In an age of marketing gimmicks and quick fix solutions, the fad diet is the King of the dieting world. The grapefruit diet, the cabbage diet, even the Atkins diet are to be blunt a waste of your time. Anything that is short term and unsustainable, in other words, anything that doesn't instill new and long lasting habits in your food intake , is in my opinion both a fad and counterproductive to your long-term success. If you can't incorporate and apply what you do (in this case your diet) into the real world around you, then surely it is of no use at all.
Fad diets, as well as almost always being unhealthy and nutritionally inadequate, and unsustainable eating plans always fail, and invariably send their users back to a more negative stage than when they started!
The take home message here is to be patient, take your time, and work on creating positive habits for the future not just for one fleeting moment.
