British scientists claim to have engineered a new food that can make you feel twice as full. It is a certain mixture of olive oil, water and a stabiliser already used in the baking industry.
The new food can keep people feeling fuller for 12 hours after eating.
But this potential weapon against obesity could take ten years to hit the supermarket shelves, said researchers with the Institute of Food Research, Norwich.
Dr Martin Wickham from IFR said: 'This is the first time that we have seen such a dramatic effect from a model meal.
'This formulation could be used as an ingredient in new foods to make them more filling, which in turn could help reduce overconsumption of calories.'
The mixture has been developed by Dr Wickham and Richard Faulks at the Institute of Food Research and its effects tested by scientists at Nottingham University.
They used an extra-fast type of MRI scanning to show the effects in the stomach.
The three-year project has found that emulsions of olive oil and water - the same principle as a salad dressing - can be altered to affect how they react in the acid environment of the stomach.
Scientists made two types of emulsion stabilised with different compounds commonly used in the food industry.
One used a kind of polysorbate surfactant called Tween 60, which is widely used in cakes and pastries, and the other used a polysorbate surfactant called Span 80.
