It is not good to be so obsessed with one’s weight. Minor weight fluctuations occur daily due to loss of fluid and diet. It is important to eat a balanced diet and include variety of foods from different food groups. Fruits and vegetables can give enough sugar, vitamins and minerals but are a poor source of proteins. She should eat a balanced diet with cereal and grains, fruits, vegetables, milk, small amount of fat and meat (if she is a non-vegetarian). Eating in moderation but balanced will help you in long term. It is not essential to include all the three proteins, carbohydrates and fats in the same proportion in all the five meals. She can have meals at a gap of 3 hours. An inclusion of all should be ensured in her breakfast and lunch whereas the mid-meal snacks and dinner may be just proteins or carbohydrates. Make sure she does not use any saturated fats like ghee, butter and cheese for the preparation of meals. Eat small meals slowly. Go for a brisk walk for half an hour everyday. Being active will only make her feel energetic the whole day. She should drink at least 10 glasses of pure water everyday and should treat herself to her favourite foods only once in fifteen days. If this behaviour persists, she should consult a psychiatrist.
