People gain weight when the number of calories they eat is more than the number of calories their bodies use. Overweight people have an increased risk of high blood pressure, heart disease, and other illnesses. Your doctor can help you set rational goals based on a proper weight for your height, build and age. Usually, doctors will recommend that their overweight patients combine a reduction of the caloric content of the diet, with an increase in physical activity. Other methods of losing weight include use of drugs and supplements that decrease appetite, block fat absorption, or reduce stomach volume. Surgery is another method. Weight-loss programs should encourage healthy behaviors that help you lose weight and that you can stick with in your every day activity. It is very desirable for you to gather as much information as you can before deciding to join a particular program. You may start to benefit from regular physical activity. Even modest amounts of physical action can improve your health. Start with small, specific goals such as walking 10 minutes a day, 3 days a week. When you eat out and are on the go it’s important to make smart food choices and watch portion sizes. When you prepare food at home read the nutrition label on foods. Look for foods low in saturated fats and trans fats. Choose and prepare foods and beverages with little added sugars (caloric sweeteners). Variety in the diet helps you get all the vitamins and other nutrients you need. Look for a weight loss program that gives you some control, rather than imposing one rigid system, one that offers a variety of different eating plans, so you can choose the one that's best for you. Prescription diet pills may help some people. If you use them, follow the doctor's directions carefully. Other method of weight reduction technique is the use of diet patches.
