An increasing number of people both in developed and developing countries combat obesity nowadays. It is becoming more and more of a pandemic, and has a variety of causes. Those can range from unstoppable love for sweets through hormonal imbalances and other medical related problems to wide availability of cheap, unhealthy and fattening foods.

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.

Experimental evidence can help to discern between scam and reality, as a weight loss cure resulting in permanent weight losses certified by doctors can definitely be quite credible. On the contrary, if an advertisement only portrays fake images of 'before' and 'after' poorly edited in a graphic program - the scheme behind it is probably a fake.

Another criterion may be the science behind any particular scheme or weight loss cure. A project that can describe in detail how and why it attains the claimed effects - for example allows you to reset your hypothalamus or get a new taste for healthy foods should immediately score higher in your private credibility ranking.
