Deposition of fat in abdominal area is a kind of central obesity. There are many causes of central obesity such as increased food consumption without increasing physical activity, high junk food, Cushing’s syndrome, and hypothyroidism. There are many more uncommon causes. There is very little research on fish oil in obesity. It is better to do lose weight in a natural ways rather than taking fish oil. I do not recommend to you to take fish oil. It has no role.
