If you are overweight or have obesity, losing weight can improve your health. It might also help you prevent weight-related diseases, such as heart disease, diabetes, arthritis and some cancers. A healthy diet is an important part of a weight-loss program. It:
May include fruits, vegetables, whole grains, and fat-free or low-fat milk and milk products
May include lean meats, poultry, fish, beans, eggs and nuts
Goes easy on saturated fats, trans fat, cholesterol, salt (sodium), and added sugars
The key to losing weight is to burn more calories than you eat and drink. A diet can help you to do this through portion control. There are many different types of diets. Some, like the Mediterranean diet, describe a traditional way of eating from a specific region. Others, like the DASH eating plan or a diet to lower cholesterol, were designed for people who have certain health problems. But they may also help you to lose weight. There are also fad or crash diets that severely restrict calories or the types of food you are allowed to eat. They may sound promising, but they rarely lead to permanent weight loss. They also may not provide all of the nutrients your body needs.
In addition to a diet, adding exercise into your daily life can help you to lose weight.
