Fish-rich diet helps to reduce weight: Study
London, July 07: And if you thought that eating fish could only increase your brains, think again, a study of African tribes suggests that the one with a fish-based diet had lower levels of a hormone which influences appetite. It suggests that people eating a fish-rich diet may find it easier to control their appetite also the needle of the weighing machine.

Mayo Clinic researchers looked at the levels of the hormone leptin in men and women. Leptin is produced by fat cells, and its role, in people with normal weight, is to tell people when they have had enough food. They do this by producing the feeling of "satiety", or fullness.
The researchers found that, on average, the fish-eating men had lower leptin levels than women. And those on non-fish diet had a lower average reading than women. The researchers said that the readings for women were particularly significant, as normally, women have higher leptin levels than men - which was not the case when women from the fish-eating tribe were compared with vegetarians.

However, the findings do not prove that reducing leptin levels can improve cardiovascular health. Professor Virend Somers, from the Mayo Clinic, said, "We speculate that fish diet may change the relationship between leptin and body fat and somehow make the body more sensitive to the leptin message. However, this study only describes an association."
"We don't know if the findings will apply to a semi-overweight, urban-dwelling, North American population," he added.
