I agree that the best thing about the Insulin Resistance diet (especially in the longer term) is that you don't have to feel deprived, as long as you approach it sensibly.

There is a section on "splurging" which helps you to realize you can incorporate the occasional treat, look forward to the indulgence and really savor it. It won't ruin your efforts or make you feel you've "blown it". The only danger is that some people will take it as a license to overindulge.
