Today the worldwide prevalence of obesity is increasing, both in rich and poor countries. This global epidemic is reaching pandemic proportions, and can be attributed to a number of factors. Contributing to the problem are insatiable cravings for sweets, hormone imbalances and related endocrine disorders, and easy access to inexpensive junk food that poses a long-term risk to health.

As a result, there is huge demand for products that would combat obesity - and an ever increasing supply. Many people claim they have discovered a miraculous weight loss cure, or fat burning liquid or other substance that can make one slim with no effort. As a consequence, separating legitimate claims and scientific novelties from scam and pseudoscience that can only make you poorer, not slimmer, is more and more difficult.

One of criteria for discerning between scam and reality can be experimental evidence. If people indeed are burning their fat due to some weight loss cure, even more so if the loss is permanent and certified by doctors - it is definitely more credible than one that only portrays fake images of 'before' and 'after' poorly edited in a graphic program.

The Science behind any particular scheme or weight loss cure may be considered as one of the criteria's. An project can score higher in one's private credibility ranking if its able to describe how and why it can attain the claimed results, for example, it allows you to reset your hypothalamus or get a new taste for healthy foods.
