When the vet said my cat Bobby needed to lose weight, he recommended a special bowl. It had different compartments, so Bobby had to work harder for his food, but it was expensive. So I made my own. I cut the bottoms off some empty washing-liquid bottles and stuck them together with double-sided tape. Then I stuck these to an old mouse mat to give it some grip. It has stopped Bobby gulping food and will hopefully help him shift the weight.
