According to a BBC report, Scientists at Newcastle University said alginate, a compound found in common seaweed (kelp), can stop the body from absorbing fat.
Research findings showed that a 400% increase in a type of alginate reduced fat absorption by 75%.
Alginate works because it reduces fat breakdown by a digestive enzyme, pancreatic lipase.
If you block the action of the enzyme you lower the amounts of fat being absorbed by the body.
The scientists say the next step is to carry out large clinical trials to find out how effective alginates are when they are eaten as part of a normal diet.
While acknowledging that alginate from kelp could fight obesity, dieticians point out the best way to reduce fat ingestion is to not eat it in the first place.
