Before I run out and buy a dozen grapefruit, I'd like to know more about this ..

.. And, much to our surprise, without really altering their diet, they lost 3½ pounds or a pound a week without really doing anything else ..

What does "really" really mean?? If the participants self-reported their diet, or filled out a questionnaire, this whole study becomes iffy due to the well-known tendency for people to under-report their food intake. It would've been more accurate for the researchers to assign a standardized, non-low-calorie diet for all to follow and track their progress over the 12 weeks.

All this study suggests is that grapefruit seems to contain a substance which may improve insulin sensitivity which is worthy of further research.

I think that this report ties in nicely with the news that the Florida citrus growers' sales are sluggish...
Just my opinion, but what do you think?
