After using this i can only say that to maintain a normal BMI or normal weight is eat hard and work hard. This app and these diet plans are only for the people who are having a normal schedule in day to day life but not for the busy scheduled people. Unless or until you are very much confident in following these diet plans, i personally don't recommend this to take. That's my personal opinion. There is no other option called Refund. So think before buying the plans. Thank you.
