Why are some people who are diagnosed with diabetes mellitus not compliant with their dietary regimen?

If only I knew...: Compliance with physician advice (dietary or otherwise) is very individual. Some patients lack confidence in the advice they are given, some choose to eat what tastes good and makes them happy, some lack self-control, some are sabotaged by other friends/family who set them up to fail. The only difference between my health today & my health in 7 days are the choices i make every day this week.
