I too just started the 17day diet today.  I want to loose 50lbs by July.  Today was really a good day.  Hardly any cravens.  I think it's due to drinking the green tea.  My problem is night timeeating.  I decided to save my yogurt smoothie for my last snack.  I'm going to see how this works for me. I plan to exercise about 5 times a week for at least 45mns to an hour.  I will keep all of you inform as to how I am progressing after my 5th day.  I'm going to weight myself in 5 days.  Good Luck to everyone that's on this diet!
