I started out zero added sugar and was attempting to stay thyroid-friendly as I have problems with my thyroid but that proved far too difficult. As I restricted sugar more and more I found I was better off low carbs. I've also got rid of the polyunsaturated fats in favour of healthy full saturates like butter and coconut oil. I've remained strict as far as added sugar is concerned but have allowed fruit back now my addiction to sugar is gone. What works for you?
