Eating & Physical Activity to Lose or Maintain Weight

What options might help you lose weight?

Changing your eating habits is central to losing and maintaining your weight. To lose weight, you have to eat fewer calories and use more calories than you take in. This can be challenging for many people to do for an extended period of time. Emerging research shows that sticking with an eating plan may be more important to losing and maintaining weight than the type of eating plan you follow.

Follow a healthy eating plan

All your food and beverage choices count. Eating healthy is a journey shaped by many factors, including your age, weight, metabolism, food preferences, access to food, culture, and traditions; whether you are a man or woman; and the personal decisions you make over time. A healthy eating plan includes

  • a variety of vegetables, fruits, and whole grains, such as brown rice, oats, and whole-wheat bread
  • fat-free or low-fat dairy products such as milk, yogurt, and cheese and similar products such as soy beverages
  • a variety of protein foods, including seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products
  • oils, such as olive and canola oils and those found in nuts, olives, and avocados

Get regular physical activity

The Physical Activity Guidelines for Americans, 2nd edition (PDF, 14.2 MB) define regular physical activity as at least 150 minutes a week of moderate-intensity aerobic activity, such as brisk walking. A moderate-intensity aerobic activity makes your heart beat faster and makes you breathe harder but does not overwork or overheat you. This type of physical activity is safe for most people.

People with physical disabilities also can do certain activities, such as wheelchair aerobics or basketball. Talk with your doctor about the types of physical activity that might work well with your abilities.

If you have a health condition such as heart disease, high blood pressure, or diabetes, talk with your doctor before you start regular physical activity. Your doctor can review with you the types and amounts of physical activity that might suit your lifestyle, interests, and skills.

In addition to metabolism slowing during weight loss, your body needs fewer calories at your new, lower weight. Hormonal and other factors also tend to promote weight regain. People who have kept weight off long-term report needing to keep careful track of their food intake and to do high levels of physical activity. Some people who have reached a healthy weight may find it hard to keep the weight off.
