There seem to be many people that claim grapefruit, in one form or another, helps dieters with weight loss.
Is there any good academically-rigorous evidence to support any of these claims?
Some of the claims:
People who ate half of a grapefruit before each meal (without making any other dietary changes) shed an average of three and a half pounds over 12 weeks, found a study from the Nutrition and Metabolic Research Center at Scripps Clinic in La Jolla, California."
The fruit's compounds aid in fat burning and stabilizing blood-sugar and insulin levels,' says Christine Gerbstadt, MD, author of Doctor's Detox Diet.
Further evidence of notability is the 'Grapefruit Diet', which Wikipedia describes as a fad diet.
