The outcomes of the study were published Wednesday through the journal PLOS ONE.

The findings come with several caveats. For starters, the research was paid for by the California Grapefruit Growers Cooperative. But the Berkeley
researchers, in the university's paiyouji plus Department of Nutritional Sciences and Toxicology, insisted that they entered the research with lots of skepticism
concerning the dietary power of grapefruits.

"I was surprised at the findings," Andreas Stahl, the study's senior author, said inside a statement in the university. "We even re-checked the calibration
of our glucose sensors, and that we got exactly the same results over and over again."

Also, the research was small, with every mixture of diet, liquid along with other nutrients tested in categories of just six mice.

Not to mention, what goes on in mice won't necessarily happen in people.

Still, the outcomes may help explain why grapefruits are often featured in fad diets.

Mice don't care for the bitter taste of grapefruit juice, which comes from the flavonoid called naringin. In previous studies of mice that slimmed down when
given grapefruit juice rather than water, their weight loss could have been due to the fact the bitterness caused these to lose their appetites.

The Berkeley researchers hoped to solve this problem by doing two things. First, they sweetend the pulp-free grapefruit juice (produced from California Ruby
Red grapefruits) with 7 days herbal slim saccharin. Second, they gave mice in the control group sugar water created using glucose and saccharin that had the same amount of
calories as the sweetened juice.

In the experiments, mice offered grapefruit juice and water drank similar amounts. (They also ate similar amounts of food.)
