Its thought that there is a magical ingredient - an enzyme - in grapefruit, that when eaten with protein, triggers fat burning and weight loss. So the whole diet is low carb and high protein, not a million miles away from the Atkins diet. No scientific studies back up this power to burn fat. There was one study that found that it worked - and that was funded by the Florida Dept of Citrus. Its a low calorie, low insulin fruit. So it may help you feel full so you dont eat as much after. But I dont think theres any magic in it. You need to eat a wide variety of healthy food and exercise plenty. But you already knew that! Go for grapefruit - they taste great!    WhittleAway 02-08-2010 @ 2:15 PM                           reply Member Joined: Jan 2010 I tried that diet 20 years ago! I guess like with all things, it comes round again. It didnt work for me - hence why I came here looking for slimming pills - I just ate the same as I did before with a grapefruit on top! I'm sure if you can stop after the grapefruit, you'd look fabulous! cindy74 02-11-2010 @ 3:24 PM                           reply Member Joined: Jan 2010 hey there Im with you whittle - that grapefruit diet has been around for years and years! not sure its effective though! I dont really like the taste of it either, too bitter for me! I reckon if you eat a big breakfast and then a good lunch, a small dinner and a few snakcs, that shoud be good right? and yes, exercise is always the one thing we all need to do more of!! but sometimes its easier said than done right!!
