it requires a strong self discipline and courage my friend..yes, fruit diet is one option but you have to take carbs also since you need energy for your exercise routine..just control your eating habits..you can still eat cake and chocolates once a week. Let's say a bite and a small slice..green apple really helps and banana..every morning before u eat anything have a glass of warm water and a drop of lemon juice on it..its a good detox..

hope u you will find this tips helpful

and last thing dont check your weight everyday you can doit once in 2 weeks or once a week

goodluck!
