Diet capsules that swell in stomach could help weight loss
Plenity contains hydrogel made from cellulose, which is found in fruit and vegetables
Gel capsules that part-fill the stomach before a meal may help people lose weight and keep it off, the European Congress on Obesity was told on Sunday.
The hydrogel capsule first made news in 2010, when it was called Attiva. Now, as Plenity, it has been trialled on more than 400 people. It worked on only 59% of people, but in those, it doubled their chances of losing 5%-10% of their bodyweight.
