Grapefruit is one of the healthiest citrus fruits.
Besides being a good source of vitamins and minerals, it is known for its ability to aid weight loss and reduce insulin resistance.
For example, in a study in 91 people, those who ate half a fresh grapefruit before meals lost 2.9 pounds (1.3 kg) more weight than those who didn’t ( 1).
In the same study, the grapefruit group had a significant reduction in insulin levels and reduced insulin resistance (1 ).
Also, eating grapefruit has been shown to reduce cholesterol levels and help prevent kidney stones
