Hello lybrate-user! having only juices will not help you to loose weight you need to take proper diet and exercise which will help you loose weight and have a healthy body. To overcome obesity avoid fatty and fried foods and excess sugars in the form of cold drinks and preserved juices. Include protein rich foods which include pulses, milk and milk products, eggs and chicken, should have fibre rich foods which help you to pass smooth bowels. Have lots of vegetables and fruits. Include 5 almonds or 5 pieces of walnuts once a day daily in your diet. Do exercise for atleast 30 to 40 minutes. Thank you.
