They divided into three groups. The first group is consume half grapefruit every time before meal, the second group is drink a glass of grapefruit juice every time before meal, and last group is not consume grapefruit at all.

As long as 12 weeks, all the participants don’t show significant changes in their diet and exercise. After 12 weeks, result show that the first and the second group have derivation of weight each for 1.8 kg and 1.6 kg, also they show derivation on insulin level. While the third group show that they loss their weight less than 0.5 kg and the insulin level show there’s no significant changes. Researches guess, that insulin is the one who play important role in weight loss.
