I find that for me scrupulous adherence works better than anything else. I think it all depends on goals, lifestyles, priorities, physiological flexibility (some of us just aren't too flexible physiologically when it comes to carbs). I don't like the word "cheat" but self-honesty is important. Is what you are doing letting you achieve your goals? If not change it and recognize the difference between reasonable flexibility in your eating choices and giving yourself excuses.
