Can grapefruit alter your metabolism?
Asked by anonymous on Jan 12, 2009 in Weight Loss


Grapefruit could affect nutrient metabolism.  In a 12-week pilot study, scientists at the Scripps Clinic monitored weight and insulin levels on 100 obese people.  Before each meal three times a day, some of the participants ate ½ grapefruit or drank grapefruit juice while others did not. The grapefruit-consumers lost about 3.5 lbs while the non-eaters lost only ½ lb.  Chemicals in grapefruit might reduce levels of insulin, a hormone that helps with the regulation of fat metabolism. A smaller post-meal insulin spike could help the body to process energy more efficiently, which could lead to less fat storage.  More research is needed to confirm the hypothesis, but meanwhile, there is no harm in eating grapefruit.
