Being a ‘newbie’ is not a time dependent phase. It’s an attitude. The longer you eat lo/no carb, become more efficiently fat adapted, experience both foreseen and unforeseen benefits, the less you think you’ve given up something. Instead, you realize you have gained something far better. As your appreciation grows that you gained something valuable, the feeling you gave up something weakens. Finally, you realize you are where you want to be, want to remain and see no point leaving. Ever. At that point, you are no longer a ‘newbie’. Doesn’t matter whether it took you 6 months, 12 months or 5 years to get there.
After your newbie attitude changes, so-called cheat days are no longer an issue. You don’t want to eat that stuff any more so you don’t. Family gatherings and social events are no longer an issue. You politely decline to eat stuff you don’t want to eat any more. You find a way because you are NOT making a sacrifice. You ARE instead celebrating good health and nutrition - and enjoying the benefits of it.
