My girl friend is 23 her weight is 54 kg now she wants to be more slimmer and her tummy is out too. kindly tell me some natural tips.....

See Dr., and then...: Helpful weight loss diets have natural foods that take time to chew but contain few calories. Examples include carrots, celery, and iceberg lettuce (little/no salad dressing). When shopping for fruits, buy small ones no bigger than a tennis ball, because fruits have sugar. Drinks without calories include water and green tea. A calorie is a calorie, but surely avoid sugar & simple starch calories.
