Successful weight-loss treatments include setting goals and making lifestyle changes, such as eating fewer calories and being physically active. Medicines and weight-loss surgery also are options for some people if lifestyle changes aren’t enough.
Set Realistic Goals
Setting realistic weight-loss goals is an important first step to losing weight.
- Try to lose 5 to 10 percent of your current weight over 6 months. This will lower your risk for coronary heart disease (CHD) and other conditions.
- The best way to lose weight is slowly. A weight loss of 1 to 2 pounds a week is do-able, safe, and will help you keep off the weight. It also will give you the time to make new, healthy lifestyle changes.
- If you’ve lost 10 percent of your body weight, have kept it off for 6 months, and are still overweight or obese, you may want to consider further weight loss.
For Children and Teens
- If your child is overweight or at risk for overweight or obesity, the goal is to maintain his or her current weight and to focus on eating healthy and being physically active. This should be part of a family effort to make lifestyle changes.
- If your child is overweight or obese and has a health condition related to overweight or obesity, your doctor may refer you to a pediatric obesity treatment center.
Lifestyle changes can help you and your family achieve long-term weight-loss success. Example of lifestyle changes include:
- Focusing on balancing energy IN (calories from food and drinks) with energy OUT (physical activity)
- Following a healthy eating plan
- Learning how to adopt healthy lifestyle habits
Over time, these changes will become part of your everyday life.
Cutting back on calories (energy IN) will help you lose weight. To lose 1 to 2 pounds a week, adults should cut back their calorie intake by 500 to 1,000 calories a day.
- In general, having 1,000 to 1,200 calories a day will help most women lose weight safely.
- In general, having 1,200 to 1,600 calories a day will help most men lose weight safely. This calorie range also is suitable for women who weigh 165 pounds or more or who exercise routinely.
These calorie levels are a guide and may need to be adjusted. If you eat 1,600 calories a day but don’t lose weight, then you may want to cut back to 1,200 calories. If you’re hungry on either diet, then you may want to add 100 to 200 calories a day.
Very low-calorie diets with fewer than 800 calories a day shouldn’t be used unless your doctor is monitoring you.
For overweight children and teens, it’s important to slow the rate of weight gain. However, reduced-calorie diets aren’t advised unless you talk with a health care provider.
Healthy Eating Plan
A healthy eating plan gives your body the nutrients it needs every day. It has enough calories for good health, but not so many that you gain weight.
A healthy eating plan is low in saturated fat, trans fat, cholesterol, sodium (salt), and added sugar. Following a healthy eating plan will lower your risk for heart disease and other conditions.
Healthy foods include:
- Fat-free and low-fat dairy products, such as low-fat yogurt, cheese, and milk.
- Protein foods, such as lean meat, fish, poultry without skin, beans, and peas.
- Whole-grain foods, such as whole-wheat bread, oatmeal, and brown rice. Other grain foods include pasta, cereal, bagels, bread, tortillas, couscous, and crackers.
- Fruits, which can be fresh, canned, frozen, or dried.
- Vegetables, which can be fresh, canned (without salt), frozen, or dried.
Canola and olive oils, and soft margarines made from these oils, are heart healthy. However, you should use them in small amounts because they’re high in calories.
You also can include unsalted nuts, like walnuts and almonds, in your diet as long as you limit the amount you eat (nuts also are high in calories).
The National Heart, Lung, and Blood Institute’s “Aim for a Healthy Weight” patient booklet provides more information about following a healthy eating plan.
Foods to limit. Foods that are high in saturated and trans fats and cholesterol raise blood cholesterol levels and also might be high in calories. Fats and cholesterol raise your risk for heart disease, so they should be limited.
Saturated fat is found mainly in:
- Fatty cuts of meat, such as ground beef, sausage, and processed meats (for example, bologna, hot dogs, and deli meats)
- Poultry with the skin
- High-fat dairy products like whole-milk cheeses, whole milk, cream, butter, and ice cream
- Lard, coconut, and palm oils, which are found in many processed foods
Trans fat is found mainly in:
- Foods with partially hydrogenated oils, such as many hard margarines and shortening
- Baked products and snack foods, such as crackers, cookies, doughnuts, and breads
- Foods fried in hydrogenated shortening, such as french fries and chicken
Cholesterol mainly is found in:
- Egg yolks
- Organ meats, such as liver
- Whole milk or whole-milk products, such as butter, cream, and cheese
Limiting foods and drinks with added sugars, like high-fructose corn syrup, is important. Added sugars will give you extra calories without nutrients like vitamins and minerals. Added sugars are found in many desserts, canned fruit packed in syrup, fruit drinks, and nondiet drinks.
Check the list of ingredients on food packages for added sugars like high-fructose corn syrup. Drinks that contain alcohol also will add calories, so it’s a good idea to limit your alcohol intake.
