For this to be successful for anyone, it is necessary to adjust your diet within your individual tastes in accordance with the recommendations from your program. Basically, protein and vegetables are the mainstays of your daily intake with some other things added as you go along. If you mean picky like only eating fast food and junk food then you are going to have problems. My friends sister had GBP (paying cash) and lost a grand total of 12 pounds in a year because the only things she "liked" were chocolate milk. macaroni and cheese and cashews. It is important to be open to change your diet unless you want to stay at a dangerously unhealthy weight.
