A lot of advice nowadays is to give the cat more exercise by, for example, actively searching for his food (food enrichment). This can be done, for example, by using unique balls in which chunks fit. It is also possible to hide small bits of food in different places. These kinds of hiding places can be made by yourself (e.g., by using toilet rolls that can be taped together between the heaters), but there are also specialized wooden puzzles available for this purpose.
