An anti-hunger additive, the latest version of methyl cellulose, is now being included in yoghurts and smoothies to assist people in losing weight.
The ingredient known as SATISFIT-LTG, is being developed as a slimming aid as it enables a feeling of fullness and satiety after eating.
Dr Carsten Huettermann, from Dow Wollf Cellulosics in Bomlitz, Germany, said, "This ingredient would make people feel full after eating smaller amounts of food. With that sense of fullness and hunger-satisfaction, they would not crave more food.
This ingredient also reduced the calorie intake of volunteers by 13 per cent.
