To successfully lose weight, you must carry out a plan that
balances the calories you eat every day with your activity and
exercise. Ideally, dieting should be done by eating a
nutritionally balanced, low-calorie diet and increasing physical
activity. Although there are many programs advertised to help
you lose weight, the only proven long-term and safe method is to
burn more calories than you consume. This is achieved either by
reducing the caloric intake (eat less food or healthier food) or
by increasing the energy expenditure (exercise more). Often,
behavior modification techniques like eating smaller portions
are used to help control eating habits. Once the weight is lost,
these habits can be modified slightly for weight maintenance. If
you have unintentional weight loss , it can be a symptom of
various medical or psychiatric disorders, or it can be due to
increasing your exercise or decreasing your food intake. HEALTHY