Portion size. A portion is the amount of food that you choose to eat for a meal or snack. It’s different from a serving, which is a measured amount of food and is noted on the Nutrition Facts label on food packages.
Anyone who has eaten out lately is likely to notice how big the portions are. In fact, over the past 40 years, portion sizes have grown significantly. These growing portion sizes have changed what we think of as a normal portion.
Cutting back on portion size is a good way to eat fewer calories and balance your energy IN.
Food weight. Studies have shown that we all tend to eat a constant “weight” of food. Ounce for ounce, our food intake is fairly consistent. Knowing this, you can lose weight if you eat foods that are lower in calories and fat for a given amount of food.
For example, replacing a full-fat food product that weighs 2 ounces with a low-fat product that weighs the same helps you cut back on calories. Another helpful practice is to eat foods that contain a lot of water, such as vegetables, fruits, and soups.
Being physically active and eating fewer calories will help you lose weight and keep weight off over time. Physical activity also will benefit you in other ways. It will:
- Lower your risk for heart disease, heart attack, diabetes, and cancers (such as breast, uterine, and colon cancers)
- Strengthen your heart and help your lungs work better
- Strengthen your muscles and keep your joints in good condition
- Slow bone loss
- Give you more energy
- Help you relax and better cope with stress
- Allow you to fall asleep more quickly and sleep more soundly
- Give you an enjoyable way to share time with friends and family
The four main types of physical activity are aerobic, muscle-strengthening, bone strengthening, and stretching. You can do physical activity with light, moderate, or vigorous intensity. The level of intensity depends on how hard you have to work to do the activity.
People vary in the amount of physical activity they need to control their weight. Many people can maintain their weight by doing 150 to 300 minutes (2 hours and 30 minutes to 5 hours) of moderate-intensity activity per week, such as brisk walking.
People who want to lose a large amount of weight (more than 5 percent of their body weight) may need to do more than 300 minutes of moderate-intensity activity per week. This also may be true for people who want to keep off weight that they’ve lost.
You don’t have to do the activity all at once. You can break it up into short periods of at least 10 minutes each.
If you have a heart problem or chronic disease, such as heart disease, diabetes, or high blood pressure, talk with your doctor about what types of physical activity are safe for you. You also should talk with your doctor about safe physical activities if you have symptoms such as chest pain or dizziness.
Children should get at least 60 minutes or more of physical activity every day. Most physical activity should be moderate-intensity aerobic activity. Activity should vary and be a good fit for the child’s age and physical development.
Many people lead inactive lives and might not be motivated to do more physical activity. When starting a physical activity program, some people may need help and supervision to avoid injury.
If you’re obese, or if you haven’t been active in the past, start physical activity slowly and build up the intensity a little at a time.
When starting out, one way to be active is to do more everyday activities, such as taking the stairs instead of the elevator and doing household chores and yard work. The next step is to start walking, biking, or swimming at a slow pace, and then build up the amount of time you exercise or the intensity level of the activity.
To lose weight and gain better health, it’s important to get moderate-intensity physical activity. Choose activities that you enjoy and that fit into your daily life.
A daily, brisk walk is an easy way to be more active and improve your health. Use a pedometer to count your daily steps and keep track of how much you’re walking. Try to increase the number of steps you take each day. Other examples of moderate-intensity physical activity include dancing, gardening, and water aerobics.
For greater health benefits, try to step up your level of activity or the length of time you’re active. For example, start walking for 10 to 15 minutes three times a week, and then build up to brisk walking for 60 minutes, 5 days a week.

Changing your behaviors or habits related to food and physical activity is important for losing weight. The first step is to understand which habits lead you to overeat or have an inactive lifestyle. The next step is to change these habits.
Below are some simple tips to help you adopt healthier habits.
Change your surroundings. You might be more likely to overeat when watching TV, when treats are available at work, or when you’re with a certain friend. You also might find it hard to motivate yourself to be physically active. However, you can change these habits.
- Instead of watching TV, dance to music in your living room or go for a walk.
- Leave the office break room right after you get a cup of coffee.
- Bring a change of clothes to work. Head straight to an exercise class on the way home from work.
- Put a note on your calendar to remind yourself to take a walk or go to your exercise class.
Keep a record. A record of your food intake and the amount of physical activity that you do each day will help inspire you. You also can keep track of your weight. For example, when the record shows that you’ve been meeting your physical activity goals, you’ll want to keep it up. A record also is an easy way to track how you’re doing, especially if you’re working with a registered dietitian or nutritionist.
Seek support. Ask for help or encouragement from your friends, family, and health care provider. You can get support in person, through e-mail, or by talking on the phone. You also can join a support group.
Reward success. Reward your success for meeting your weight-loss goals or other achievements with something you would like to do, not with food. Choose rewards that you’ll enjoy, such as a movie, music CD, an afternoon off from work, a massage, or personal time.
