Hi George

a 900 calorie intake daily is under the recommended dose. However, everyone is different. If you feel healthy and this amount has been working for you than that should be fine. However, we always recommend consulting a doctor to make sure you are receiving the correct nutrients and energy that your body needs. OneHOWTO
