Grapefruits are low in kilojoules and high in enzymes that burn fat. Here’s how drinking grapefruit juice can benefit weight loss and boost your metabolism.
When obese adults who were dieting ate half a grapefruit or drank half a cup of grapefruit juice or half a cup of water 20 minutes before each of their three daily meals, they all experienced significant drops in weight, BMI and waist circumference, losing an average of 7kg over the course of 12 weeks, a study at Vanderbilt University in the US found. The juice drinkers also reported less hunger compared with the water sippers. And – important for your heart – both grapefruit groups (juice and whole fruit) experienced a significant jump in good HDL cholesterol.
