The most important point that you made was having lost the taste for the 'damaging' foods - it is so difficult to
impress upon the newly diagnosed (I know you are not a newby) that they will not miss their favourite foods within
a matter of days and that their taste buds will adjust with no poblem.
Please get your wife on board. Eating is what we do three times a day and eating together is one of the joys of life. Not so much fun though if you are always eating differently. It will be easier to maintain your progress if your wife shares the way of eating and probably healthier for her.
