I put on in the first week but I have a feeling a lot of that was to do with the fac.t I tried EE and it wasnt explained to me at all about he 1/3 rule. I dont eat meat and I was starving all the time until I switched to Green days.
You have to remember that scales dont weigh you week to week as your weight doesnt follow a week to week pattern it could be it takes two weeks or more for your body to catch up with the changes
Also if you dont have a lot to lose then yes it could be a lot harder
But dont give up and I am sure you will be pleasantly surprised
