People of Chennai, do you think ghee is unhealthier than oil

As part of eating Chennai food like idli I prefer to add ghee instead of oil. But i rarely do it, because "ghee will make you gain weight". Similarly in Chennai, I like to eat ghee roast instead of normal Dosa with oil. Im not fat but i have a gut i want to reduce. Fellow Chennaiites, do you add ghee instead of oil. Is nei/ghee worse than oil or no difference? Ps, adding lot of "chennai" keywords or else mods like to remove your post. :1984:
