New help with post-op diet

My wife finally saw a doctor--after 10 years--and she is addressing all of her medical problems.  She found out that she has high blood pressure, is borderline diabetic, and has high cholesterol and triglycerides.  As a result, she is totally compliant following a new diet.  She is weighing and measuring her food at all meals and snacks.  I'm proud of her and I'm inspired to be compliant also.  Not having junk in the house will be good for both of us.
