I don't know what you mean by the ribs "sticking out", but most web sites say if you can see the last 3 ribs on a greyhound, the dog is at a healthy weight. I also know that my 6 year old 75 pound male greyhound eats about as much as a hundred pound dog should eat (at least according to the guidelines on the bag of food), in order to maintain his weight. I give him a good quality higher protein dog food, again at the recommendation of greyhound web sites. He is not that active: gets two 20 minute walks and a brief run daily. A greyhound that is actively racing can double his daily caloric needs. So when I send him to the boarding kennel when I go on vacation, I increase his daily food allottment by 25-50%, because if I don't, his weight will drop, even though they say he eats all his food. Hope this has been helpful.
