Want to shed flab? Well, you can now gorge on a special chocolate to lose weight, provided you don't mind its green tinge.

Sounds strange, but scientists have produced a new kind of chocolate, called Lola, which contains chemicals that trick one's brain into believing that one is not hungry and stops one from over -eating, the 'Daily Mail' reported.

However, the scientists from Spanish manufacturer Cocoa Bio claim that though the chocolate tastes just like regular bars, they have a slight green tinge because of the unusual extra ingredients.

"People should eat one or two chocolates around one hour before a meal. They'll feel pleasantly full and less like eating to excess. The chocolate has an intense flavour and extremely high antioxidant properties," lead scientist Armando Yanez, was quoted as saying.

He said the green tinge is because the chocolate contains the dietary supplement spirulina, a microscopic algae with a high level of nutrients such as vitamin A and B12, which also have weight loss benefits.

The scientists also claim that amino acids in the recipe stimulate the production of a hormone in the brain which suppresses the appetite.

The chocolates, priced about 5 pounds for a box of five will initially be sold only in Spain, but may come to Britain if there is enough interest.

It is not the first time that the potential health benefits from regularly eating chocolate, especially dark chocolate, have been identified.
