Query: Hey, has anyone out there checked their cholesterol lately?

In January of '99 I had a complete blood work up. My total cholesterol was 230. Three weeks ago I began the Atkins diet. I loved it. Any why not? I got to eat cheese and meat ad nauseum (and I was frequently nauseated). Last week I had anothrt blood work-up: My cholesterol had skyrockerted nearly 50 points to 279! Now, as a rational human being I realize that only three weeks of the Atkins diet could not have been responsible for that huge jump in total cholesterol...but it sure as hell didn't help. Watch yourselves out there, folks. And have your cholesterol checked!
