What you are talking about Risha is CAD or CALP and there are some rules. That I couldn't handle.

Like: you can have a cup of coffee but it must be drunken within 15 minutes - no artificial sweetners or diet sodas unless during your reward meal - no snacking just 3 meals and the other two are low carb - eat your reward meal within 1 hour

CAD is almost anything in the reward meal and CALP should start with a salad and be equal parts of protien/carbs/fat

Anyone can correct me if i'm wrong here.
