If anyone were so inclined, it would probably be quite possible to find a diet on the market today that included every food source known to man, in specific portions to be eaten at specific times of the day or night.
There are diets that forbid certain foods and demand that you eat at least five portions of certain other foods. There are diets that will cause you to lose all of that unwanted poundage – in one month or your money back.
If this sounds a little exaggerated, take a look on the Internet. Make it a long look – it will take you days at least. Now pick one that appeals to you and try it for the suggested length of time. No cheating. No substitutes. Eat and drink only what is prescribed, as much or as little as prescribed. Having fun yet?
The fact is that anybody can come up with a “sure-fire” weight loss program, and a great many have done so. These diets are often based on a theory that has not been proven by any sort of scientific research.
It is also a fact that “natural” food supplements are unregulated and can make claims about healthful or healing qualities without regard to proven results or lack thereof.
There are diets whose results are “proven” by data that is completely fabricated by those who are trying to make some money by convincing the uninformed or gullible public to buy a “quick fix”.
There are too many examples to count, but as a general rule these short-cut diets are potential hazards to your health, your wallet and your peace of mind.
Take as just one example the marvelous “Mayo Clinic Diet”. There is no such thing, according to personnel at the Mayo Clinic. Various pretenders to scientific knowledge have used its name, but the Clinic itself has never promoted or endorsed any of the “Mayo Clinic” diets.
Another well-known example is the Vitamin C craze initiated by Linus Pauling, a Nobel laureate. His claim about the efficacy of Vitamin C in the cure of not only the common cold but also cancer was simply never substantiated.
For much of the general public, if something can be made to look and sound like an authentic scientific presentation, it becomes a “fact”. In far too many cases, the “facts” are drawn from unconfirmed and unrelated sources – but they sure sound good. It is only human nature to look for the quicker, easier way.
No matter how long and hard you search, if you are honest with yourself a few ‘hard facts’ will emerge. If you consume more calories than your body uses, they will be stored – as extra weight.
If you use more calories than you ingest in the food you eat, you’ll lose weight, whether it’s stored in fat or in muscle tissue or bone. The ‘secret’ is not a secret; it’s been known for thousands of years. Exercise and moderation will win over any quick fix, and that’s good for a lifetime.
Almost by definition, a ‘fad’ diet is one whose popularity is based more on publicity than on confirmed results. The frequent claims of proponents who are quoted making such statements as, “I lost thirty pounds in three weeks!” can and often do lead to dangerous misconceptions. 
The best selling book according to the New York Times, is a book called The Sonoma Diet. The Writer is a Dr Connie Gutterson who came up with the idea of the Sonoma Diet program. The Sonoma Diets is written about foods from the Mediterranean, with them coming from California, Sonoma and The European Mediterranean. Comprising diets from Asian, Mediterranean and Latin America cultures.
