program, watch out for these false claims:
- Lose weight without diet or exercise!
- Lose weight while eating all of your favorite foods!
- Lose 30 pounds in 30 days!
- Lose weight in specific problem areas of your body!
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.
