Satiating refers to satisfying hunger, but if you want to describe something that isn't as fulfilling, you could use antonyms like unsatisfying, unfulfilling, or uninspiring. These words indicate that something doesn't provide the same level of satisfaction as a more satiating option. For example, a bland salad may be unsatisfying compared to a juicy cheeseburger. Similarly, a simple bowl of oatmeal may be unfulfilling compared to a savory breakfast sandwich. By using antonyms for "more satiating," you can convey that something is lacking in terms of filling up or satisfying your appetite.
