Well handled! I probably wouldn't have had as much self control. Next time they throw that "the way you're eating is going to kill you" line, ask them to show you the study that shows how many people have been shown (conclusively) to have died as a direct result of eating low carb. They'll probably quote all the studies regarding high fat at which point you can also point out that in those studies about high fat, the subjects were also eating high amounts of carbs, so it doesn't apply to your situation. I often wonder how many dieticians keep up with the cutting edge of nutrition once they are done with school. From what I'm hearing, it's not many.
