Weight loss is a really personal thing. My diabetic husband was overweight for years. It took me almost 5 years to get him to switch to my LC diet. The way I did it was to stop buying any carby food anymore. So I cleared out the pantry of dry cereals, rice, pasta, crackers, etc. I assume she does the cooking. Since I do the cooking it is easier for me to make low carb meals. If I were you I would sit down and plan your meals and shopping together. I know you exercise a lot. Maybe you could find an exercise that includes her. I know when you start to exercise you do feel so much better about yourself and will want to find a diet that gives you more energy. I know for me the hardest part of going LC was giving up all those whole grains, and they were my problem. I assumed they were healthy so I overate them. Get the book WHEAT BELLY, by Dr William Davis for her to read.
