I'm trying to loose weight. I'm exercisng and basicaly just trying to eat sensibly. Can going on a grapefruit for breakfast diet help me loose weight? Can i mix it half grapefruitand half orange. Will grapefruit Juice also work?
The Grapefruit Diet had it's day...sometimes called the Steak and Grapefruit Diet.
The "theory" was that since citric acid was an integral part of the Krebs Cycle, that extra citric acid would disrupts it prevent the use of some carbohydrates.
Nice theory that never worked in the real world.
BUT, if all you have is a grapefruit instead of a meal, THEN you will lose weight because you are restricting your calories...and that is the only way that ANY diet is successful.
