Yes, when I lost all my excess weight and needed to stop losing and maintain, I kept my carbs very low but increased protein and fats. It was quite hard at first to get the right balance - I had to use my bathroom scales alongside my blood glucose meter and go back to basics with my food diary. It is a fine balance, but once I found the right balance it was fine. I have now maintained for 4 years. I did it mainly from eggs, cheese, butter, mayo and a glass of wine each evening. I have always eaten plenty of protein as I am a great believer in it, especially as we age, so have never restricted it and eat a lot more than the normal RDA so increasing my portions of meat and fish was not really an option.
