From Real Age:
In a study, obese people who ate half a fresh grapefruit before meals showed improvements in two important measures related to the syndrome — weight, and insulin response.
Not only did the grapefruit eaters shed pounds, but
their insulin resistance improved, too.
Word of caution: Grapefruit increases the effect of some medications, so be sure to check with your doc
tor or consult drug interaction sites online.
